[ARC] Fix conditional move contstraint · 27ffcc36

Move pattern (movsi_insn) allows predicated instructions to be
instructions which can hold all registers.  However, the conditional
variant doesn't.  This patch fixes this problem.

[ARC] Handle complex PIC move patterns. · 14555394

fwprop step is placing in the REG_EQUIV notes constant pic unspecs
expressions.  Then, loop may use these notes for optimizations
rezulting in complex patterns that are not supported by the current
implementation.

The patch adds handling of complex PIC addresses having MINUS or UNARY
operations.

rs6000, testsuite: Correct the broken_cplxf_arg test · 3079b92e

check_effective_target_broken_cplxf_arg is buggy.  It actually tests
if passing complex float works, not if it fails.  Also, it only runs
the test for target powerpc64-linux, but we are biarch, so it should
be powerpc*-linux.

This also changes the early-out conditions to be separate, because
the big combined condition was hard to follow.

This fixes the libstdc++ tests:

Running target unix/-m64
XPASS: 26_numerics/complex/13450.cc execution test
XPASS: 26_numerics/complex/pow.cc execution test
XPASS: 26_numerics/complex/value_operations/1.cc execution test

which were the last failing libstdc++ tests on BE.


gcc/testsuite/
	* lib/target-supports.exp (check_effective_target_broken_cplxf_arg):
	Fix test.  Make early-out condition return early.  Correct comments.

rs6000: float128 on BE and 32-bit · 7502c597

This fixes float128 on BE and on 32-bit.

The configure tests need to use -mabi=altivec for 32-bit, since it is
not the default there.  That also enables the "vector" keyword, used by
the tests.  To do this it temporarily adds a few flags to the CFLAGS
variable.

It also fixes a syntax error in the libgcc_cv_powerpc_float128_hw test
(the function name was missing in the function declaration).

Regenerating config.in (via autoreconf) removed the duplicate definition
of HAVE_SOLARIS_CRTS.

Finally, this adds a "-mfloat128-hardware requires -m64" test to
rs6000.c: all the current patterns need 64-bit registers.  Maybe we'll
want to add float128 hardware support to 32-bit some day, but certainly
not today.


	* config/rs6000/rs6000.c (rs6000_option_override_internal): Disallow
	-mfloat128-hardware without -m64.

libgcc/
	* configure.ac (test for libgcc_cv_powerpc_float128): Temporarily
	modify CFLAGS.  Add -mabi=altivec -mvsx -mfloat128.
	(test for libgcc_cv_powerpc_float128_hw): Add -mpower9-vector and
	-mfloat128-hardware to the CFLAGS.  Fix syntax error in the C snippet.
	* configure: Regenerate.
	* config.in: Regenerate.
