Currently, GDB is not able to set a breakpoint at subprogram post
prologue for flang generated binaries. This is due to clang having
two line notes one before and another after the prologue.
Now the end of prologue is determined using symbol table, which was
the way for clang generated binaries already. Since clang and flang
both share same back-end it is true for flang as well.

* amd64-tdep.c (amd64_skip_prologue): Using symbol table
to find the end of prologue for flang compiled binaries.

The debug prints inside linux-nat.c almost all have a prefix that
indicate in which function they are located. This prefix is an
abbreviation of the function name. For example, this print is in the
`linux_nat_post_attach_wait` function:
if (debug_linux_nat)
fprintf_unfiltered (gdb_stdlog,
"LNPAW: Attaching to a stopped process\n");
Over time, the code has changed, things were moved, and many of these
prefixes are not accurate anymore. Also, unless you know the
linux-nat.c file by heart, it's a bit cryptic what LLR, LNW, RSRL, etc,
all mean.
To address both of these issues, I suggest adding this macro for
printing debug statements, which automatically includes the function
name. It also includes the `[linux-nat]` prefix to clarify which part
of GDB printed this (I think that, ideally, all debug prints would
include such a tag).
The `__func__` magic symbol is used to get the function name.
Unfortunately, in the case of methods, it only contains the method name,
not the class name. So we'll get "wait", where I would have liked to
get "linux_nat_target::wait". But at least with the `[linux-nat]` tag
in the front, it's not really ambiguous.
I've made the macro automatically include the trailing newline, because
it wouldn't make sense to call it twice to print two parts of one line,
the `[linux-nat]` tag would be printed in the middle.
An advantage of this (IMO) is that it's less verbose, we don't have to
check for `if (debug_linux_nat)` everywhere.
Another advantage is that it's easier to customize the output later,
without having to touch all call sites.
Here's an example of what it looks like in the end:
[linux-nat] linux_nat_wait_1: enter
[linux-nat] wait: [process -1], [TARGET_WNOHANG]

In PR rust/26197, Tom de Vries notes that the variant part rewrite
caused some regressions for the Rust compiler he has. This compiler
is unusual in that it combines a relatively recent rustc with a
relatively old LLVM -- so variant parts are not emitted using DWARF.
Most of the bugs in that PR were already fixed by earlier patches, but
some lingered. After some research we found that some of these never
did work -- which is consistent with the investigations we did into
the debug info -- but instead were xfail'd. This patch updates the
xfails to cope with the new output. (After this, just one failure
remains.)
Tom de Vries tested this using his rustc and suggested a fix that
appears in this version.

I happened to notice that using -var-create at a certain spot in an
Ada program caused a crash. This happens because
ada_get_decoded_value can return NULL -- in particular, deeper in the
code it can hit this return in ada_type_of_array:
descriptor = desc_bounds (arr);
if (value_as_long (descriptor) == 0)
return NULL;
This patch avoids the crash by handling this NULL return.

An internal test failed on a riscv64-elf cross build because
Inferior.search_memory returned a negative value. I tracked this down
to to use of PyLong_FromLong in infpy_search_memory. Then, I looked
at other conversions of CORE_ADDR to Python and fixed these as well.
I don't think there is a good way to write a test for this.

This patch fixes an internal error in GAS when defining a section using
a symbol that has already been named but not defined. For a minimal
reproducer, try the following input:
a=b
.sect a
The problem is that obj_elf_change_section() happily reuses the symbol
"a" created by equals() without clearing the sy_value field: prior to
this patch, it just set bsym. This caused a problem when attempting to
resolve the section symbol, since resolve_symbol_value() ended up
resolving the symbol as if it were the original symbol created by
equals(), which ends up leaving the section symbol in the undefined
section instead of in section a, hence the call to abort() in
S_SET_SEGMENT().

when trying to print the high bound of a TYPE_CODE_RANGE, which has m_kind
PROP_LOCEXPR, while the code in resolve_dynamic_type assumes PROP_CONST.
Fix this by extending the printing of TYPE_CODE_RANGE to allow

In gdb.fortran/mixed-lang-stack.f90, we have fortran function mixed_func_1d:
...
subroutine mixed_func_1d(a, b, c, d, str)
use, intrinsic :: iso_c_binding, only: c_int, c_float, c_double
use, intrinsic :: iso_c_binding, only: c_float_complex
implicit none
integer(c_int) :: a
real(c_float) :: b
real(c_double) :: c
complex(c_float_complex) :: d
character(len=*) :: str
...
which we declare in C in gdb.fortran/mixed-lang-stack.c like this:
...
extern void mixed_func_1d_ (int *, float *, double *, complex float *,
char *, size_t);
...
The fortran string parameter str is passed as a char *, and an additional
argument str_ for the string length. The type used for the string length
argument is size_t, but for gcc 7 and earlier, the actual type is int
instead ( see
https://gcc.gnu.org/onlinedocs/gfortran/Argument-passing-conventions.html ).
Fix this by declaring the string length type depending on the gcc version:
...
#if !defined (__GNUC__) || __GNUC__ > 7
typedef size_t fortran_charlen_t;
#else
typedef int fortran_charlen_t;
...
Tested on x86_64-linux, with gcc-7 and gcc-8.

When running test-case gdb.fortran/mixed-lang-stack.exp, it passes, but we
find in gdb.log:
...
(gdb) bt^M
...
#7 0x000000000040113c in mixed_func_1b (a=1, b=2, c=3, d=(4,5), \
e=<error reading variable: value requires 140737488341744 bytes, which \
is more than max-value-size>, g=..., _e=6) at mixed-lang-stack.f90:87^M
...
while a bit later in gdb.log, we have instead for the same frame (after
adding a gdb_test_no_output "set print frame-arguments all" to prevent
getting "e=..."):
...
(gdb) up^M
#7 0x000000000040113c in mixed_func_1b (a=1, b=2, c=3, d=(4,5), \
e='abcdef', g=( a = 1.5, b = 2.5 ), _e=6) at mixed-lang-stack.f90:87^M
...
The difference is that in the latter case, we print the frame while it's
selected, while in the former, it's not.
The problem is that while trying to resolve the dynamic type of e in
resolve_dynamic_type, we call dwarf2_evaluate_property with a frame == NULL
argument, and then use the selected frame as the context in which to evaluate
the dwarf property, effectively evaluating a DW_OP_fbreg operation in the
wrong frame context.
Fix this by temporarily selecting the frame of which we're trying to print the
arguments in print_frame_args, borrowing code from print_frame_local_vars that
was added to fix a similar issue in commit 16c3b12f19 "error/internal-error
printing local variable during "bt full".
Build and tested on x86_64-linux.

git commit 49d9fd42acef chose to make nm print 'C' for the normal
common section, and 'c' for other commons. This was an attempt to
make common symbols in .scommon and other small common sections show
a 'c' type without a section name comparison, but it failed for
nm --plugin on lto objects where normal common symbols are stashed in
a "plug" section. It's also wrong for large common symbols. So
instead set SEC_SMALL_DATA on sections created for small commons, and
key off that flag to show 'c' type. If your ELF target doesn't have
an elf_backend_symbol_processing function, then you won't see 'c' for
symbols in .scommon.
Note that due to bfd_decode_symclass decoding common symbols without
a chance for coff_section_type to treat .scommon specially, then
having .scommon in the array of special sections handled by
coff_section_type prior to 49d9fd42acef was entirely ineffective.
That fact escaped me when writing 49d9fd42acef. Unless .scommon
didn't have SEC_IS_COMMON set, which would be a little weird.

This patches changes low_prepare_to_resume in the ppc linux native target
to always clear the watchpoint when the old PTRACE_SET_DEBUGREG interface
is used, even if another watchpoint GDB requested to the target is
written right after using the same call.
The reason for this is that there were some older kernel versions for
which overwriting a watchpoint with PTRACE_SET_DEBUGREG would not
re-activate the watchpoint if it was previouly disabled following a hit.
This happened when the kernel was configured with CONFIG_HW_BREAKPOINT on
and uses perf events to install watchpoints.
Previously, the ppc linux native target would immediately remove or
insert watchpoints following a request from the upper layers. This was
changed in commit 227c0bf4b3dd0cf65dceb58e729e9da81b38b5a7 to fix other
issues, which caused watchpoint requests to be applied to the inferior
only in low_prepare_to_resume, right before the inferior is resumed.
Usually, but maybe not always, after a hit, GDB will remove the
watchpoint, resume the inferior for a single-step, possibly report the
watchpoint hit to the user, and then re-insert the watchpoint before the
inferior is next resumed. In this case there would be no problems, but
since I can't guarantee that there aren't other paths in GDB that allow
the user to set a new watchpoint after the first one hit, and after its
deletion by GDB, but before the inferior is resumed, there is a chance
that PTRACE_SET_DEBUGREG could be called directly without the watchpoint
first having been cleared, which could cause a false negative with the
older kernel versions.
This issue would affect kernel versions starting from this commit:
