Yao Qi 187f5d00ac [AArch64] Track FP registers in prologue analyzer
We don't track FP registers in aarch64 prologue analyzer, so this causes
an internal error when FP registers are saved by "stp" instruction in
prologue (stp	d8, d9, [sp,#128]),

 tbreak _Unwind_RaiseException^M
 aarch64-tdep.c:335: internal-error: CORE_ADDR aarch64_analyze_prologue(gdbarch*, CORE_ADDR, CORE_ADDR, aarch64_prologue_cache*): Assertion `inst.operands[0].type == AARCH64_OPND_Rt' failed.^M
 A problem internal to GDB has been detected,

This patch teaches GDB to track FP registers (D registers) in prologue
analyzer.

Yao Qi b6542f81d0 Support displaced stepping in aarch64-linux
This patch is to support displaced stepping in aarch64-linux.  A
visitor is implemented for displaced stepping, and used to record
information to fixup pc after displaced stepping if needed.  Some
emit_* functions are converted to macros, and moved to
arch/aarch64-insn.{c,h} so that they can be shared.

Maxim Ostapenko 9f2e07213a Fix GDB build fail on Aarch64 when -fno-common is enabled
Current trunk GDB (and gdb-7.8.1 too) fails to build on Aarch64 when
-fno-common is enabled.  It fails during link stage due to multiple
definition of `tdesc_aarch64':

...
[  199s] aarch64-linux-nat.o: In function `initialize_tdesc_aarch64':
[  199s]
/home/abuild/rpmbuild/BUILD/gdb-7.8.1/gdb/features/aarch64.c:11:
multiple definition of `tdesc_aarch64'
[  199s]
aarch64-tdep.o:/home/abuild/rpmbuild/BUILD/gdb-7.8.1/gdb/objfiles.h:540:
first defined here
[  199s] aarch64-linux-nat.o: In function `initialize_tdesc_aarch64':
[  199s]
/home/abuild/rpmbuild/BUILD/gdb-7.8.1/gdb/features/aarch64.c:11:
multiple definition of `tdesc_aarch64'
[  199s]
aarch64-tdep.o:/home/abuild/rpmbuild/BUILD/gdb-7.8.1/gdb/objfiles.h:540:
first defined here
[  199s] collect2: error: ld returned 1 exit status
[  199s] make[2]: *** [gdb] Error 1
...

This happens because struct target_desc *tdesc_aarch64 is defined in
gdb/features/aarch64.c, which is included by two files
(gdb/aarch64-linux-nat.c and gdb/aarch64-tdep.c).

Andreas Arnez a069a2bdab AARCH64: Replace regset_alloc() invocations by static regset structures.
After removal of the regset_alloc invocations, the tdep fields
'gregset' and 'fpregset' become obsolete and are thus removed.
