Consider a function with the following signature...
function F (R : out Rec_Type) return Enum_Type;
... where Rec_Type is a simple record:
type Rec_Type is record
Cur : Integer;
end record;
Trying to "finish" from that function causes GDB to SEGV:
(gdb) fin
Run till exit from #0 bar.f (r=...) at bar.adb:5
0x00000000004022fe in foo () at foo.adb:5
5 I : Enum_Type := F (R);
[1] 18949 segmentation fault (core dumped) /[..]/gdb
This is related to the fact that funtion F has a parameter (R)
which is an "out" parameter being passed by copy. For those,
GNAT transforms the return value to be a record with multiple
fields: The first one is called "RETVAL" and contains the return
value shown in the source, and the remaining fields have the same
name as the "out" or "in out" parameters which are passed by copy.
So, in the example above, function F returns a struct that has
one field who name is "r".
Because "RETVAL" starts with "R", GDB thinks it's a wrapper field,
because it looks like the encoding used for variant records:
-- member_name ::= {choice} | others_choice
-- choice ::= simple_choice | range_choice
-- simple_choice ::= S number
-- range_choice ::= R number T number <<<<<----- here
-- number ::= {decimal_digit} [m]
-- others_choice ::= O (upper case letter O)
See ada_is_wrapper_field:
return (name != NULL
&& (startswith (name, "PARENT")
|| strcmp (name, "REP") == 0
|| startswith (name, "_parent")
|| name[0] == 'S' || name[0] == 'R' || name[0] == 'O'));
As a result of this, when trying to print the RETURN value,
we think that RETVAL is a wrapper, and thus recurse into
print_field_values...
if (ada_is_wrapper_field (type, i))
{
comma_needed =
print_field_values (TYPE_FIELD_TYPE (type, i),
valaddr,
(offset
+ TYPE_FIELD_BITPOS (type, i) / HOST_CHAR_BIT),
stream, recurse, val, options,
comma_needed, type, offset, language);
... which is a problem since print_field_values assumes that
the type it is given ("TYPE_FIELD_TYPE (type, i)" here), is also
a record type. However, that's not the case, since RETVAL is
an enum. That eventually leads GDB to a NULL type when trying to
extract fields out of the enum, which then leads to a SEGV when
trying to dereference it.
Ideally, we'd want to be a little more careful in identifying
wrapper fields, by enhancing ada_is_wrapper_field to be a little
more complete in its analysis of the field name before declaring
it a variant record wrapper. However, it's not super easy to do
so, considering that the choices can be combined together when
complex choices are used. Eg:
-- [...] the choice 1 .. 4 | 7 | -10 would be represented by
-- R1T4S7S10m
Given that we are working towards getting rid of GNAT encodings,
which means that the above will eventually disappear, we took
the more pragmatic approach is just treating RETVAL as a special
case.

Some of the source code for the test cases in the GDB testsuite
reside in .S files containing assembly code. These files typically
define a symbol - such as main - which may, depending on the target,
require a prefix such as underscore.
For example, gdb.dwarf2/dw-compdir-oldgcc.S defines the symbol main:
main: .globl main
Some targets, such as rx-elf, require main to have an underscore
prefix. (If it doesn't, a linker error results due to not being able
to find _main required by crt0.o.) So, instead, the above should look
like this for rx-elf and other targets with this same requirement:
_main: .globl _main
This patch defines a new tcl proc in lib/gdb named
gdb_target_symbol_prefix_flags_asm. This proc returns a string
which will - assuming everything else is wired up correctly - cause
-DSYMBOL_PREFIX=_ to be passed on the command line to the compiler.
The test cases are augmented with a macro definition for SYMBOL
as follows:
#define CONCAT1(a, b) CONCAT2(a, b)
#define CONCAT2(a, b) a ## b
#ifdef SYMBOL_PREFIX
# define SYMBOL(str) CONCAT1(SYMBOL_PREFIX, str)
#else
# define SYMBOL(str) str
#endif
Symbols, such as main shown in the example earlier are then wrapped
with SYMBOL like this:
SYMBOL(main): .globl SYMBOL(main)
The net effect will be to add a prefix for those targets which need
it and add no prefix for those targets which do not.
It should be noted that there was already a proc in lib/gdb.exp
called gdb_target_symbol_prefix_flags. It still exists, but has
been significantly rewritten. (There is only one small difference
between the two versions.)
That proc used to explicitly list targets which were known to
require an underscore prefix. This is no longer done; the recently
added proc, gdb_target_symbol_prefix, is now invoked to dynamically
discover whether or not a prefix is required for that particular
target.
The difference between gdb_target_symbol_prefix_flags_asm
and gdb_target_symbol_prefix_flags is that the former returns
a bare prefix while the latter returns the prefix enclosed in
double quotes. I.e. assuming that the discovered prefix is
underscore, gdb_target_symbol_prefix_flags_asm returns:
additional_flags=-DSYMBOL_PREFIX=_
while gdb_target_symbol_prefix_flags returns:
additional_flags=-DSYMBOL_PREFIX="_"
The double-quoted version is not suitable for using with .S files
containing assembly code; there is no way to strip the double quotes
using C preprocessor constructs.
It would be possible to use the bare (non double quoted) version in
C source code. However, the supporting macros become more complicated
and therefore more difficult to maintain.

Building libiberty on Android currently fails with the error message
shown below. This was discovered by trying to build GDBserver
for Android, which stopped building after libiberty became
a GDBserver dependency.
Here is the error message:
[...]/getpagesize.c:64:1: error: redefinition of 'getpagesize'
In file included from /[...]/getpagesize.c:34:0:
/[...]/usr/include/unistd.h:171:23: note: previous definition of 'getpagesize' was here
And looking at the definition, one can see that it defined as
a static inline function...
static __inline__ int getpagesize(void) {
extern unsigned int __page_size;
return __page_size;
}
... which explains why the AC_CHECK_FUNCS test failed to detect
the function, since there is no associated symbol to be linked in.
This patch prevents getpagesize.c to be compiled in by hard-coding
the fact that getpagesize is available on android hosts.
libiberty/ChangeLog:
* configure.ac: Set AC_CV_FUNC_GETPAGESIZE to "yes" on
Android hosts.
* configure: Regenerate.
Some of the tests in gdb.dwarf2 which use Dwarf::assemble refer to
(minimal/linker) symbols created in the course of building a small
test program. Some targets use a prefix such as underscore ("_") on
these symbols. Many of the tests in gdb.dwarf2 do not take this into
account. As a consequence, these tests fail to build, resulting
either in failures or untested testcases.
Here is an example from gdb.dwarf2/dw2-regno-invalid.exp:
Dwarf::assemble $asm_file {
cu {} {
compile_unit {
{low_pc main DW_FORM_addr}
{high_pc main+0x10000 DW_FORM_addr}
} {
...
}
For targets which require an underscore prefix on linker symbols,
the two occurrences of "main" would have to have a prepended underscore,
i.e. _main instead of main.
For the above case, a call to the new proc gdb_target_symbol is used
prepend the correct prefix to the symbol. I.e. the above code is
rewritten (as shown in the patch) as follows:
Dwarf::assemble $asm_file {
cu {} {
compile_unit {
{low_pc [gdb_target_symbol main] DW_FORM_addr}
{high_pc [gdb_target_symbol main]+0x10000 DW_FORM_addr}
} {
...
}
I also found it necessary to make an adjustment to lib/dwarf.exp so that
expressions of more than just one list element can be used in DW_TAG_...
constructs. Both atomic-type.exp and dw2-bad-mips-linkage-name.exp require
this new functionality.

Gold does not support all the emulations that Gnu ld does, and supports
only one spelling per target. The -m option is used only in the rare case
where there are no ELF input files, and we produce an empty output file.
In those cases, users are expected to supply a -m option naming one of
the supported emulations. In the many cases where a build script provides
an unnecessary -m option naming an emulation that gold does not support,
we will simply ignore the option, as we did before the reverted patch.

I think some older gfortran did initialize allocated memory but that is an
unspecified behavior. I haven't found any initialization mentioned
in Fortran 90 standard (draft) and it is also clearly stated here:
https://software.intel.com/en-us/forums/intel-fortran-compiler-for-linux-and-mac-os-x/topic/268786
Initialization to 0 of allocated arrays (of integers) is an
implementation issue. i.e. do not rely on it.

Add support for the /s modifier of the "record instruction-history" command. It
behaves exactly like /m and prints disassembled instructions in the order in
which they were recorded with interleaved sources. We accept /s in addition
to /m to align with the "disassemble" command.
The "record instruction-history" modifiers were not documented. Document
all of them.

* NEWS: Announce record instruction-history's new /s modifier.
doc/
* gdb.texinfo (Process Record and Replay): Document "record
instruction-history" modifiers.
The /m modifier interleaves source lines with the disassembly of recorded
instructions. This calls disasm.c's gdb_disassembly once for each recorded
instruction to be printed.
This doesn't really work because gdb_disassembly may choose not to print
anything in some situations. And if it does print something, the output
interferes with btrace_insn_history's output around it.
It further results in a separate asm_insns list for each instruction in MI.
Even though there is no MI support for target record, yet, we fix this obvious
issue.
Change record instruction-history /m to use the new gdb_pretty_print_insn
function for printing a single instruction and interleave source lines as
appropriate.
We cannot reuse the new disasm.c do_mixed_source_and_assembly function without
significant changes to it.

(btrace_insn_history): Add source interleaving algorithm.
The "record instruction-history" command prints for each instruction in
addition to the instruction's disassembly:
- the instruction number in the recorded execution trace
- a '?' before the instruction if it was executed speculatively
To allow the "record instruction-history" command to use GDB's disassembly
infrastructure, we extend gdb_pretty_print_insn to optionally print those
additional fields and export the function.
Add a new struct disasm_insn to add additional fields describing the
to-be-disassembled instruction. The additional fields are:
number an optional instruction number, zero if omitted.
is_speculative a predicate saying whether the instruction was
executed speculatively.
If non-zero, the instruction number is printed first. It will also appear
as a new optional field "insn-number" in MI. The field will be present if
insn_num is non-zero.
If is_speculative is set, speculative execution will be indicated by a "?"
following the new instruction number field. Unless the PC is omitted, it
will overwrite the first byte of the PC prefix. It will appear as a new
optional field "is-speculative" in MI. The field will contain "?" and will
be present if is_speculative is set.
The speculative execution indication is guarded by a new flag
DISASSEMBLY_SPECULATION.
Replace the PC parameter of gdb_pretty_print_insn with a pointer to the above
struct. GDB's "disassemble" command does not use the new fields.
