This makes sure that the types of the arguments are taken into account
when performing an inferior function call to a non-C (or C-like)
function. In particular, this makes sure that the arguments are
appropriatly converted to the correct type.
For instance, on x86_64-linux, with the following Ada code:
procedure Set_Float (F : Float) is
begin
Global_Float := F;
end Set_Float;
The following sequence shows that Float arguments are incorrectly
passed (Ada's Float type is the equivalent of type "float" in C):
(gdb) call set_float (2.0)
(gdb) print global_float
$1 = 0.0
Putting a breakpoint inside set_float to inspect the value of
register xmm0 gives the first hint of the problem:
(gdb) p $xmm0
$2 = (v4_float => (0 => 0.0, 2.0, 0.0, 0.0),
v2_double => (0 => 2.0, 0.0),
[...]
It shows that the argument was passed as a double.
The code responsible for doing appropriate type conversions
for the arguments (value_arg_coerce) found that our function
was not prototyped, and thus could not use typing information
for the arguments. Instead, it defaulted to the value of "set
coerce-float-to-double", which by default is true, to determine
the argument type.
This patch fixes the problem by setting the PROTOTYPE flag
for all functions of any language except C and Objective C.
gdb/ChangeLog:
* dwarf2read.c (prototyped_function_p): New function.
(read_subroutine_type): Use it.
gdb/testsuite/ChangeLog:
* gdb.ada/float_param: New testcase.
This patch de-indents the code provided as a comment explaining
how the code declaring the ld_info32_desc and ld_info64_desc globals
was generated. The intent is to avoid an ARI warning about a macro
not starting at column zero of the line.

as a comment.

This results in an internal-warning when trying the completion
when in Ada mode:
(gdb) b simple<TAB>
/[...]/cleanups.c:265: internal-warning: restore_my_cleanups has found a stale cleanup
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
gdb/ChangeLog:
* ada-lang.c (ada_make_symbol_completion_list): Make sure
all cleanups are done before returning from this function.
gdb/testsuite/ChangeLog:
* gdb.ada/complete.exp: Add test verifying completion using
the "tab" key.
These forward declarations are a GNU extension, and they trigger
a build warning when the compiler does not support it.
gdb/ChangeLog:
* utils.h: #include "exceptions.h".
(enum errors): Remove partial declaration.
The current code attempts to provide relocation support when debugging
core files via the rs6000_xfer_partial method of the rs6000-nat
target_ops vector. However, this target_ops vector does not get pushed
on the target stack at all when debugging core files, thus bypassing
completely that part of the code.
This patch fixes the problem by extending corelow's core_xfer_partial
into handling the TARGET_OBJECT_LIBRARIES_AIX object.
gdb/ChangeLog:
* gdbarch.sh (core_xfer_shared_libraries_aix): New method.
* gdbarch.h, gdbarch.c: Regenerate.
* corelow.c (core_xfer_partial): Add TARGET_OBJECT_LIBRARIES_AIX
handling.
