Bruno Cardoso Lopes 96b11f39e2 Add AVX pattern versions for PSHUFB,PSIGN{B,W,D} 
llvm-svn: 139067
 2011-09-03 00:46:54 +00:00
Bruno Cardoso Lopes 9a0da1e57a Add AVX versions of MOVZDI2PDI patterns. Use SUBREG_TO_REG to indicate 
that the AVX versions (even the 128-bit ones) all clear the upper part
of the destination register.

Owen Anderson 40d756eacc Fix a truly heinous bug in DAGCombine related to AssertZext. 
If we have a chain of zext -> assert_zext -> zext -> use, the first zext would get simplified away because of the later zext, and then the later zext would get simplified away because of the assert.  The solution is to teach SimplifyDemandedBits that assert_zext demands all of the high bits of its input, rather than only those demanded by its users.  No testcase because the only example I have manifests as llvm-gcc miscompiling LLVM, and I haven't found a smaller case that reproduces this problem.
Fixes <rdar://problem/10063365>.

Jakob Stoklund Olesen 1f72dd40c7 Pseudo CMOV instructions don't clobber EFLAGS. 
The explanation about a 0 argument being materialized as xor is no
longer valid.  Rematerialization will check if EFLAGS is live before
clobbering it.

The code produced by X86TargetLowering::EmitLoweredSelect does not
clobber EFLAGS.

This causes one less testb instruction to be generated in the cmov.ll
test case.

Jakob Stoklund Olesen f08354d183 Check for EFLAGS live-out before clobbering it. 
It is only allowed to clobber EFLAGS at the end of a block if it isn't
live-in to any successor.

Jim Grosbach a0d34d3b5e Thumb2 parsing and encoding of B instruction. 
Tweak handling of IT blocks a bit to enable this. The differentiation between
B and Bcc needs special sauce.

Bill Wendling 73e6333ce1 No need to get fancy inserting a PHI node when the values are stored in stack 
slots. This fixes a bug where the number of nodes coming into the PHI node may
not equal the number of predecessors. E.g., two or more landingpad instructions
may require a PHI before reaching the eh.exception and eh.selector instructions.

Johnny Chen 1bd08dd878 Watchpoint work in progress: 
Add a virtual method GetHardwareWatchpointHit() to the DNBArchProtocol base class
which consults the architecture to return the watchpoint hit; otherwise return an
invalid index.

Add impl. of the method to X86_64 and I386 subclasses, plus reset the debug status
register before we resume execution of the inferior thread.

David Greene 09d153eb12 Make RecordVal Name an Init 
Store a RecordVal's name as an Init to allow class-qualified Record
members to reference Records that have Init names.  We'll use this to
provide more programmability in how we name defs and their associated
members.
