Sandeep Patel 3f23601b00 Branches must be the last instruction in a Thumb2 IT block. Approved by Evan Cheng.

Dan Gohman c9af381df8 Make CodePlacementOpt align loops, rather than loop headers. The 
header is just the entry block to the loop, and it needn't be at
the top of the loop in the code layout.

Remove the code that suppressed loop alignment for outer loops,
so that outer loops are aligned.

Evan Cheng 2f61e0946a When LiveVariables is adding implicit-def to model "partial dead", add the earlyclobber marker if the superreg def has it.

Dan Gohman 03a7667349 Fix this test to account for a movl $0 being emitted as an xor now, 
and convert it to FileCheck.

Bob Wilson 3b51560ae4 Revise ARM inline assembly memory operands to require the memory address to 
be in a register.  The previous use of ARM address mode 2 was completely
arbitrary and inappropriate for Thumb.  Radar 7137468.

Sandeep Patel 423e42b371 Add ARMv6T2 SBFX/UBFX instructions. Approved by Anton Korobeynikov.

Dan Gohman a698d7ac3c Don't forget to mark RAX as live-out of the function when arranging for 
it to hold the address of an sret return value, for x86-64 ABI purposes.

Also, fix the test that was originally intended to test this to actually
test it, using FileCheck.

 2009-10-11 19:14:21 +00:00
Anton Korobeynikov 5b8826b4da It seems that OR operation does not affect status reg at all. 
Remove impdef of SRW. This fixes PR4779

llvm-svn: 83739
 2009-10-10 22:17:47 +00:00
Dan Gohman 50998f4584 Update this test; the code is the same but it gets counted as one 
fewer remat.

llvm-svn: 83690
 2009-10-09 23:31:04 +00:00
Dan Gohman 7d9dffb413 Fix the x86 test-shrink optimization so that it doesn't shrink comparisons 
when one of the bits being tested would end up being the sign bit in the
narrower type, and a signed comparison is being performed, since this would
change the result of the signed comparison. This fixes PR5132.
