The option framework documentation was speaking about a 'print -raw'
option, but this option does not exist.
This patch implements -raw-values option that tells to ignore the
active pretty printers when printing a value.
As we already have -raw-frame-arguments, I thought -raw-values
was more clear, in particular to differentiate
set print raw-values and set print raw-frame-arguments.

2019-12-11 Philippe Waroquiers <philippe.waroquiers@skynet.be>
* gdb.texinfo (Command Options): Use -p and -pretty in the example,
as -r is ambiguous. Update the print - TAB TAB completion result.
(Data): Document new option -raw-values. Use -p and -pretty in the
example, as -r is ambiguous.
(Print Settings): Document set print raw values.
(Pretty-Printer Commands): Document interaction between enabled
pretty printers and -raw-values/-raw-frame-arguments.

I happened to find a few more spots that should use metadata style,
but do not. I missed these in my earlier search somehow. This patch
also adds gettext markup in a couple of spots where it was missing.

- Rationale:
It is possible for compilers to indicate the desired byte order
interpretation of scalar variables using the DWARF attribute:
DW_AT_endianity
A type flagged with this variable would typically use one of:
DW_END_big
DW_END_little
which instructs the debugger what the desired byte order interpretation
of the variable should be.
The GCC compiler (as of V6) has a mechanism for setting the desired byte
ordering of the fields within a structure or union. For, example, on a
little endian target, a structure declared as:
struct big {
int v;
short a[4];
} __attribute__( ( scalar_storage_order( "big-endian" ) ) );
could be used to ensure all the structure members have a big-endian
interpretation (the compiler would automatically insert byte swap
instructions before and after respective store and load instructions).
- To reproduce
GCC V8 is required to correctly emit DW_AT_endianity DWARF attributes
in all situations when the scalar_storage_order attribute is used.
A fix for (dwarf endianity instrumentation) for GCC V6-V7 can be found
in the URL field of the following PR:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82509
- Test-case:
A new test case (testsuite/gdb.base/endianity.*) is included with this
patch.
Manual testing for mixed endianity code has also been done with GCC V8.
See:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82509#c4
- Observed vs. expected:
Without this change, using scalar_storage_order that doesn't match the
target, such as
struct otherendian
{
int v;
} __attribute__( ( scalar_storage_order( "big-endian" ) ) );
would behave like the following on a little endian target:
Breakpoint 1 at 0x401135: file endianity.c, line 41.
(gdb) run
Starting program: /home/pjoot/freeware/t/a.out
Missing separate debuginfos, use: debuginfo-install glibc-2.17-292.el7.x86_64
Breakpoint 1, main () at endianity.c:41
41 struct otherendian o = {3};
(gdb) n
43 do_nothing (&o); /* START */
(gdb) p o
$1 = {v = 50331648}
(gdb) p /x
$2 = {v = 0x3000000}
whereas with this gdb enhancement we can access the variable with the user
specified endianity:
Breakpoint 1, main () at endianity.c:41
41 struct otherendian o = {3};
(gdb) p o
$1 = {v = 0}
(gdb) n
43 do_nothing (&o); /* START */
(gdb) p o
$2 = {v = 3}
(gdb) p o.v = 4
$3 = 4
(gdb) p o.v
$4 = 4
(gdb) x/4xb &o.v
0x7fffffffd90c: 0x00 0x00 0x00 0x04
(observe that the 4 byte int variable has a big endian representation in the
hex dump.)

This introduces a new "metadata" style and changes many places in gdb
to use it. The idea here is to let the user distinguish gdb output
from output that (conceptually at least) comes directly from the
inferior. The newly-styled category includes text that gdb
traditionally surrounds in "<...>", like "<unavailable>".
I only added a single test for this. In many cases this output is
difficult to test. Also, while developing this errors in the
implementation of the new printf formats showed up as regressions.

With this patch, the help docs now respect 2 invariants:
* The first line of a command help is terminated by a '.' character.
* The last character of a command help is not a newline character.
Note that the changes for the last invariant were done by Tom, as part of :
[PATCH] Remove trailing newlines from help text
https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html
but some occurrences have been re-introduced since then.
Some help docs had to be rephrased/restructured to respect the above
invariants.
Before this patch, print_doc_line was printing the first line
of a command help documentation, but stopping at the first '.'
or ',' character.
This was giving inconsistent results :
* The first line of command helps was sometimes '.' terminated,
sometimes not.
* The first line of command helps was not always designed to be
readable/understandable/unambiguous when stopping at the first
'.' or ',' character.
This e.g. created the following inconsistencies/problems:
< catch exception -- Catch Ada exceptions
< catch handlers -- Catch Ada exceptions
< catch syscall -- Catch system calls by their names
< down-silently -- Same as the `down' command
while the new help is:
> catch exception -- Catch Ada exceptions, when raised.
> catch handlers -- Catch Ada exceptions, when handled.
> catch syscall -- Catch system calls by their names, groups and/or numbers.
> down-silently -- Same as the `down' command, but does not print anything.
Also, the command help doc should not be terminated by a newline
character, but this was not respected by all commands.
The cli-option -OPT framework re-introduced some occurences.
So, the -OPT build help framework was changed to not output newlines at the
end of %OPTIONS% replacement.
This patch changes the help documentations to ensure the 2 invariants
given above.
It implied to slightly rephrase or restructure some help docs.
Based on the above invariants, print_doc_line (called by
'apropos' and 'help' commands to print the first line of a command
help) now outputs the full first line of a command help.
This all results in a lot of small changes in the produced help docs.
There are less code changes than changes in the help docs, as a lot
of docs are produced by some code (e.g. the remote packet usage settings).

I touched symtab.h and was surprised to see how many files were
rebuilt. I looked into it a bit, and found that defs.h includes
gdbarch.h, which in turn includes many things.
gdbarch.h is only needed by a minority ofthe files in gdb, so this
patch removes the include from defs.h and updates the fallout.
I did "wc -l" on the files in build/gdb/.deps; this patch reduces the
line count from 139935 to 137030; so there are definitely future
build-time savings here.
Note that while I configured with --enable-targets=all, it's possible
that some *-nat.c file needs an update. I could not test all of
these. The buildbot caught a few problems along these lines.

This is the next patch in the ongoing series to move gdbsever to the
top level.
This patch just renames the "common" directory. The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top. This approach makes the patches a bit
more tractable.
I chose the name "gdbsupport" for the directory. However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.
Tested by the buildbot.

A following patch will introduce options for the "backtrace" command,
based on some "set print" and "set backtrace" settings. There's one
setting in particular that is a bit annoying if we want to describe
the backtrace options and the settings commands using the same data
structures:
"set print raw frame-arguments"
The problem is that space between "raw" and "frame-arguments".
Calling the option
"bt -raw frame-arguments"
would be odd. So I'm calling the option
"bt -raw-frame-arguments"
instead.
And for consistency, this patch renames the set/show commands to:
"set print raw-frame-arguments"
"show print raw-frame-arguments"
I.e., dash instead of space. The old commands are left in place, but
marked deprecated.
We need to adjust a couple testcases, because the relevant tests use
gdb_test_no_output and the old commands are no longer silent:
(gdb) set print raw frame-arguments on
Warning: command 'set print raw frame-arguments' is deprecated.
Use 'set print raw-frame-arguments'.
gdb/ChangeLog:
2019-06-13 Pedro Alves <palves@redhat.com>
* NEWS (Changed commands): Mention set/show print raw-frame-arguments,
and that "set/show print raw frame-arguments" are now deprecated.
* cli/cli-decode.c (add_setshow_boolean_cmd): Now returns the

raw".

This patch adds support for "print -option optval --", etc.
Likewise for "compile print".
We'll get:
~~~~~~
(gdb) help print
Print value of expression EXP.
Usage: print [[OPTION]... --] [/FMT] [EXP]
Options:
-address [on|off]
Set printing of addresses.
-array [on|off]
Set pretty formatting of arrays.
-array-indexes [on|off]
Set printing of array indexes.
-elements NUMBER|unlimited
Set limit on string chars or array elements to print.
"unlimited" causes there to be no limit.
-max-depth NUMBER|unlimited
Set maximum print depth for nested structures, unions and arrays.
When structures, unions, or arrays are nested beyond this depth then they
will be replaced with either '{...}' or '(...)' depending on the language.
Use "unlimited" to print the complete structure.
-null-stop [on|off]
Set printing of char arrays to stop at first null char.
-object [on|off]
Set printing of C++ virtual function tables.
-pretty [on|off]
Set pretty formatting of structures.
-repeats NUMBER|unlimited
Set threshold for repeated print elements.
"unlimited" causes all elements to be individually printed.
-static-members [on|off]
Set printing of C++ static members.
-symbol [on|off]
Set printing of symbol names when printing pointers.
-union [on|off]
Set printing of unions interior to structures.
-vtbl [on|off]
Set printing of C++ virtual function tables.
Note: because this command accepts arbitrary expressions, if you
specify any command option, you must use a double dash ("--")
to mark the end of option processing. E.g.: "print -o -- myobj".
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I want to highlight the comment above about "--".
At first, I thought we could make the print command parse the options,
and if the option wasn't recognized, fallback to parsing as an
expression. Then, if the user wanted to disambiguate, he'd use the
"--" option delimiter. For example, if you had a variable called
"object" and you wanted to print its negative, you'd have to do:
(gdb) print -- -object
After getting that working, I saw that gdb.pascal/floats.exp
regressed, in these tests:
gdb_test "print -r" " = -1\\.2(499.*|5|500.*)"
gdb_test "print -(r)" " = -1.2(499.*|5|500.*)"
gdb_test "print -(r + s)" " = -3\\.4(499.*|5|500.*)"
It's the first one that I found most concerning. It regressed because
"-r" is the abbreviation of "-raw". I realized then that the behavior
change was a bit risker than I'd like, considering scripts, wrappers
around gdb, etc., and even user expectation. So instead, I made the
print command _require_ the "--" options delimiter if you want to
specify any option. So:
(gdb) print -r
is parsed as an expression, and
(gdb) print -r --
is parsed as an option.
I noticed that that's also what lldb's expr (the equivalent of print)
does to handle the same problem.
Going back the options themselves, note that:
- you can shorten option names, as long as unambiguous.
- For boolean options, 0/1 stand for off/on.
- For boolean options, "true" is implied.
So these are all equivalent:
(gdb) print -object on -static-members off -pretty on -- foo
(gdb) print -object -static-members off -pretty -- foo
(gdb) print -object -static-members 0 -pretty -- foo
(gdb) print -o -st 0 -p -- foo
TAB completion is fully supported:
(gdb) p -[TAB]
-address -elements -pretty -symbol
-array -null-stop -repeats -union
-array-indexes -object -static-members -vtbl
Note that the code is organized such that some of the options and the
"set/show" commands code is shared. In particular, the "print"
options and the corresponding "set print" commands are defined with
the same structures. The commands are installed with the
gdb::option::add_setshow_cmds_for_options function.

A user wanted to be able to disable the display of the value when
using "finish" -- but still have the value entered into the value
history in case it was useful later on. Part of the rationale here is
that sometimes the value might be quite large, or expensive to display
(in their case this was compounded by a rogue pretty-printer).
This patch implements this idea.

Introduce a new print setting max-depth which can be set with 'set
print max-depth DEPTH'. The default value of DEPTH is 20, but this
can also be set to unlimited.
When GDB is printing a value containing nested structures GDB will
stop descending at depth DEPTH. Here is a small example:
typedef struct s1 { int a; } s1;
typedef struct s2 { s1 b; } s2;
typedef struct s3 { s2 c; } s3;
typedef struct s4 { s3 d; } s4;
s4 var = { { { { 3 } } } };
The following table shows how various depth settings affect printing
of 'var':
| Depth Setting | Result of 'p var' |
|---------------+--------------------------------|
| Unlimited | $1 = {d = {c = {b = {a = 3}}}} |
| 4 | $1 = {d = {c = {b = {a = 3}}}} |
| 3 | $1 = {d = {c = {b = {...}}}} |
| 2 | $1 = {d = {c = {...}}} |
| 1 | $1 = {d = {...}} |
| 0 | $1 = {...} |
Only structures, unions, and arrays are replaced in this way, scalars
and strings are not replaced.
The replacement is counted from the level at which you print, not from
the top level of the structure. So, consider the above example and
this GDB session:
(gdb) set print max-depth 2
(gdb) p var
$1 = {d = {c = {...}}}
(gdb) p var.d
$2 = {c = {b = {...}}}
(gdb) p var.d.c
$3 = {b = {a = 3}}
Setting the max-depth to 2 doesn't prevent the user from exploring
deeper into 'var' by asking for specific sub-fields to be printed.
The motivation behind this feature is to try and give the user more
control over how much is printed when examining large, complex data
structures.
The default max-depth of 20 means that there is a change in GDB's
default behaviour. Someone printing a data structure with 20 levels
of nesting will now see '{...}' instead of their data, they would need
to adjust the max depth, or call print again naming a specific field
in order to dig deeper into their data structure. If this is
considered a problem then we could increase the default, or even make
the default unlimited.
This commit relies on the previous commit, which added a new field to
the language structure, this new field was a string that contained the
pattern that should be used when a structure/union/array is replaced
in the output, this allows languages to use a syntax that is more
appropriate, mostly this will be selecting the correct types of
bracket '(...)' or '{...}', both of which are currently in use.
This commit should have no impact on MI output, expressions are
printed through the MI using -var-create and then -var-list-children.
As each use of -var-list-children only ever displays a single level of
an expression then the max-depth setting will have no impact.
This commit also adds the max-depth mechanism to the scripting
language pretty printers following basically the same rules as for the
built in value printing.
One quirk is that when printing a value using the display hint 'map',
if the keys of the map are structs then GDB will hide the keys one
depth level after it hides the values, this ensures that GDB produces
output like this:
$1 = map_object = {[{key1}] = {...}, [{key2}] = {...}}
Instead of this less helpful output:
$1 = map_object = {[{...}] = {...}, [{...}] = {...}}
This is covered by the new tests in gdb.python/py-nested-maps.exp.

This renames the gdb exception types. The old types were only needed
due to the macros in common-exception.h that are now gone.
The intermediate layer of gdb_exception_RETURN_MASK_ALL did not seem
needed, so this patch removes it entirely.

A customer noticed some mildly odd MI output, where CLI output was
split into multiple MI strings at unusual boundaries, like this:
~"$1 = (b => true"
~", p => 0x407260"
This is technically correct according to the MI spec, but still
unusual, in that there's no particular reason for the string to be
split where it is.
I tracked this down to a call to gdb_flush in generic_val_print.
Then, I went through all calls to gdb_flush and removed the ones I
thought were superfluous. In particular:
* Any call in the value-printing code;
* Likewise the type-printing code (just a single call); and
* Any call that immediately followed a printf that obviously
ended with a newline, my belief being that gdb's standard output
streams are line buffered (by inheriting the behavior from stdio)
Regression tested on x86-64 Fedora 29.
I didn't add a new test case. I tend to think we don't necessarily
want to specify this behavior in the tests. Let me know what you
think of this.

This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
gdb/ChangeLog:
Update copyright year range in all GDB files.

I encountered a binary compiled with Intel's C Compiler (ICC) version
14.0.5.212, which seemed to contain some non-standard DWARF.
The DWARF spec (V5 3.3.2) says:
Debugging information entries for C void functions should not have
an attribute for the return type.
However, what I observed in the DWARF from this ICC compiled binary
was this:

<803> DW_AT_low_pc : 0x4378a0

<813> DW_AT_external : 1
...
So function 'function_foo' has void return type, but still has a
DW_AT_type attribute for a 0 sized type called void.
What was found was that when the 'finish' command was used to leave
'function_foo', GDB would crash.
The problem is that in infcmd.c:print_return_value GDB tries to filter
out void return types, by looking for the TYPE_CODE_VOID, this fails
for the 'void' type as it has code TYPE_CODE_INT and GDB then tries to
print the 'void' type.
This eventually ends in a call to valprint.c:maybe_negate_by_bytes,
however, the len (length) of the value being negated is 0, which is
not detected or expected by this code, and invalid memory accesses
occur, some of which might cause GDB to crash.
The above DWARF was seen on version 14.0.5.212 of ICC.
I have also tested ICC versions 18.0.2.199 and 17.0.7.259, on both of
these versions, the DW_AT_type on the DW_TAG_subprogram has been
removed, bringing ICC inline with the DWARF standard, and with the
DWARF produced by GCC.
I only have limited access to these specific versions of ICC so I am
unable to get more specific details for when the generated DWARF
became non-standard or when it was changed to be more inline with the
DWARF standard.
Further testing revealed additional places where ICC produced 'void'
related DWARF that GDB struggles with. When I compiled code that
contained a function with this signature:
void funcx (void *arg);
on ICC 17/18, I got the following DWARF (notice the void return type
is now gone):
...
<1><32>: Abbrev Number: 2 (DW_TAG_subprogram)
<33> DW_AT_decl_line : 2
<34> DW_AT_decl_file : 1
<35> DW_AT_prototyped : 1
<36> DW_AT_name : (indirect string, offset: 0xc5): funcx
<3a> DW_AT_MIPS_linkage_name: (indirect string, offset: 0xc5): funcx
<3e> DW_AT_low_pc : 0x6dc
<46> DW_AT_high_pc : 0x703
<4e> DW_AT_external : 1
<2><4f>: Abbrev Number: 3 (DW_TAG_formal_parameter)
<50> DW_AT_decl_line : 2
<51> DW_AT_decl_file : 1
<52> DW_AT_type : <0x6a>
<56> DW_AT_name : arg
<5a> DW_AT_location : 2 byte block: 76 70 (DW_OP_breg6 (rbp): -16)
...
<1><6a>: Abbrev Number: 5 (DW_TAG_pointer_type)
<6b> DW_AT_type : <0x6f>
<1><6f>: Abbrev Number: 6 (DW_TAG_base_type)
<70> DW_AT_byte_size : 0
<71> DW_AT_encoding : 5 (signed)
<72> DW_AT_name : (indirect string, offset: 0xcb): void
...
However, the function argument 'arg' does still reference a 'void'
type. This case doesn't seem as obviously non-standard as the
previous one, but I think that the DWARF standard (V5 5.2) does
suggest that the above is not the recommended approach. If we compare
to the DWARF generated by GCC 7.3.1:
...
<1><68>: Abbrev Number: 5 (DW_TAG_subprogram)
<69> DW_AT_external : 1
<69> DW_AT_name : (indirect string, offset: 0x221): funcx
<6d> DW_AT_decl_file : 1
<6e> DW_AT_decl_line : 2
<6f> DW_AT_prototyped : 1
<6f> DW_AT_low_pc : 0x400487
<77> DW_AT_high_pc : 0x22
<7f> DW_AT_frame_base : 1 byte block: 9c (DW_OP_call_frame_cfa)
<81> DW_AT_GNU_all_call_sites: 1
<81> DW_AT_sibling : <0xa0>
<2><85>: Abbrev Number: 6 (DW_TAG_formal_parameter)
<86> DW_AT_name : arg
<8a> DW_AT_decl_file : 1
<8b> DW_AT_decl_line : 2
<8c> DW_AT_type : <0xa0>
<90> DW_AT_location : 2 byte block: 91 58 (DW_OP_fbreg: -40)
...
<1><a0>: Abbrev Number: 7 (DW_TAG_pointer_type)
<a1> DW_AT_byte_size : 8
...
Here we see that the DW_TAG_pointer_type doesn't reference any further
type. This also seems out of line with the DWARF standard (which I
think recommends using a DW_TAG_unspecified_type entry), however GDB
does handle the GCC generated DWARF better.
If we look at how GDB handles the DWARF from GCC, then we see this:
(gdb) print *arg
Attempt to dereference a generic pointer.
While on the current HEAD of master dereferencing arg causes undefined
behaviour which will likely crash GDB (for the same reason as was
described above for the 'finish' case). On earlier versions of GDB
the ICC DWARF would cause this:
(gdb) print *arg
$1 = 0
In this patch both the return type, and general variable/parameter
type handling is fixed by transforming the synthetic void entries in
the DWARF, the ones that look like this:
<1><6f>: Abbrev Number: 6 (DW_TAG_base_type)
<70> DW_AT_byte_size : 0
<71> DW_AT_encoding : 5 (signed)
<72> DW_AT_name : (indirect string, offset: 0xcb): void
into GDB's builtin void type. My criteria for performing the fix are:
1. Binary produced by any version of ICC,
2. We're producing an integer type,
3. The size is 0, and
4. The name is "void".
I ignore the signed / unsigned nature of the integer.
Potentially we could drop the ICC detection too, this should be a
reasonably safe transformation to perform, however, I'm generally
pretty nervous when it comes to modifying how the DWARF is parsed so,
for now, I have restricted this to ICC only.
I also added an assertion to maybe_negate_by_bytes. This is nothing
to do with the actual fix, but should detect incorrect use of this
function in the future, without relying on undefined behaviour to
crash GDB.
I added a new test that makes use the of the testsuite's DWARF
generator. As it is tricky to create target independent tests that
pass function parameters using the DWARF generator (as specifying the
argument location is target specific) I have instead made use of a
global variable void*. This still shows the issue.
We already have a predicate in the DWARF parser to detect versions of
ICC prior to 14, however, this issue was spotted on a later version.
As a result I've added a new predicate that is true for any version of
ICC.

This fixes all the straightforward -Wshadow=local warnings in gdb. A
few standard approaches are used here:
* Renaming an inner (or outer, but more commonly inner) variable;
* Lowering a declaration to avoid a clash;
* Moving a declaration into a more inner scope to avoid a clash,
including the special case of moving a declaration into a loop header.
I did not consider any of the changes in this patch to be particularly
noteworthy, though of course they should all still be examined.

The recent C++ification of target_ops replaced references to the old
"current_target" squashed target throughout with references to a
"target_stack" pointer. I had picked the "target_stack" name very
early in the multi-target work, and managed to stick with it, even
though it's a bit of a misnomer, since it isn't really a "target
stack" object, but a pointer into the current top target in the stack.
As I'm splitting more pieces off of the multi-target branch, I've come
to think that it's better to rename it now. A following patch will
introduce a new class to represent a target stack, and "target_stack"
would be _its_ ideal name. (In the branch, the class is called
a_target_stack to work around the clash.)
Thus this commit renames target_stack to current_top_target and
replaces all references throughout. Also, while at it,
current_top_target is made a function instead of a pointer, to make it
possible to change its internal implementation without leaking
implementation details out. In a couple patches, the implementation
of the function will change to refer to a target stack object, and
then further down the multi-target work, it'll change again to find
the right target stack for the current inferior.

I.e., use C++ virtual methods and inheritance instead of tables of
function pointers.
Unfortunately, there's no way to do a smooth transition. ALL native
targets in the tree must be converted at the same time. I've tested
all I could with cross compilers and with help from GCC compile farm,
but naturally I haven't been able to test many of the ports. Still, I
made a best effort to port everything over, and while I expect some
build problems due to typos and such, which should be trivial to fix,
I don't expect any design problems.
* Implementation notes:
- The flattened current_target is gone. References to current_target
or current_target.beneath are replaced with references to
target_stack (the top of the stack) directly.
- To keep "set debug target" working, this adds a new debug_stratum
layer that sits on top of the stack, prints the debug, and delegates
to the target beneath.
In addition, this makes the shortname and longname properties of
target_ops be virtual methods instead of data fields, and makes the
debug target defer those to the target beneath. This is so that
debug code sprinkled around that does "if (debugtarget) ..." can
transparently print the name of the target beneath.
A patch later in the series actually splits out the
shortname/longname methods to a separate structure, but I preferred
to keep that chance separate as it is associated with changing a bit
the design of how targets are registered and open.
- Since you can't check whether a C++ virtual method is overridden,
the old method of checking whether a target_ops implements a method
by comparing the function pointer must be replaced with something
else.
Some cases are fixed by adding a parallel "can_do_foo" target_ops
methods. E.g.,:
+ for (t = target_stack; t != NULL; t = t->beneath)
{
- if (t->to_create_inferior != NULL)
+ if (t->can_create_inferior ())
break;
}
Others are fixed by changing void return type to bool or int return
type, and have the default implementation return false or -1, to
indicate lack of support.
- make-target-delegates was adjusted to generate C++ classes and
methods.
It needed tweaks to grok "virtual" in front of the target method
name, and for the fact that methods are no longer function pointers.
(In particular, the current code parsing the return type was simple
because it could simply parse up until the '(' in '(*to_foo)'.
It now generates a couple C++ classes that inherit target_ops:
dummy_target and debug_target.
Since we need to generate the class declarations as well, i.e., we
need to emit methods twice, we now generate the code in two passes.
- The core_target global is renamed to avoid conflict with the
"core_target" class.
- ctf/tfile targets
init_tracefile_ops is replaced by a base class that is inherited by
both ctf and tfile.
- bsd-uthread
The bsd_uthread_ops_hack hack is gone. It's not needed because
nothing was extending a target created by bsd_uthread_target.
- remote/extended-remote targets
This is a first pass, just enough to C++ify target_ops.
A later pass will convert more free functions to methods, and make
remote_state be truly per remote instance, allowing multiple
simultaneous instances of remote targets.
- inf-child/"native" is converted to an actual base class
(inf_child_target), that is inherited by all native targets.
- GNU/Linux
The old weird double-target linux_ops mechanism in linux-nat.c, is
gone, replaced by adding a few virtual methods to linux-nat.h's
target_ops, called low_XXX, that the concrete linux-nat
implementations override. Sort of like gdbserver's
linux_target_ops, but simpler, for requiring only one
target_ops-like hierarchy, which spares implementing the same method
twice when we need to forward the method to a low implementation.
The low target simply reimplements the target_ops method directly in
that case.
There are a few remaining linux-nat.c hooks that would be better
converted to low_ methods like above too. E.g.:
linux_nat_set_new_thread (t, x86_linux_new_thread);
linux_nat_set_new_fork (t, x86_linux_new_fork);
linux_nat_set_forget_process
That'll be done in a follow up patch.
- We can no longer use functions like x86_use_watchpoints to install
custom methods on an arbitrary base target.
The patch replaces instances of such a pattern with template mixins.
For example memory_breakpoint_target defined in target.h, or
x86_nat_target in x86-nat.h.
- linux_trad_target, MIPS and Alpha GNU/Linux
The code in the new linux-nat-trad.h/c files which was split off of
inf-ptrace.h/c recently, is converted to a C++ base class, and used
by the MIPS and Alpha GNU/Linux ports.
- BSD targets
The
$architecture x NetBSD/OpenBSD/FreeBSD
support matrix complicates things a bit. There's common BSD target
code, and there's common architecture-specific code shared between
the different BSDs. Currently, all that is stiched together to form
a final target, via the i386bsd_target, x86bsd_target,
fbsd_nat_add_target functions etc.
This introduces new fbsd_nat_target, obsd_nat_target and
nbsd_nat_target classes that serve as base/prototype target for the
corresponding BSD variant.
And introduces generic i386/AMD64 BSD targets, to be used as
template mixin to build a final target. Similarly, a generic SPARC
target is added, used by both BSD and Linux ports.
- bsd_kvm_add_target, BSD libkvm target
I considered making bsd_kvm_supply_pcb a virtual method, and then
have each port inherit bsd_kvm_target and override that method, but
that was resulting in lots of unjustified churn, so I left the
function pointer mechanism alone.

This adds target_float_to_string and target_float_from_string,
which dispatch to the corresponding floatformat_ or decimal_ routines.
Existing users of those routines are changed to use the new
target-float routines instead (most of those places already handle
both binary and decimal FP).
In addition, two other places are changes to use target_float_from_string:
- define_symbol in stabsread.c, when parsing a floating-point literal
from stabs debug info
- gdbarch-selftest.c when initializing a target format values (to
eliminate use of DOUBLEST there).

The print_floating routine currently makes a lot of assumptions about host
and target floating point formats. This patch cleans up many of those.
One problem is that print_floating may currently be called with types
that are not actually floating-point types, and it tries hard to output
those as floating-point values anyway. However, there is only one single
caller of print_floating where this can ever happen: print_scalar_formatted.
And in fact, it is much simpler to handle the case where the value to be
printed is not already of floating-point type right there.
So this patch changes print_scalar_formatted to handle the 'f' format
as follows:
- If the value to be printed is already of floating-point type, just
call print_floating on it.
- Otherwise, if there is a standard target floating-point type of
the same size as the value, call print_floating using that type.
- Otherwise, just print the value as if the 'f' format had not been
specified at all.
This has the overall effect to printing everything the same way as
the old code did, but is overall a lot simpler. (Also, it would
allow us to change the above strategy more easily, if that might
be a more intuitive user interface. For example, in the third
case above, maybe an error would be more appropriate?)
Given that change, print_floating can become much simpler. In particular,
we now always have a floating-point format that we can consult. This
means we can use the floating-point format to programmatically determine
the number of digits necessary to print the value.
The current code uses a hard-coded value of 9, 17, or 35 digits. Note
that this matches the DECIMAL_DIG values for IEEE-32, IEEE-64, and
IEEE-128. (Actually, for IEEE-128 the correct value is 36 -- the 35
seems to be an oversight.) The DECIMAL_DIG value is defined to be
the smallest number so that any number in the target format, when
printed to this number of digits and then scanned back into a binary
floating-point number, will result in the original value.
Now that we always have a FP format, we can just compute the DECIMAL_DIG
value using the formula from the C standard. This will be correct for
*all* FP formats, not just the above list, and it will be correct (as
opposed to current code) if the target formats differ from the host ones.
The patch moves the new logic to a new floatformat_to_string routine
(analogous to the existing decimal_to_string). The print_floating
routine now calls floatformat_to_string or decimal_to_string, making
the separate print_decimal_floating and generic_val_print_decfloat routines
unnecessary.

This changes add_prefix_cmd to accept a const-taking function as an
argument; then fixes up all the callers.
In a couple of spots I had to add a non-const overload of a function,
because the function is passed to two different command-adding
"constructors". These overloads are temporary; once constification is
complete they can be removed.
This patch also fixes a typo I happened to notice while constifying.
Note that this touches a couple of files (gnu-nat.c and go32-nat.c)
that I can't build. So, while I made a best-effort there, I am not
certain they will still compile.
Tested by rebuilding.

This cleans up a number of interfaces in dfp.c / dfp.h. Specifically:
- The decimal_from_string / decimal_to_string routines are C++-ified
to operate on std::string instead of character buffers. In the
decimal_from_string, the boolean return value now actually is bool
instead of an int.
- The decimal_from_integral and decimal_from_doublest routines take
an struct value as input. This is not really appropriate at the low
level the DFP routines sit, so this replaced them with new routines
decimal_from_longest / decimal_from_ulongest / decimal_from_doublest
that operate on contents instead.
- To mirror the decimal_from_[u]longest, a new decimal_to_longest
routine is added as well, which can be used in unpack_long to
avoid an unnecessary conversion via DOUBLEST.
Note that the decimal_from_longest / decimal_from_ulongest routines
are actually more powerful than decimal_from_integral: the old routine
would only accept integer *types* of at most four bytes size, while
the new routines accept all integer *values* that fit in an [u]int32_t,
no matter which type they came from. The DFP tests are updated to
allow for this larger range of integers that can be converted.

PR gdb/21675 points out a few regressions in scalar printing.
One type of regression is due to not carrying over the old handling of
floating point printing -- where a format like "/d" causes a floating
point number to first be cast to a signed integer. This patch restores
this behavior.
The other regression is a longstanding bug in print_octal_chars: one of
the constants was wrong. This patch fixes the constant and adds static
asserts to help catch this sort of error.

This commit eliminates make_cleanup_obstack_free, replacing it with a
new auto_obstack type that inherits obstack to add cdtors.
These changes in the parsers may not be obvious:
- obstack_init (&name_obstack);
- make_cleanup_obstack_free (&name_obstack);
+ name_obstack.clear ();
Here, the 'name_obstack' variable is a global. The change means that
the obstack's contents from a previous parse will stay around until
the next parsing starts. I.e., memory won't be reclaimed until then.
I don't think that's a problem, these objects don't really grow much
at all.
The other option I tried was to add a separate type that is like
auto_obstack but manages an external obstack, just for those cases. I
like the current approach better as that other approach adds more
boilerplate and yet another type to learn.

In some cases we've been replacing heap-allocated gdb_byte buffers
managed with xmalloc/make_cleanup(xfree) with gdb::vector<gdb_byte>.
That usually pessimizes the code a little bit because std::vector
value-initializes elements (which for gdb_byte means
zero-initialization), while if you're creating a temporary buffer,
you're most certaintly going to fill it in with some data. An
alternative is to use
unique_ptr<gdb_byte[]> buf (new gdb_byte[size]);
but it looks like that's not very popular.
Recently, a use of obstacks in dwarf2read.c was replaced with
std::vector<gdb_byte> and that as well introduced a pessimization for
always memsetting the buffer when it's garanteed that the zeros will
be overwritten immediately. (see dwarf2read.c change in this patch to
find it.)
So here's a different take at addressing this issue "by design":
#1 - Introduce default_init_allocator<T>
I.e., a custom allocator that does default construction using default
initialization, meaning, no more zero initialization. That's the
default_init_allocation<T> class added in this patch.
See "Notes" at
<http://en.cppreference.com/w/cpp/container/vector/resize>.
#2 - Introduce def_vector<T>
I.e., a convenience typedef, because typing the allocator is annoying:
using def_vector<T> = std::vector<T, gdb::default_init_allocator<T>>;
#3 - Introduce byte_vector
Because gdb_byte vectors will be the common thing, add a convenience
"byte_vector" typedef:
using byte_vector = def_vector<gdb_byte>;
which is really the same as:
std::vector<gdb_byte, gdb::default_init_allocator<gdb_byte>>;
The intent then is to make "gdb::byte_vector" be the go-to for dynamic
byte buffers. So the less friction, the better.
#4 - Adjust current code to use it.
To set the example going forward. Replace std::vector uses and also
unique_ptr<byte[]> uses.
One nice thing is that with this allocator, for changes like these:
-std::unique_ptr<byte[]> buf (new gdb_byte[some_size]);
+gdb::byte_vector buf (some_size);
fill_with_data (buf.data (), buf.size ());
the generated code is the same as before. I.e., the compiler
de-structures the vector and gets rid of the unused "reserved vs size"
related fields.
The other nice thing is that it's easier to write
gdb::byte_vector buf (size);
than
std::unique_ptr<gdb_byte[]> buf (new gdb_byte[size]);
or even (C++14):
auto buf = std::make_unique<gdb_byte[]> (size); // zero-initializes...
#5 - Suggest s/std::vector<gdb_byte>/gdb::byte_vector/ going forward.
Note that this commit actually fixes a couple of bugs where the current
code is incorrectly using "std::vector::reserve(new_size)" and then
accessing the vector's internal buffer beyond the vector's size: see
dwarf2loc.c and charset.c. That's undefined behavior and may trigger
debug mode assertion failures. With default_init_allocator,
"resize()" behaves like "reserve()" performance wise, in that it
leaves new elements with unspecified values, but, it does that safely
without triggering undefined behavior when you access those values.

val_print_scalar_formatted.

In almost all contexts (except for overload resolution rules and expression
semantics), lvalue and rvalue references are equivalent. That means that in all
but these cases we can replace a TYPE_CODE_REF check to a TYPE_IS_REFERENCE
check and, for switch statements, add a case label for a rvalue reference type
next to a case label for an lvalue reference type. This patch does exactly
that.

Resyncing due to internal error.
This internal error is caused by e8b24d9 (Remove parameter valaddr from
la_val_print). Commit e8b24d9 removes some calls to
value_contents_for_printing, but value_fetch_lazy is not called, so the
internal error above is triggered. This patch adds value_fetch_lazy

Nowadays, we pass both val and return value of
value_contents_for_printing (val) to la_val_print. The latter is
unnecessary. This patch removes the second parameter of la_val_print,
and get valaddr in each language's implementation by calling
value_contents_for_printing. Since value_contents_for_printing calls
value_fetch_lazy, I also make VAL non-const.
Note that
- I don't clean up the valaddr usages in each language's routines,
- I don't remove valaddr from apply_ext_lang_val_pretty_printer, and
extension language ops apply_val_pretty_printer.
They can be done in followup patches.

Now that init_type no longer takes a FLAGS argument, there is no user of

references to them in comments as well).
This is mostly a no-op, except for a change to the Python type printer,

really needed anyway, since it was only used to pretty-print type
