gdb/ChangeLog:
Update copyright year range in all GDB files.

Also renames the member variable to m_language to make code easier to read
when more functions become member functions.
I was originally hoping to eventually make m_language private (after a few
more patches), but unfortunately then it no longer counts as a POD type,
which means gdbsupport/poison.h won't let us use memset to initialize
this type, which psymtabs rely on to clear padding bytes so that bcache
can work properly.

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.

Future commits will add more Fortran specific expression operators.
In preparation for these new operators, this commit adds a new
fortran-operator.def file similar to how GDB already has
ada-operator.def.
I've moved UNOP_KIND the Fortran specific operator I introduced in
commit 4d00f5d8f6c4 into this file, and renamed it to make it clearer
that the operator is Fortran specific. I've then updated the Fortran
exp_descriptor table (exp_descriptor_f) to use entirely Fortran
specific functions that now handle UNOP_FORTRAN_KIND (the new name for
UNOP_KIND).
There should be no visible changes for standard users after this
commit, though for developers, the output when 'set debug expression
1' is now better, before:

This replaces throw_exception with "throw;" when possible. This was
written by script. The rule that is followed is that uses of the
form:
catch (... &name)
{
...
throw_exception (name);
}
... can be rewritten. This should always be safe, because exceptions
are caught by const reference, and therefore can't be modified in the
body of the catch.

This introduces a new "type_stack" class, and moves all the parser
type stack handling to this class. Parsers that wish to use this
facility must now instantiate this class somehow. I chose this

This removes the "paren_depth" global. In most cases, it is made into
a static global in a given parser. I consider this a slight
improvement, because it makes it clear that the variable isn't used
for communication between different modules of gdb. The one exception
is the Rust parser, which already incorporates all local state into a
transient object; in this case the parser depth is now a member.

I ran across a comment in symfile.c today:
/* Clear globals which might have pointed into a removed objfile.
FIXME: It's not clear which of these are supposed to persist
between expressions and which ought to be reset each time. */
It seems to me that this can be clarified: the parser entry points
ought to reset the innermost block tracker (and the expression context
block), and these should not be considered valid for code to use at
arbitrary times -- only immediately after an expression has been
parsed.
This patch implements this idea. This could be further improved by
removing the parser globals and changing the parser functions to
return this information, but I have not done this.
Tested by the buildbot.

The 'kind' keyword has two uses in Fortran, it is the name of a
builtin intrinsic function, and it is also a keyword used to create a
type of a specific kind.
This commit adds support for using kind as an intrinsic function, and
also adds some initial support for using kind to create types of a
specific kind.
This commit only allows the creation of the type 'character(kind=1)',
however, it will be easy enough to extend this in future to support
more type kinds.
The kind of any expression can be queried using the kind intrinsic
function. At the moment the kind returned corresponds to the size of
the type, this matches how gfortran handles kinds. However, the
correspondence between kind and type size depends on the compiler
and/or the specific target, so this might not be correct for
everyone. If we want to support different compilers/targets in future
the code to compute the kind from a type will need to be updated.

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.

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.

-fsanitize=undefined pointed out this error:
runtime error: load of value 2887952, which is not a valid value for type 'exp_opcode'
This happens in gdb.ada/complete.exp when processing "complete p
my_glob". This does not parse, so the Ada parser throws an exception;
but then the code in parse_exp_in_context_1 accepts the expression
anyway. However, as no elements have been written to the expression,
undefined behavior results.
The fix is to notice this case in parse_exp_in_context_1. This patch
also adds an assertion to prefixify_expression to enforce this
pre-existing constraint.

This change/patch substitues BLOCK_ENTRY_PC for BLOCK_START in
places where BLOCK_START is used to obtain the address at which
execution should enter the block. Since blocks can now contain
non-contiguous ranges, the BLOCK_START - which is still be the
very lowest address in the block - might not be the same as
BLOCK_ENTRY_PC.
There is a change to infrun.c which is less obvious and less mechanical.
I'm posting it as a separate patch.

While working on the parser code, I noticed that yyerror is exported
from each parser. It is used by this code in parse.c:
TRY
{
if (lang->la_parser (&ps))
lang->la_error (NULL);
}
However, it seems to me that la_error will never be called here,
because in every case, la_parser throws an exception on error -- each
implementation of yyerror just calls error.
So, this patch removes la_error and makes all the yyerror functions
static. This is handy primarily because it makes it simpler to make
the expression parsers pure.
Tested by the buildbot.

This is version 2 of the patch to add inclusive range support for
Rust. I believe it addresses all review comments.
Rust recently stabilized the inclusive range feature:
https://github.com/rust-lang/rust/issues/28237
An inclusive range is an expression like "..= EXPR" or "EXPR ..=
EXPR". It is like an ordinary range, except the upper bound is
inclusive, not exclusive.
This patch adds support for this feature to gdb.
Regression tested on x86-64 Fedora 27.

Running the new tests added later in the series on PPC64 (ELFv1)
revealed that the current ifunc support needs a bit of a design rework
to work properly on PPC64/ELFv1, as most of the new tests fail. The
ifunc support only kind of works today if the ifunc symbol and the
resolver have the same name, as is currently tested by the
gdb.base/gnu-ifunc.exp testcase, which is unlike how ifuncs are
written nowadays.
The crux of the problem is that ifunc symbols are really function
descriptors, not text symbols:
44: 0000000000020060 104 FUNC GLOBAL DEFAULT 18 gnu_ifunc_resolver
54: 0000000000020060 104 GNU_IFUNC GLOBAL DEFAULT 18 gnu_ifunc
But, currently GDB only knows about ifunc symbols that are text
symbols. GDB's support happens to work in practice for PPC64 when the
ifunc and resolver are one and only, like in the current
gdb.base/gnu-ifunc.exp testcase:
15: 0000000000020060 104 GNU_IFUNC GLOBAL DEFAULT 18 gnu_ifunc
because in that case, the synthetic ".gnu_ifunc" entry point text
symbol that bfd creates from the actual GNU ifunc "gnu_ifunc" function
(descriptor) symbol ends up with the the "is a gnu ifunc" flag set /
copied over:
(gdb) maint print msymbols
...
[ 8] i 0x9c4 .gnu_ifunc section .text <<< mst_text_gnu_ifunc
...
[29] D 0x20060 gnu_ifunc section .opd crtstuff.c <<< mst_data
But, if the resolver gets a distinct symbol/name from the ifunc
symbol, then we end up with this:
(gdb) maint print msymbols
[ 8] T 0x9e4 .gnu_ifunc_resolver section .text <<< mst_text
...
[29] D 0x20060 gnu_ifunc section .opd crtstuff.c <<< mst_data
[30] D 0x20060 gnu_ifunc_resolver section .opd crtstuff.c <<< mst_data
I have a follow up bfd patch that turns that into:
(gdb) maint print msymbols
+ [ 8] i 0x9e4 .gnu_ifunc section .text <<< mst_text_gnu_ifunc
[ 8] T 0x9e4 .gnu_ifunc_resolver section .text <<< mst_text
...
[29] D 0x20060 gnu_ifunc section .opd crtstuff.c
[30] D 0x20060 gnu_ifunc_resolver section .opd crtstuff.c
but that won't help everything. We still need this patch.
Specifically, when we do a symbol lookup by name, like e.g., to call a
function (see c-exp.y hunk), e.g., "p gnu_ifunc()", then we need to
know that the found "gnu_ifunc" minimal symbol is an ifunc in order to
do some special processing. But, on PPC, that lookup by name finds
the function descriptor symbol, which presently is just a mst_data
symbol, while at present, we look for mst_text_gnu_ifunc symbols to
decide whether to do special GNU ifunc processing. In most of those
places, we could try to resolve the function descriptor with
gdbarch_convert_from_func_ptr_addr, and then lookup the minimal symbol
at the resolved PC, see if that finds a minimal symbol of type
mst_text_gnu_ifunc. If so, then we could assume that the original
mst_dadta / function descriptor "gnu_ifunc" symbol was an ifunc. I
tried it, and it mostly works, even if it's not the most efficient.
However, there's one case that can't work with such a design -- it's
that of the user calling the ifunc resolver directly to debug it, like
"p gnu_ifunc_resolver(0)", expecting that to return the function
pointer of the final function (which is exercised by the new tests
added later). In this case, with the not-fully-working solution, we'd
resolve the function descriptor, find that there's an
mst_text_gnu_ifunc symbol for the resolved address, and proceed
calling the function as if we tried to call "gnu_ifunc", the
user-visible GNU ifunc symbol, instead of the resolver. I.e., it'd be
impossible to call the resolver directly as a normal function.
Introducing mst_data_gnu_ifunc eliminates the need for several
gdbarch_convert_from_func_ptr_addr calls, and, fixes the "call
resolver directly" use case mentioned above too. It's the cleanest
approach I could think of.
In sum, we make GNU ifunc function descriptor symbols get a new
"mst_data_gnu_ifunc" minimal symbol type instead of the bare mst_data
type. So when symbol lookup by name finds such a minimal symbol, we
know we found an ifunc symbol, without resolving the entry/text
symbol. If the user calls the the resolver symbol instead, like "p
gnu_ifunc_resolver(0)", then we'll find the regular mst_data symbol
for "gnu_ifunc_resolver", and we'll call the resolver function as just
another regular function.
With this, most of the GNU ifunc tests added by a later patch pass on
PPC64 too. The following bfd patch fixes the remaining issues.

This patch fixes a problem with using the MI -var-update command
to access the values of registers in frames other than the current
frame. The patch includes a test that demonstrates the problem:
* run so there are several frames on the stack
* create a fixed varobj for $pc in each frame, #'s 1 and above
* step one instruction, to modify the value of $pc
* call -var-update for each of the previously created varobjs
to verify that they are not reported as having changed.
Without the patch, the -var-update command reported that $pc for all
frames 1 and above had changed to the value of $pc in frame 0.
A varobj is created as either fixed, the expression is evaluated within
the context of a specific frame, or floating, the expression is
evaluated within the current frame, whatever that may be.
When a varobj is created by -var-create we set two fields of the varobj
to track the context in which the varobj was created, these two fields
are varobj->root->frame and var->root->valid_block.
If a varobj is of type fixed, then, when we subsequently try to
reevaluate the expression associated with the varobj we must determine
if the original frame (and block) is still available, if it is not then
the varobj can no longer be evaluated.
The problem is that for register expressions varobj->root->valid_block
is not set correctly. This block tracking is done using the global
'innermost_block' which is set in the various parser files (for example
c-exp.y). However, this is not set for register expressions.
The fix then seems like it should be to just update the innermost block
when parsing register expressions, however, that solution causes several
test regressions.
The problem is that in some cases we rely on the expression parsing
code not updating the innermost block for registers, one example is
when we parse the expression for a 'display' command. The display
commands treats registers like floating varobjs, but symbols are
treated like fixed varobjs. So 'display $reg_name' will always show
the value of '$reg_name' even as the user moves from frame to frame,
while 'display my_variable' will only show 'my_variable' while it is
in the current frame and/or block, when the user moves to a new frame
and/or block (even one with a different 'my_variable' in) then the
display of 'my_variable' stops. For the case of 'display', without
the option to force fixed or floating expressions, the current
behaviour is probably the best choice. For the varobj system though,
we can choose between floating and fixed, and we should try to make
this work for registers.
There's only one existing test case that needs to be updated, in that
test a fixed varobj is created using a register, the MI output now
include the thread-id in which the varobj should be evaluated, which I
believe is correct behaviour. I also added a new floating test case
into the same test script, however, right now this also includes the
thread-id in the expected output, which I believe is an existing gdb
bug, which I plan to fix next.
Tested on x86_64 Linux native and native-gdbserver, no regressions.

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).

When parsing floating-point literals, the language parsers currently
use parse_float or some equivalent routine to parse the input string
into a DOUBLEST, which is then stored within a OP_DOUBLE expression
node. When evaluating the expression, the OP_DOUBLE is finally
converted into a value in target format.
On the other hand, *decimal* floating-point literals are parsed
directly into target format and stored that way in a OP_DECFLOAT
expression node. In order to eliminate the DOUBLEST, this patch
therefore unifies the handling of binary and decimal floating-
point literals and stores them both in target format within a
new OP_FLOAT expression node, replacing both OP_DOUBLE and
OP_DECFLOAT.
In order to store literals in target format, the parse_float
routine needs to know the type of the literal. All parsers
therefore need to be changed to determine the appropriate type
(e.g. by detecting suffixes) *before* calling parse_float,
instead of after it as today. However, this change is mostly
straightforward -- again, this is already done for decimal FP
today.
The core of the literal parsing is moved into a new routine
floatformat_from_string, mirroring floatformat_to_string.
The parse_float routine now calls either floatformat_from_string
or decimal_from_sting, allowing it to handle any type of FP
literal.
All language parsers need to be updated. Some notes on
specific changes to the various languages:
- C: Decimal FP is now handled in parse_float, and no longer
needs to be handled specially.
- D: Straightforward.
- Fortran: Still used a hard-coded "atof", also replaced by
parse_float now. Continues to always use builtin_real_s8
as the type of literal, even though this is probably wrong.
- Go: This used to handle "f" and "l" suffixes, even though
the Go language actually doesn't support those. I kept this
support for now -- maybe revisit later. Note the the GDB
test suite for some reason actually *verifies* that GDB supports
those unsupported suffixes ...
- Pascal: Likewise -- this handles suffixes that are not
supported in the language standard.
- Modula-2: Like Fortran, used to use "atof".
- Rust: Mostly straightforward, except for a unit-testing hitch.
The code use to set a special "unit_testing" flag which would
cause "rust_type" to always return NULL. This makes it not
possible to encode a literal into target format (which type?).
The reason for this flag appears to have been that during
unit testing, there is no "rust_parser" context set up, which
means no "gdbarch" is available to use its types. To fix this,
I removed the unit_testing flag, and instead simply just set up
a dummy rust_parser context during unit testing.
- Ada: This used to check sizeof (DOUBLEST) to determine which
type to use for floating-point literal. This seems questionable
to begin with (since DOUBLEST is quite unrelated to target formats),
and in any case we need to get rid of DOUBLEST. I'm now simply
always using the largest type (builtin_long_double).

This simplifies the handling of funcall_chain, by changing it to be a
std::vector<int> and then fixing the users. This allows the removal
of a cleanup.
It would be even cleaner to replace this with better logic in the
parsers; but a baby step seemed ok.

Since 2273f0ac95a7 ("change minsyms not to be relocated at
read-time"), printing TLS symbols of objfiles with a non-zero base
address, without debug info, fails.
E.g., with:
$ mv /usr/lib/debug /usr/lib/debug-x
to get debug info out of the way, we get:
$ echo 'int main(){}' | gcc -pthread -x c -
$ ./gdb -q -ex start -ex 'p (int) errno' ./a.out
Cannot access memory at address 0xffffef7c0698
instead of the expected:
$1 = 0
The regression is not visible with glibc debuginfo installed.
The problem is that we compute the address of TLS minsyms incorrectly.
To trigger the problem, it is important that the variable is in an
objfile with a non-zero base address. While glibc is a shared library
for 'errno', it's easier for the testcase to use PIE instead of a
shlib. For TLS variables in PT_EXEC the regression obviously does not
happen.

Trying to print a function local static variable of a const-qualified
method still doesn't work after the previous fixes:
(gdb) p 'S::method() const'::static_var
$1 = {i1 = 1, i2 = 2, i3 = 3}
(gdb) p S::method() const::static_var
No symbol "static_var" in specified context.
The reason is that the expression parser/evaluator loses the "const",
and the above unquoted case is just like trying to print a variable of
the non-const overload, if it exists, even. As if the above unquoted
case had been written as:
(gdb) p S::method()::static_var
No symbol "static_var" in specified context.
We can see the problem without static vars in the picture. With:
struct S
{
void method ();
void method () const;
};
Compare:
(gdb) print 'S::method(void) const'
$1 = {void (const S * const)} 0x400606 <S::method() const>
(gdb) print S::method(void) const
$2 = {void (S * const)} 0x4005d8 <S::method()> # wrong method!
That's what we need to fix. If we fix that, the function local static
case starts working.
The grammar production for function/method types is this one:
exp: exp '(' parameter_typelist ')' const_or_volatile
This results in a TYPE_INSTANCE expression evaluator operator. For
the example above, we get something like this ("set debug expression 1"):
...
0 TYPE_INSTANCE 1 TypeInstance: Type @0x560fda958be0 (void)
5 OP_SCOPE Type @0x560fdaa544d8 (S) Field name: `method'
...
While evaluating TYPE_INSTANCE, we end up in
value_struct_elt_for_reference, trying to find the method named
"method" that has the prototype recorded in TYPE_INSTANCE. In this
case, TYPE_INSTANCE says that we're looking for a method that has
"(void)" as parameters (that's what "1 TypeInstance: Type
@0x560fda958be0 (void)" above means. The trouble is that nowhere in
this mechanism do we communicate to value_struct_elt_for_reference
that we're looking for the _const_ overload.
value_struct_elt_for_reference only compared parameters, and the
non-const "method()" overload has matching parameters, so it's
considered the right match...
Conveniently, the "const_or_volatile" production in the grammar
already records "const" and "volatile" info in the type stack. The
type stack is not used in this code path, but we can borrow the
information. The patch converts the info in the type stack to an
"instance flags" enum, and adds that as another element in
TYPE_INSTANCE operators. This type instance flags is then applied to
the temporary type that is passed to value_struct_elt_for_reference
for matching.
The other side of the problem is that methods in the debug info aren't
marked const/volatile, so with that in place, the matching never finds
const/volatile-qualified methods.
The problem is that in the DWARF, there's no indication at all whether
a method is const/volatile qualified... For example (c++filt applied
to the linkage name for convenience):
<2><d3>: Abbrev Number: 6 (DW_TAG_subprogram)
<d4> DW_AT_external : 1
<d4> DW_AT_name : (indirect string, offset: 0x3df): method
<d8> DW_AT_decl_file : 1
<d9> DW_AT_decl_line : 58
<da> DW_AT_linkage_name: (indirect string, offset: 0x5b2): S::method() const
<de> DW_AT_declaration : 1
<de> DW_AT_object_pointer: <0xe6>
<e2> DW_AT_sibling : <0xec>
I see the same with both GCC and Clang. The patch works around this
by extracting the cv qualification from the "const" and "volatile" in
the demangled name. This will need further tweaking for "&" and
"const &" overloads, but we don't support them in the parser yet,
anyway.
The TYPE_CONST changes were necessary otherwise the comparisons in valops.c:
if (TYPE_CONST (intype) != TYPE_FN_FIELD_CONST (f, j))
continue;
would fail, because when both TYPE_CONST() TYPE_FN_FIELD_CONST() were
true, their values were different.
BTW, I'm recording the const/volatile-ness of methods in the
TYPE_FN_FIELD info because #1 - I'm not sure it's kosher to change the
method's type directly (vs having to call make_cv_type to create a new
type), and #2 it's what stabsread.c does:
...
case 'A': /* Normal functions. */
new_sublist->fn_field.is_const = 0;
new_sublist->fn_field.is_volatile = 0;
(*pp)++;
break;
case 'B': /* `const' member functions. */
new_sublist->fn_field.is_const = 1;
new_sublist->fn_field.is_volatile = 0;
...
After all this, this finally all works:
print S::method(void) const
$1 = {void (const S * const)} 0x400606 <S::method() const>
(gdb) p S::method() const::static_var
$2 = {i1 = 1, i2 = 2, i3 = 3}

This commit makes "print S::method()::static_var" actually find the
debug symbol for static_var. Currently, you get:
(gdb) print S::method()::static_var
A syntax error in expression, near `'.
Quoting the whole string would seemingly work before the previous
patch that made GDB stop assuming int for no-debug-info variables:
(gdb) p 'S::method()::static_var'
$1 = 1
... except that's incorrect output, because:
(gdb) ptype 'S::method()::static_var'
type = <data variable, no debug info>
The way to make it work correctly currently is by quoting the
function/method part, like this:
(gdb) print 'S::method()'::static_var
$1 = {i1 = 1, i2 = 2, i3 = 3}
(gdb) ptype 'S::method()'::static_var
type = struct aggregate {
int i1;
int i2;
int i3;
}
At least after the "stop assuming int" patch, this is what we
now get:
(gdb) p 'S::method()::static_var'
'S::method()::static_var' has unknown type; cast it to its declared type
(gdb) p (struct aggregate) 'S::method()::static_var'
$1 = {i1 = 1, i2 = 2, i3 = 3}
However, IMO, users shouldn't really have to care about any of this.
GDB should Just Work, without quoting, IMO.
So here's a patch that implements support for that in the C++ parser.
With this patch, you now get:
(gdb) p S::method()::S_M_s_var_aggregate
$1 = {i1 = 1, i2 = 2, i3 = 3}
(gdb) ptype S::method()::S_M_s_var_aggregate
type = struct aggregate {
int i1;
int i2;
int i3;
}

The previous patch left GDB with an inconsistency. While with normal
expression evaluation the "unknown return type" error shows the name
of the function that misses debug info:
(gdb) p getenv ("PATH")
'getenv' has unknown return type; cast the call to its declared return type
^^^^^^
which can by handy in more complicated expressions, "ptype" does not:
(gdb) ptype getenv ("PATH")
function has unknown return type; cast the call to its declared return type
^^^^^^^^
This commit is a step toward fixing it.
The problem is that while evaluating the expression above, we have no
reference to the minimal symbol where we could extract the name from.
This is because the resulting expression tree has no reference to the
minsym at all. During parsing, the type and address of the minsym are
extracted and an UNOP_MEMVAL / UNOP_MEMVAL_TLS operator is generated
(see write_exp_elt_msym). With "set debug expression", here's what
you see:
0 OP_FUNCALL Number of args: 0
3 UNOP_MEMVAL Type @0x565334a51930 (<text variable, no debug info>)
6 OP_LONG Type @0x565334a51c60 (__CORE_ADDR), value 140737345035648 (0x7ffff7751d80)
The "print" case finds the function name, because
call_function_by_hand looks up the function by address again.
However, for "ptype", we don't reach that code, because obviously we
don't really call the function.
Unlike minsym references, references to variables with debug info have
a pointer to the variable's symbol in the expression tree, with
OP_VAR_VALUE:
(gdb) ptype main()
...
0 OP_FUNCALL Number of args: 0
3 OP_VAR_VALUE Block @0x0, symbol @0x559bbbd9b358 (main(int, char**))
...
so I don't see why do minsyms need to be different. So to prepare for
fixing the missing function name issue, this commit adds a new
OP_VAR_MSYM_VALUE operator that mimics OP_VAR_VALUE, except that it's
for minsyms instead of debug symbols. For infcalls, we now get
expressions like these:
0 OP_FUNCALL Number of args: 0
3 OP_VAR_MSYM_VALUE Objfile @0x1e41bf0, msymbol @0x7fffe599b000 (getenv)
In the following patch, we'll make OP_FUNCALL extract the function
name from the symbol stored in OP_VAR_VALUE/OP_VAR_MSYM_VALUE.
OP_VAR_MSYM_VALUE will be used more in a later patch in the series
too.
