Daniel Sanders [Wed, 16 Jul 2014 15:34:07 +0000 (15:34 +0000)]
[mips][fp64a] Temporarily disable odd-numbered double-precision registers when using the FP64A ABI.

Summary:
A few instructions (mostly cvt.d.w and similar) are causing problems with
-mfp64 and -mno-odd-spreg and it looks like fixing it properly may
take several weeks. In the meantime, let's disable the odd-numbered
double-precision registers so that the generated code is at least valid.

The problem is that instructions like cvt.d.w read from the 32-bit low
subregister of a double-precision FPU register. This often leads to the compiler
to inserting moves to transfer a GPR32 to a FGR32 using mtc1. Such moves
violate the rules against 32-bit writes to odd-numbered FPU registers imposed
by -mno-odd-spreg. By disabling the odd-numbered double-precision registers, it
becomes impossible for the 32-bit low subregister to be odd-numbered.

This fixes numerous test-suite failures when compiling for the FP64A ABI
('-mfp64 -mno-odd-spreg'). There is no LLVM test case because it's difficult to
test that odd-numbered FPU registers are not allocatable. Instead, we depend on
the assembler (GAS and -fintegrated-as) raising errors when the rules are
violated.

[X86] Add a check for 'isMOVHLPSMask' within method 'isShuffleMaskLegal'.

Before this change, method 'isShuffleMaskLegal' didn't know that shuffles

This patch adds the missing check for 'isMOVHLPSMask' inside method
'isShuffleMaskLegal' to fix the problem.

The reason why it is important to do this is because the DAGCombiner
conservatively avoids combining a pair of shuffles if the resulting shuffle
node has an illegal mask. Before this patch, shuffles with a MOVHLPS mask were

[DAGCombiner] Add more rules to fold shuffles.

This patch adds two new rules to the DAGCombiner:
 1.  shuffle (shuffle A, Undef, M0), B, M1 -> shuffle A, B, M2
 2.  shuffle (shuffle A, Undef, M0), A, M1 -> shuffle A, Undef, M2

We only do this if the combined shuffle is legal for the target.

Example:
;;
define <4 x float> @test(<4 x float> %a, <4 x float> %b) {
  %1 = shufflevector <4 x float> %a, <4 x float> undef, <4 x i32><i32 6, i32 0, i32 1, i32 7>
  %2 = shufflevector <4 x float> %1, <4 x float> %b, <4 x i32><i32 1, i32 2, i32 4, i32 5>
  ret <4 x i32> %2
}

Revert "Revert "Move clang feature flags settings out of LLVM core and into cfe""

It turns out this commit was fine. The problem was in the legacy build system (fixed r213010).

This reverts commit r213005.

COFF lacks a feature that other object file formats support: mergeable
sections.

To work around this, MSVC sticks constant pool entries in special COMDAT
sections so that each constant is in it's own section.  This permits
unused constants to be dropped and it also allows duplicate constants in

[DAGCombiner] Add more rules to combine shuffle vector dag nodes.

This patch teaches the DAGCombiner how to fold a pair of shuffles
according to rules:
  1.  shuffle(shuffle A, B, M0), B, M1) -> shuffle(A, B, M2)
  2.  shuffle(shuffle A, B, M0), A, M1) -> shuffle(A, B, M3)

The new rules would only trigger if the resulting shuffle has legal type and
legal mask.

Added test 'combine-vec-shuffle-3.ll' to verify that DAGCombiner correctly
folds shuffles on x86 when the resulting mask is legal. Also added some negative
cases to verify that we avoid introducing illegal shuffles.

Support: Fix option handling when using cl::Required with aliasopt

Until now, attempting to create an alias of a required option would
complain if the user supplied the alias, because the required option
didn't have a value. Similarly, if you said the alias was required,
then using the base option would complain that the alias wasn't
supplied. Lastly, if you put required on both, *neither* option would
work.

By changning alias to overload addOccurrence and setting cl::Required
on the original option, we can get this to behave in a more useful
way. I've also added a test and updated a user that was getting this
