This patch teaches the backend how to combine packed SSE2/AVX2 arithmetic shift
intrinsics.

The rules are:
 - Always fold a packed arithmetic shift by zero to its first operand;
 - Convert a packed arithmetic shift intrinsic dag node into a ISD::SRA only if
   the shift count is known to be smaller than the vector element size.

This patch also teaches to function 'getTargetVShiftByConstNode' how fold
target specific vector shifts by zero.

Added two new tests to verify that the DAGCombiner is able to fold
sequences of SSE2/AVX2 packed arithmetic shift calls.

10 years ago[mips] Correct tests that are meant to test valid assembly. They were actually reject...
Daniel Sanders [Thu, 8 May 2014 15:17:29 +0000 (15:17 +0000)]
[mips] Correct tests that are meant to test valid assembly. They were actually rejected by GAS.

Summary:
I've noticed a bug in my test generator script that caused 64-bit objects
to be disassembled as if it were using the O32 ABI, giving the wrong register
names. As a result, it generated assembly files that are rejected by GAS when
assembling for the correct ABI. This was caused by the generator setting the
ELF e_flags incorrectly before disassembling the object.

This patch corrects the invalid tests that have already been committed by
replacing the ABI-dependent register names with numeric registers. In addition
to fixing the tests this allows the 32-bit and 64-bit ISA tests to be easily diffed
to produce the invalid-*.s tests which test that instructions defined in later ISA's
are not accepted.

For the moment, these instructions will follow GAS and accept them for
