When calling the language la_print_typedef method, don't include a
newline at the end, instead print the newline from the users of
la_print_typedef.
This change will be useful in a later commit when the output from
la_print_typedef will be placed into an MI output field, in which case
the trailing newline is not required.
There should be no user visible changes after this commit.

This patch adds two new commands "info module functions" and "info
module variables". These commands list all of the functions and
variables grouped by module and then by file.
For example:
(gdb) info module functions
All functions in all modules:
Module "mod1":
File /some/path/gdb/testsuite/gdb.fortran/info-types.f90:
35: void mod1::__copy_mod1_M1t1(Type m1t1, Type m1t1);
25: void mod1::sub_m1_a(integer(kind=4));
31: integer(kind=4) mod1::sub_m1_b(void);
Module "mod2":
File /some/path/gdb/testsuite/gdb.fortran/info-types.f90:
41: void mod2::sub_m2_a(integer(kind=4), logical(kind=4));
49: logical(kind=4) mod2::sub_m2_b(real(kind=4));
The new commands take set of flags that allow the output to be
filtered, the user can filter by variable/function name, type, or
containing module.
As GDB doesn't currently track the relationship between a module and
the variables or functions within it in the symbol table, so I filter
based on the module prefix in order to find the functions or variables
in each module. What this makes clear is that a user could get this
same information using "info variables" and simply provide the prefix
themselves, for example:
(gdb) info module functions -m mod1 _a
All functions matching regular expression "_a",
in all modules matching regular expression "mod1":
Module "mod1":
File /some/path/gdb/testsuite/gdb.fortran/info-types.f90:
25: void mod1::sub_m1_a(integer(kind=4));
Is similar to:
(gdb) info functions mod1::.*_a.*
All functions matching regular expression "mod1::.*_a":
File /some/path/gdb/testsuite/gdb.fortran/info-types.f90:
25: void mod1::sub_m1_a(integer(kind=4));
The benefits I see for a separate command are that the user doesn't
have to think (or know) about the module prefix format, nor worry
about building a proper regexp. The user can also easily scan across
modules without having to build complex regexps.
The new function search_module_symbols is extern in this patch despite
only being used within symtab.c, this is because a later patch in this
series will also be using this function from outside symtab.c.
This patch is a new implementation of an idea originally worked on by
Mark O'Connor, Chris January, David Lecomber, and Xavier Oro from ARM.

Add a new command 'info modules' that lists all of the modules GDB
knows about from the debug information.
A module is a debugging entity in the DWARF defined with
DW_TAG_module, currently Fortran is known to use this tag for its
modules. I'm not aware of any other language that currently makes use
of DW_TAG_module.
The output style is similar to the 'info type' output:
(gdb) info modules
All defined modules:
File info-types.f90:
16: mod1
24: mod2
(gdb)
Where the user is told the file the module is defined in and, on the
left hand side, the line number at which the module is defined along
with the name of the module.

Mark O'Connor, Chris January, David Lecomber, and Xavier Oro from ARM.

Just some code cleanup. This change has a few benefits:
- Shorter argument list in the functions
- If the caller needs to calculate the string, they no longer
need to explicitly call strlen
- It is easy to pass std::string to this (done in one place
currently)
This also updates a couple of places that were passing 0/1 to
a bool parameter.

As of 7bb43059820c5febb4509b15202a93efde442bc6, we no longer need
a nullterminated linkage_name to look up the entry in the hash table.
So this patch makes it so we only make the copy if the entry was
not found.
By auditing all callers of symbol_set_names, I found out that all cases
where the string may not be nullterminated already pass true for COPY_NAME.
So here, I am documenting that as a requirement and am removing the code
that relies on undefined behavior in symbol_set_names (it accessed the string
past the provided length to check for nulltermination). Note that the Ada
case at the beginning of symbol_set_names was already relying on this.

I run into this error with gdb.base/fullname.exp:
...

Make breakpoint pending on future shared library load? (y or [n]) n
(gdb) FAIL: gdb.base/fullname.exp: set breakpoint by full path before loading symbols - built relative
...
The FAIL is due to this comparison in iterate_over_some_symtabs failing:
...
481 if (FILENAME_CMP (real_path, fullname) == 0)
(gdb) p real_path
$2 = 0x1a201f0 "/data/gdb_versions/devel/build/gdb/testsuite/outputs/\

(gdb) p fullname
$3 = 0x1a1de80 "/home/vries/gdb_versions/devel/build/gdb/testsuite/outputs/\
gdb.base/fullname/tmp-fullname.c"
...
The difference in pathnames is due to having a symlink dir:
...
$ ls -la /home/vries/gdb_versions
lrwxrwxrwx 1 vries users 18 26 jun 2018 /home/vries/gdb_versions -> /data/gdb_versions
...
and the test passses when eliminating it:
...
$ ( cd $(pwd -P); make check RUNTESTFLAGS=gdb.base/fullname.exp )
...
The FAIL is a regression from commit a0c1ffedcf1 "Only compute realpath when
basenames_may_differ is set". Before, find_and_open_source was returning a
real-path, resulting in variable 'fullname' being the same as varible
'real_path' in the comparison listed above. But after, that's no longer the
case.
Fix the FAIL by applying gdb_realpath on the fullname variable before the
comparison.
Tested on x86_64-linux.
I wasn't able to write a test-case. The FAIL starts at:
...
$ cd build/gdb
$ mv testsuite testsuite.bla
$ ln -s testsuite.bla testsuite
...
but already this doesn't trigger it anymore:
...
$ cd build/gdb/outputs
$ mv outputs outputs.bla
$ ln -s outputs.bla outputs
...

In ELF, if a data symbol is defined in a shared library and used by
the main program, it will be subject to a "copy relocation". In this
scenario, the main program has a copy of the symbol in question, and a
relocation that tells ld.so to copy the data from the shared library.
Then the symbol in the main program is used to satisfy all references.
This patch changes gdb to handle this scenario. Data symbols coming
from ELF shared libraries get a special flag that indicates that the
symbol's address may be subject to copy relocation.
I looked briefly into handling copy relocations by looking at the
actual relocations in the main program, but this seemed difficult to
do with BFD.
Note that no caching is done here. Perhaps this could be changed if
need be; I wanted to avoid possible problems with either objfile
lifetimes and changes, or conflicts with the long-term (vapor-ware)
objfile splitting project.

This changes lookup_global_symbol to look in the global block
of the passed-in block. If no block was passed in, it reverts to the
previous behavior.
This change is needed to ensure that 'FILENAME'::NAME lookups work
properly. As debugging Pedro's test case showed, this was not working
properly in the case where multiple identical names could be found
(the one situation where this feature is truly needed :-).
This also removes some old comments from basic_lookup_symbol_nonlocal
that no longer apply.
Note that the new test cases for this change will appear in a later
patch. They are in gdb.base/print-file-var.exp.

All implementations of either function use it for the same purpose (except
Darwin, which is a no-op): to prefer a symbol in the current objfile over
symbols with the same name in other objfiles. There does not seem to be a

This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

This parameter is really a boolean, so change the type accordingly
and update the callers.
This is for symbol_set_names, add_psymbol_to_bcache, and
add_psymbol_to_list.
minimal_symbol_reader::record_full was already passing a bool
to symbol_set_names.

Currently the 'info types' command will return symbols that correspond
to Fortran modules. This is because the symbols are created with
domain MODULE_DOMAIN and address_class LOC_TYPEDEF. The address_class
LOC_TYPEDEF is the same address_class used for type symbols which is
why the modules show up when listing types.
This commit explicitly prevents symbols in the MODULE_DOMAIN from
appearing when we search for symbols in the TYPES_DOMAIN, this
prevents the Fortran module symbols from appearing in the output of
'info types'.
gdb/ChangeLog:
* symtab.c (search_symbols): Don't include MODULE_DOMAIN symbols

The 'info variables', its alias 'whereis', and 'info functions' all
include non-debug symbols in the output by default. The list of
non-debug symbols can sometimes be quite long, resulting in the
debug symbol based results being scrolled off the screen.
This commit adds a '-n' flag to all of the commands listed above that
excludes the non-debug symbols from the results, leaving just the
debug symbol based results.

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).

This commit makes two changes to the "info types" command:
First, only use typedef_print for printing typedefs, and use
type_print for printing non-typedef scalar (non-struct) types. The
result of this is the output for builtin types goes from this:
typedef double;
typedef float;
typedef int;
to this:
double;
float;
int;
which seems to make more sense.
Next GDB no longer matches msymbols as possible type names. When
looking for function symbols it makes sense to report matching
msymbols from the text sections, and for variables msymbols from the
data/bss sections, but when reporting types GDB would match msymbols
of type absolute. But I don't see why these are likely to indicate
type names. As such I've updated the msymbol matching lists in
symtab.c:search_symbols so that when searching in the TYPES_DOMAIN, we
never match any msymbols.
gdb/ChangeLog:
* symtab.c (search_symbols): Adjust msymbol matching type arrays
so that GDB doesn't match any msymbols when searching in the
TYPES_DOMAIN.
(print_symbol_info): Print using typedef_print or type_print based
on the type of the symbol. Add updated FIXME comment moved from...
(_initialize_symtab): ... move and update FIXME comment to above.

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.

It was observed that in some cases, placing a breakpoint in an
assembler file using filename:line-number syntax would result in the
breakpoint being placed at a different line within the file.
For example, consider this x86-64 assembler:
test:
push %rbp /* Break here. */
mov %rsp, %rbp
nop /* Stops here. */
The user places the breakpoint using file:line notation targeting the
line marked 'Break here', GDB actually stops at the line marked 'Stops
here'.
The reason is that the label 'test' is identified as the likely start
of a function, and the call to symtab.c:skip_prologue_sal causes GDB
to skip forward over the instructions that GDB believes to be part of
the prologue.
I believe however, that when debugging assembler code, where the user
has instruction-by-instruction visibility, if they ask for a specific
line, GDB should (as far as possible) stop on that line, and not
perform any prologue skipping. I don't believe that the behaviour of
higher level languages should change, in these cases skipping the
prologue seems like the correct thing to do.
In order to implement this change I needed to extend our current
tracking of when the user has requested an explicit line number. We
already tracked this in some cases, but not in others (see the changes
in linespec.c). However, once I did this I started to see some
additional failures (in tests gdb.base/break-include.exp
gdb.base/ending-run.exp gdb.mi/mi-break.exp gdb.mi/mi-reverse.exp
gdb.mi/mi-simplerun.exp) where we currently expected a breakpoint
placed at one file and line number to be updated to reference a
different line number, this was fixed by removing some code in
symtab.c:skip_prologue_sal. My concern here is that removing this
check didn't cause anything else to fail.
I have a new test that covers my original case, this is written for
x86-64 as most folk have access to such a target, however, any
architecture that has a prologue scanner can be impacted by this
change.
gdb/ChangeLog:
* linespec.c (decode_digits_list_mode): Set explicit_line to a
bool value.
(decode_digits_ordinary): Set explicit_line field in sal.
* symtab.c (skip_prologue_sal): Don't skip prologue for a
symtab_and_line that was set on an explicit line number in
assembler code. Do always update the recorded symtab and line if
we do skip the prologue.
gdb/testsuite/ChangeLog:
* gdb.arch/amd64-break-on-asm-line.S: New file.
* gdb.arch/amd64-break-on-asm-line.exp: New file.

The commit "[gdb/symtab] Fix language of duplicate static minimal symbol"
introduces a performance regression, when loading a cc1 executable build with
-O0 -g and gcc 7.4.0. The performance regression, measured in 'real' time is
about 175%.
The slower execution comes from the fact that the fix in symbol_set_names
makes the call to symbol_find_demangled_name unconditional.
Fix this by reverting the commit, and redoing the fix as follows.
Recapturing the original problem, the first time symbol_set_names is called
with gsymbol.language == lang_auto and linkage_name == "_ZL3foov", the name is
not present in the per_bfd->demangled_names_hash hash table, so
symbol_find_demangled_name is called to demangle the name, after which the
mangled/demangled pair is added to the hashtable. The call to
symbol_find_demangled_name also sets gsymbol.language to lang_cplus.
The second time symbol_set_names is called with gsymbol.language == lang_auto
and linkage_name == "_ZL3foov", the name is present in the hash table, so the
demangled name from the hash table is used. However, the language of the
symbol remains lang_auto.
Fix this by adding a field language in struct demangled_name_entry, and using
the field in symbol_set_names to set the language of gsymbol, if necessary.
Tested on x86_64-linux.
