f39c07acc8 Cast the pointer assigned to ss_sp to char *.
FreeBSD versions older than 11.0 use char * as the type of ss_sp in
stack_t instead of the standards-defined void *.  C++ allows a char *
pointer to be converted to a void *, so it is safe to cast the return
value of xmalloc to char * if ss_sp is either a char * or void *.
Just always use the cast to char * since that is less ugly than having
to add a special case.

gdb/ChangeLog:

	* main.c (setup_alternate_signal_stack): Cast to char *.

f42bf748e4 Re-factor (i386|amd64)mpx target descriptions.
In the previous patch a new set of target descriptions
(i386|amd64)-avx-mpx were added  being same as the (i386|amd64)-mpx.
This patch removes AVX feature from  (i386|amd64)-mpx target
description set.

This way the (i386|amd64)avx_mpx(_linux|) set has AVX and MPX features
and (i386|amd64)mpx(_linux|) only MPX.

2b863f512d Add target descriptions for AVX + MPX
The current MPX target descriptions assume that MPX is always combined
with AVX, however that's not correct.  We can have machines with MPX
and without AVX; or machines with AVX and without MPX.

This patch adds new target descriptions for machines that support
both MPX and AVX, as duplicates of the existing MPX descriptions.

The following commit will remove AVX from the MPX-only descriptions.

9b30624b65 Fix PR gdb/19250: ptrace prototype is not detected properly in C++ mode
The ptrace args/return types detection doesn't work properly in C++
mode, on non-GNU/Linux hosts.  For example, on gcc70 (NetBSD 5.1),
where the prototype is:

 int ptrace(int, __pid_t, void*, int);

configure misdetects it as:

 $ grep PTRACE_TYPE config.h
 #define PTRACE_TYPE_ARG1 int
 #define PTRACE_TYPE_ARG3 int *
 #define PTRACE_TYPE_ARG4 int
 /* #undef PTRACE_TYPE_ARG5 */
 #define PTRACE_TYPE_RET int

resulting in:

 ../../src/gdb/amd64bsd-nat.c: In function 'void amd64bsd_fetch_inferior_registers(target_ops*, regcache*, int)':
 ../../src/gdb/amd64bsd-nat.c:56: warning: dereferencing type-punned pointer will break strict-aliasing rules
 ../../src/gdb/amd64bsd-nat.c: In function 'void amd64bsd_store_inferior_registers(target_ops*, regcache*, int)':
 ../../src/gdb/amd64bsd-nat.c:104: warning: dereferencing type-punned pointer will break strict-aliasing rules
 ../../src/gdb/amd64bsd-nat.c:110: warning: dereferencing type-punned pointer will break strict-aliasing rules

We could address this [1], however despite ptrace.m4's claim:

 # Needs to be tested in C++ mode, to detect whether we need to cast
 # the first argument to enum __ptrace_request.

it appears that there's actually no need to test in C++ mode.  Always
running the ptrace tests in C mode works just the same on GNU/Linux.

I remember experimenting with several different ways to handle the
original issue back then, and maybe that was needed in some other
attempt and then I didn't realize it ended up not really necessary.

Confirmed that this fixes the NetBSD 5.1 C++ build, and confirmed that
C and C++ builds on Fedora 23 are unaffected.

a22df60ad2 Fix gdb crash when trying to print the address of a synthetic C++ reference
After compiling a program which uses C++ references some optimizations may
convert the references into synthetic "pointers".  Trying to print the address
of one of such synthetic references causes gdb to crash with the following
error:

(gdb) print &ref
/build/buildd/gdb-7.7.1/gdb/dwarf2loc.c:1624: internal-error: Should not be able to create a lazy value with an enclosing type
A problem internal to GDB has been detected,
further debugging may prove unreliable.

Apparently, what was causing it was that value_addr returns a copy of the value
that represents the reference with its type set to T* instead of T&.  However,
its enclosing_type is left untouched, which fails a check made in
read_pieced_value.  We only see the crash happen for references that are
synthetic because they're treated as pieced values, thus the call to
read_pieced_value.

On a related note, it seems that in general there are all sorts of breakage
when working with synthetic references.  This is reported here:

92fce9bd7a remove pointless assignment
Presumably this was supposed to be regname[sizeof (regname) - 1] but was typoed
to regname[sizeof (rename) - 1].  However that should be unnecessary because
sprintf should null terminate.  As is this assignment is invalid ISO C because
rename refers to the function rename (), and sizeof on functions is undefined.
In GNU C C the size of functions is 1 so the expression is the same as
regname[0].  The following call to sprintf () clearly will over right that, so
the statement either has no effect or is invalid.  Given that it seems safe to
just remove it.  While we are there correct the size of regname, and switch
from snprintf to sprintf since we know the exact length of the result.

 ../../src/gdb/d-exp.y:762: multiple definition of `yydefred'
 ada-exp.o:/home/palves/gdb/build/gdb/ada-lex.c:925: first defined here
 ld: Warning: size of symbol `yydefred' changed from 464 in ada-exp.o to 336 in d-exp.o
 Makefile:1404: recipe for target 'gdb' failed

NetBSD's yacc uses a "yydefred" symbol that we missed renaming in the
Ada parser.  All other gdb parsers do this already.

2016-04-16  Pedro Alves  <palves@redhat.com>

	* ada-exp.y (yydefred): Define as ada_yydefred.

77770d8321 MIPS/Linux: Also recognize TRAP_BRKPT and TRAP_HWBKPT
This makes the MIPS Linux backends recognize TRAP_BRKPT and
TRAP_HWBKPT in siginfo.si_code in addition to SI_KERNEL, since Linux
4.6 now reports the finer-grained si_code values too.

Refs:
 https://sourceware.org/ml/gdb-patches/2016-02/msg00756.html
 https://sourceware.org/ml/gdb-patches/2016-04/msg00090.html

On kernels that report SI_KERNEL (<= 4.5), we'll enter the "ambiguous"
path of save_stop_reason:

	  if (GDB_ARCH_IS_TRAP_BRKPT (siginfo.si_code)
	      && GDB_ARCH_IS_TRAP_HWBKPT (siginfo.si_code))
	    {
	      /* The si_code is ambiguous on this arch -- check debug
		 registers.  */
	      if (!check_stopped_by_watchpoint (lp))
		lp->stop_reason = TARGET_STOPPED_BY_SW_BREAKPOINT;
	    }

while on kernels that report the finer-grained si_code values (>= 4.6),
we'll enter the corresponding branches:

	  else if (GDB_ARCH_IS_TRAP_BRKPT (siginfo.si_code))
	    {
	    }
	  else if (GDB_ARCH_IS_TRAP_HWBKPT (siginfo.si_code))
	    {
	      ...

gdb/ChangeLog:

	* nat/linux-ptrace.h [__mips__] (GDB_ARCH_IS_TRAP_BRKPT): Also

415fa61233 [ARM] minor opt in thumb_stack_frame_destroyed_p
thumb_stack_frame_destroyed_p scans the instructions from PC to the
end of the function, but if PC is far from the end of pc, we don't
have to scan, because PC should be in epilogue if it is still
far from the end of the function.  The criterion I use here is 16
bytes, which is more than 4 instructions.

Regression tested on aarch64-linux with mutli-arch debug.

4b0c052e45 arc/nps400 : New cmem instructions and associated relocation
Add support for arc/nps400 cmem instructions, these load and store
instructions are hard-wired to access "0x57f00000 + 16-bit-offset".

Supporting this relocation required some additions to the arc relocation
handling in the bfd library, as well as the standard changes required to
add a new relocation type.

There's a test of the new instructions in the assembler, and a test of
the relocation in the linker.

	* reloc.c: Add BFD_RELOC_ARC_NPS_CMEM16 entry.

33cbe6c07e bfd/arc: Rename enum entries to avoid conflicts
In bfd/elf32-arc.c an enum is created that contains entries with generic
names like 'NONE' and 'OFF'.  This has been fine for now, but I had a
need to include opcode/arc.h into bfd/elf32-arc.c.  Unfortunately
opcode/arc.h includes a different enum with identical generic names.

Given that changing the enum in the header file could mean wide-ranging
changes, while changing the enum in the .c file is limited to only
changing the one file, I've added a prefix to the enum in the .c file.

This commit does not add the new include, that will come later.  There
should be no functional change with this commit.

bfd/ChangeLog:

	* elf32-arc.c (tls_got_entries): Add 'TLS_GOT_' prefix to all
	entries.
	(elf_arc_relocate_section): Update enum uses.
