d521906965 aarch64-linux process record: more syscalls 
The last patch supports several syscalls in linux-record.c, so now
GDB aarch64-linux backend can return these canonicalized syscall numbers
per aarch64 syscall number.

This patch fixes the following fails,

Process record and replay target doesn't support syscall number 59^M
Process record: failed to record execution log.^M
^M
Program stopped.^M
0x00000020000eab28 in pipe () from /lib/aarch64-linux-gnu/libc.so.6^M
(gdb) FAIL: gdb.reverse/pipe-reverse.exp: continue to breakpoint: marker2

c955ae7389 Process record for aarch64-linux syscall 
This patch updates the syscalls in sync with syscalls/aarch64-linux.xml.
Some syscalls are still not supported by gdb/linux-record.c yet.  Mark
them UNSUPPORTED_SYSCALL_MAP.

This patch fixes the following test fail,

72aded8673 gdb/linux-record: Fix readdir and getdents handling 
getdents buffer size is given in bytes, not dirent entries (which have
variable size anyway).  We don't need size_dirent and size_dirent64 for
this reason.

readdir, on the other hand, needs size of old_linux_dirent, which is
a somewhat different structure.  Accordingly, rename size_dirent
to size_old_dirent.

	* aarch64-linux-tdep.c (aarch64_linux_init_abi): Remove
	size_dirent{,64}, add size_old_dirent.

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.

224c3ddb89 Add casts to memory allocation related calls 
Most allocation functions (if not all) return a void* pointing to the
allocated memory.  In C++, we need to add an explicit cast when
assigning the result to a pointer to another type (which is the case
more often than not).

The content of this patch is taken from Pedro's branch, from commit
"(mostly) auto-generated patch to insert casts needed for C++".  I
validated that the changes make sense and manually reflowed the code to
make it respect the coding style.  I also found multiple places where I
could use XNEW/XNEWVEC/XRESIZEVEC/etc.

Thanks a lot to whoever did that automated script to insert casts, doing
it completely by hand would have taken a ridiculous amount of time.

Only files built on x86 with --enable-targets=all are modified.  This
means that all other -nat.c files are untouched and will have to be
dealt with later by using appropiate compilers.  Or maybe we can try to
build them with a regular g++ just to know where to add casts, I don't
know.

I built-tested this with --enable-targets=all and reg-tested.

Here's the changelog entry, which was not too bad to make despite the
size, thanks to David Malcom's script.  I fixed some bits by hand, but
there might be some wrong parts left (hopefully not).

f68f11b76d Support catch syscall on aarch64 linux 
Hi,
This patch is to support catch syscall on aarch64 linux.  We
implement gdbarch method get_syscall_number for aarch64-linux,
and add aarch64-linux.xml file, which looks straightforward, however
the changes to test case doesn't.

First of all, we enable catch-syscall.exp on aarch64-linux target,
but skip the multi_arch testing on current stage.  I plan to touch
multi arch debugging on aarch64-linux later.

Then, when I run catch-syscall.exp on aarch64-linux, gcc errors that
SYS_pipe isn't defined.  We find that aarch64 kernel only has pipe2
syscall and libc already convert pipe to pipe2.  As a result, I change
catch-syscall.c to use SYS_pipe if it is defined, otherwise use
SYS_pipe2 instead.  The vector all_syscalls in catch-syscall.exp can't
be pre-determined, so I add a new proc setup_all_syscalls to fill it,
according to the availability of SYS_pipe.

Regression tested on {x86_64, aarch64}-linux x {native, gdbserver}.

4108500a2a AARCH64: Migrate from 'regset_from_core_section' to 'iterate_over_regset_sections' 
Don't define the 'regset_from_core_section' method, but the iterator
method instead.  This slightly reduces the code and enables non-native
use of the 'generate-core-file' command.

Also, when all instances of 'regset_from_core_section' are replaced,
it can be dropped from the gdbarch interface.

d4d793bfeb AARCH64 Linux: Fill 'collect_regset' in regset structures. 
In order to provide 'collect_regset' support, the generic function
regcache_collect_regset is exploited.  Since this requires writing
appropriate register maps, these can be used for supply_regset as
well.

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.

f2205de008 Fix issue #15778: GDB Aarch64 signal frame unwinder issue 
The root cause of this issue is unwinder of "#3  <signal handler called>"
doesn't supply right values of registers.
When GDB want to get the previous frame of "#3  <signal handler called>",
it will call cache init function of unwinder "aarch64_linux_sigframe_init".
The address or the value of the registers is get from this function.
So the bug is inside thie function.

I check the asm code of "#3  <signal handler called>":
(gdb) frame 3
(gdb) p $pc
$1 = (void (*)()) 0x7f931fa4d0
(gdb) disassemble $pc, +10
Dump of assembler code from 0x7f931fa4d0 to 0x7f931fa4da:
=> 0x0000007f931fa4d0:	mov	x8, #0x8b                  	// #139
   0x0000007f931fa4d4:	svc	#0x0
   0x0000007f931fa4d8:	nop

This is the syscall sys_rt_sigreturn, Linux kernel function "restore_sigframe"
will set the frame:
	for (i = 0; i < 31; i++)
		__get_user_error(regs->regs[i], &sf->uc.uc_mcontext.regs[i],
				 err);
	__get_user_error(regs->sp, &sf->uc.uc_mcontext.sp, err);
	__get_user_error(regs->pc, &sf->uc.uc_mcontext.pc, err);
The struct of uc_mcontext is:
struct sigcontext {
	__u64 fault_address;
	/* AArch64 registers */
	__u64 regs[31];
	__u64 sp;
	__u64 pc;
	__u64 pstate;
	/* 4K reserved for FP/SIMD state and future expansion */
	__u8 __reserved[4096] __attribute__((__aligned__(16)));
};

But in GDB function "aarch64_linux_sigframe_init", the code the get address
of registers is:
  for (i = 0; i < 31; i++)
    {
      trad_frame_set_reg_addr (this_cache,
			       AARCH64_X0_REGNUM + i,
			       sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET
			       + i * AARCH64_SIGCONTEXT_REG_SIZE);
    }

  trad_frame_set_reg_addr (this_cache, AARCH64_FP_REGNUM, fp);
  trad_frame_set_reg_addr (this_cache, AARCH64_LR_REGNUM, fp + 8);
  trad_frame_set_reg_addr (this_cache, AARCH64_PC_REGNUM, fp + 8);

The code that get pc and sp is not right, so I change the code according
to Linux kernel code:
  trad_frame_set_reg_addr (this_cache, AARCH64_SP_REGNUM,
			   sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET
			     + 31 * AARCH64_SIGCONTEXT_REG_SIZE);
  trad_frame_set_reg_addr (this_cache, AARCH64_PC_REGNUM,
			   sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET
			     + 32 * AARCH64_SIGCONTEXT_REG_SIZE);

The issue was fixed by this change, and I did the regression test.  It
also fixed a lot of other XFAIL and FAIL.

410a0ff2df Remove `expout*' globals from parser-defs.h 
This commit removes the "expout*" globals from our parser code, turning
them into a structure that is passed when an expression needs to be
evaluated.  This is the initial step to make our parser less
"globalized".

This is mostly a mechanical patch, which creates a structure containing
the "expout*" globals and then modify all the functions that handle them
in order to take the structure as argument.  It is big, and has been
reviewed at least 4 times, so I think everything is covered.

08248ca9fe Implement SystemTap SDT probe support for AArch64 
This commit implements the needed bits for SystemTap SDT probe support
on AArch64 architectures.

First, I started by looking at AArch64 assembly specification and
filling the necessary options on gdbarch's stap machinery in order to
make the generic asm parser (implemented in stap-probe.c) recognize
AArch64's asm.

After my last patch for the SystemTap SDT API, which extends it in order
to accept multiple prefixes and suffixes, this patch became simpler.  I
also followed Marcus suggestion and did not shared code between 32- and
64-bit ARM.

Tom asked me in a previous message how I did my tests.  I believe I
replied that, but just in case: I ran the tests on
gdb.base/stap-probe.exp by hand.  I also managed to run the tests on
real hardware, and they pass without regressions.
