Rasmus Villemoes 92a7f46b09 fixincludes: vxworks: regs.h: Fix includes in regs.h wrapper
A quick experiment reveals that this hack is needed for C code - simply
removing this hack entirely breaks the build of libstdc++, since
regs.h (more accurately, the cpu-specific header it pulls in) defines
structs in terms of types from vxTypesOld. Those definitions are
properly guarded by #ifndef _ASMLANGUAGE, but the cpu-files do not take
care to include vxTypesOld.h for the types they depend on.

But when using regs.h from some assembly file, the assembler chokes on
the typedefs in vxTypesOld.h. We can fix that by guarding the include of
vxTypesOld by !_ASMLANGUAGE. This should not affect existing C code.

Now, the OS' regs.h contains preprocessor conditionals such as

#if     CPU_FAMILY==I960
...
#endif  /* CPU_FAMILY==I960 */
#if     CPU_FAMILY==MC680X0
...
#endif  /* CPU_FAMILY==MC680X0 */

Without definitions of CPU_FAMILY, I960 etc., these would all be true,
which will not end well. Code using the fix-included regs.h
automatically get vxCpu.h via a chain of includes from vxTypesOld.h, but
we can make regs.h a little more self-contained for both C and asm users
by doing an explicit include of vxCpu.h.

David Malcolm 0141ab44c5 diagnostics: add minimum width to left margin for line numbers
This patch adds a minimum width to the left margin used for printing
line numbers.   I set the default to 6.  Hence rather than:

some-filename:9:1: some message
9 | some source text
  | ^~~~~~~~~~~~~~~~
some-filename:10:1: another message
10 | more source text
   | ^~~~~~~~~~~~~~~~

we now print:

some-filename:9:42: some message
    9 | some source text
      | ^~~~~~~~~~~~~~~~
some-filename:10:42: another message
   10 | more source text
      | ^~~~~~~~~~~~~~~~

This implicitly fixes issues with margins failing to line up due
to different lengths of the number when we haven't read the full
file yet and so don't know the highest possible line number, for
line numbers up to 99999.

Doing so adds some whitespace on the left-hand side, for non-huge
files, at least.  I believe that this makes it easier to see where each
diagnostic starts, by visually breaking things up at the leftmost
column; my hope is to make it easier for the eye to see the different
diagnostics as if they were different "paragraphs".

	* common.opt (fdiagnostics-minimum-margin-width=): New option.

It would be preferable to use #pragma GCC diagnostic warning "-Wabi=12"

Wilco Dijkstra 0cfc095c8d [AArch64] Support zero-extended move to FP register
The popcount expansion uses SIMD instructions acting on 64-bit values.
As a result a popcount of a 32-bit integer requires zero-extension before 
moving the zero-extended value into an FP register.  This patch adds
support for zero-extended int->FP moves to avoid the redundant uxtw.
Similarly, add support for 32-bit zero-extending load->FP register
and 32-bit zero-extending FP->FP and FP->int moves.
Add a missing 'fp' arch attribute to the related 8/16-bit pattern and
fix an incorrect type attribute.

To complete zero-extended load support, add a new alternative to 
load_pair_zero_extendsidi2_aarch64 to support LDP into FP registers too.

int f (int a)
{
  return __builtin_popcount (a);
}

Before:
	uxtw	x0, w0
	fmov	d0, x0
	cnt	v0.8b, v0.8b
	addv	b0, v0.8b
	fmov	w0, s0
	ret

After:
	fmov	s0, w0
	cnt	v0.8b, v0.8b
	addv	b0, v0.8b
	fmov	w0, s0
	ret

Passes regress & bootstrap on AArch64.

	* config/aarch64/aarch64.md (zero_extendsidi2_aarch64): Add alternatives
	to zero-extend between int and floating-point registers.
	(load_pair_zero_extendsidi2_aarch64): Add alternative for zero-extended

	(zero_extend<SHORT:mode><GPI:mode>2_aarch64): Add arch attribute.
