AArch64: Implement choice between Cortex-A53 erratum workarounds. (PR ld/24373)
The Cortex-A53 erratum currently has two ways it can resolve the erratum when
using the flag --fix-cortex-a53-843419:
1) If the address is within the range of an ADR instruction it rewrites the ADRP
into an ADR, and those doesn't need the use of a veneer.
2) If the address is not within range, it adds a branch to a veneer which will
execute the final bit of the erratum workaround and branch back to the call
site.
When we do this we always generate the veneers and we always align the size of
the text section to 4KB. This is because we only know which workaround we can
use after all linking has finished and all addresses are known. This means even
though the veneers are not used, we still generate the section and we still
change the size of the input section.
This is problematic for small memory devices as this would require the user to
take about a ~4KB hit in memory even though it's not even used.
Since there's no real way to restart the linking process from the final write
phase this patch solves the issue by allowing the user more control over which
erratum workaround gets used.
Concretely this changes the option --fix-cortex-a53-843419 to take optional
arguments --fix-cortex-a53-843419[=full|adr|adrp]
- full (default): Use both ADRP and ADR workaround. This is equivalent to not
specifying any options and is the default behavior before this
patch.
- adr: Only use the ADR workaround, this will not cause any increase in binary
size but linking will fail if the referenced address is out of range of
an ADR instruction.
- adrp: Use only the ADRP workaround, this will never rewrite your ADRP.
In the cases where the user knows how big their binaries are the `adr` option
would prevent the unneeded overhead.

Fix PR 24571 - Relaxation does not shorten jmp or call to target at pc-relative range boundary
The range check done to transform an absolute call/jump to a pc-relative one is
off-by-one, and that causes this shortening optimization to be missed if the
branch target is right at the range boundary.
In the non-shrinkable case, the range is what is mentioned in the ISA - -4094
bytes in the backward direction, and 4096 bytes in the positive direction.
In the shrinkable case, the forward jump range increases by two bytes (deleted
because of the shortening from call/jmp to rcall/rjmp), and therefore, the
range is -4094 in the reverse, and 4098 in the positive direction.
Fix the ranges for !shrinkable and shrinkable cases, and add a test caes to
ensure jumps to max forward and backward ranges get relaxed to rjmp.

Fix PR 24564 - link fails for some rcalls/rjmps with wraparound
The current code to compute relative distance in the wrap around case does not
handle the edge case of the target (after adjusting for implicit PC increment)
being exactly half of the wrap around distance. This patch fixes that and adds a
testcase.
The range for a forward relative jump call is 4096 bytes ((2 * 2047) + (2 bytes
for the implicit PC increment)). If the target of the jump is at a distance of
4098 bytes, it is out of range for a forward jump - however, a backward jump can
still reach that address if pmem-wrap-around is 8192.
Assume address 0 has rjmp to address 4098. With a wrap around of 8192 and
*without* adjusting for the implicit PC increment of 2 bytes, rjmp .-4096 will
jump to address 4096 (wrap around at 8192 and decreasing addresses from then
on). Adjusting 2 bytes for the implicit PC increment, the actual target is 4098.
avr_relative_distance_considering_wrap_around though, does the wrap around only
if the passed in distance is less than half of the wrap around distance. In this
case, it is exactly equal to half (original distance 4098, adjusted distance of
4096 and wraparound of 8192), and the bypassed wrap around causes the reloc
overflow error.
Fix by wrapping around even if adjusted distance is equal to half of wrap around
distance.

gdb/fortran: Use floatformats_ia64_quad for fortran 16-byte floats
PR gdb/18644 is caused by GDB using the wrong floating point format
for gfortran's 16-byte floating point type, including when the 16-byte
float is used as the component of a 32-byte complex type.
This commit addresses the issue in two places, first in i386-tdep.c,
there is already some code to force the use of floatformats_ia64_quad
for specific named types, this is extended to include the type names
that gfortran uses for its 16-byte floats.
Second, the builtin 16-byte float type (in f-lang.c) is changed so it
no longer uses gdbarch_long_double_format. On i386 this type is not
16-bytes, but is smaller, this is not what gfortran is expecting.
Instead we now use gdbarch_floatformat_for_type and ask for a
16-byte (128 bit) type using the common gfortran type name. This is
then spotted in i386-tdep.c (thanks to the first change above) and we
again get floatformats_ia64_quad returned.
This patch was tested on X86-64/GNU-Linux using '--target_board=unix'
and '--target_board=unix/-m32', and resolves all of the known failures
associated with PR gdb/18644. I've also added the test case from the

MI: Add new command -complete
There is a CLI command 'complete' intended to use with emacs. Such a command
would also be useful for MI frontends, when separate CLI and MI channels cannot
be used. For example, on Windows (because of lack of PTYs) or when GDB is used
through SSH session.
This commit adds a new '-complete' MI command.

This error happens as follows.
The function find_partial_die has a cu argument, but returns a pdi which may
or may not be from that cu:
...
/* Find a partial DIE at OFFSET, which may or may not be in CU,
except in the case of .debug_types DIEs which do not reference
outside their CU (they do however referencing other types via
DW_FORM_ref_sig8). */
static struct partial_die_info *
find_partial_die (sect_offset sect_off, int offset_in_dwz, struct dwarf2_cu *cu)
...
So the pdi returned by find_partial_die here in partial_die_parent_scope may
be from another cu:
...
partial_die_parent_scope (struct partial_die_info *pdi,
struct dwarf2_cu *cu)
{
const char *grandparent_scope;
struct partial_die_info *parent, *real_pdi;
/* We need to look at our parent DIE; if we have a DW_AT_specification,
then this means the parent of the specification DIE. */
real_pdi = pdi;
while (real_pdi->has_specification)
real_pdi = find_partial_die (real_pdi->spec_offset,
real_pdi->spec_is_dwz, cu);
parent = real_pdi->die_parent;
...
in which case both real_pdi and parent will be not from cu, but from another
one, say cu2.
Subsequently, cu's comp_unit_obstack is used to set parent->scope:
...
parent->scope = typename_concat (&cu->comp_unit_obstack,
grandparent_scope,
parent->name, 0, cu);
...
So, we use cu->comp_unit_obstack to assign a value to the scope field of
a pdi belonging to cu2, and when cu is deleted, the scope field points to a
freed value.
Fix this by making find_partial_die return the cu corresponding to the
returned pdi, and handling this at the call sites.
Tested on x86_64-linux.
