llvm-svn: 89586
 2009-11-22 12:50:05 +00:00
Edward O'Callaghan 15dd46215e Convert a few tests to FileCheck for PR5307.

Jim Grosbach e09e95b35c Revert 89562. We're being sneakier than I was giving us credit for, and this 
isn't necessary.

Jim Grosbach 43fd822249 Darwin requires a frame pointer for all non-leaf functions to support correct 
backtraces.

Dale Johannesen b91eba382d When generating a vector the really slow way, via loads 
and stores, handle the case where the element size is not
a valid target type correctly (PPC).

Thanks to Daniel Dunbar for fixing clang intrinsics:

llvm-svn: 89500
 2009-11-20 22:28:42 +00:00
Dale Johannesen 8495a506eb Remove an incorrect overaggressive optimization 
(PPC specific).

Sean Callanan 19d92728d0 Reverting PALIGNR fix until I figure out how this 
broke the Clang testsuite.

llvm-svn: 89495
 2009-11-20 22:09:28 +00:00
Sean Callanan fbed130173 Fixed PALIGNR to take 8-bit rotations in all cases. 
Also fixed the corresponding testcase, and the PALIGNR
  intrinsic (tested for correctness with llvm-gcc).

Evan Cheng bdb43a9d99 Remat VLDRD from constpool. Clean up some instruction property specifications.

Duncan Sands cc0a0cb4b7 Fix PR5558, which was caused by a wrong fix for PR3393 (see commit 63048), 
which was an expensive checks failure due to a bug in the checking.  This
patch in essence reverts the original fix for PR3393, and refixes it by a
tweak to the way expensive checking is done.

Dan Gohman 20c8ab655e Fix fast-isel to avoid selecting the return instruction if a 
tail call has been encountered.

Bruno Cardoso Lopes 4713b282ce - Add sugregister logic to handle f64=(f32,f32). 
- Support mips1 like load/store of doubles:

Instead of:
  sdc $f0, X($3)
Generate:
  swc $f0, X($3)
  swc $f1, X+4($3)

Bill Wendling 77f0ea6b93 Test from Dhrystone to make sure that we're not emitting an aligned load for a 
string that's aligned at 8-bytes instead of 16-bytes.

Bob Wilson 108aadf972 Tail duplication still needs to iterate. Duplicating new instructions onto 
the tail of a block may make that block a new candidate for duplication.

Jakob Stoklund Olesen 575c3f3d72 Fix PR5300. 
When TwoAddressInstructionPass deletes a dead instruction, make sure that all
register kills are accounted for. The 2-addr register does not get special
treatment.

Jakob Stoklund Olesen fffff88a3c Enable -split-phi-edges by default, except when -regalloc=local. 
The local register allocator doesn't like it when LiveVariables is run.
We should also disable edge splitting under -O0, but that has to wait a bit.

Dan Gohman b43e1ff236 Fix this test - there don't appear to be any actual Reload Reuses 
in this testcase.

Dan Gohman 9dede3b383 Revert r87049, which was the workaround for the regression triggered 
by the recent FixedStackPseudoSourceValue-related changes, now that
the specific bug that affected it is fixed, in r88954.

Evan Cheng f25ef4ffb0 - Check memoperand alignment instead of checking stack alignment. Most load / store folding instructions are not referencing spill stack slots.

David Greene 25905c8336 Support spill comments. 
Have the asm printer emit a comment if an instruction is a spill or
reload and have the spiller mark copies it introdues so the asm printer
can also annotate those.

Bruno Cardoso Lopes 537e409c58 - Fix a small bug while handling target constant pools (one param was missing). 
- Add a smarter constant pool loading, instead of:

lui $2, %hi($CPI1_0)
addiu $2, $2, %lo($CPI1_0)
lwc1 $f0, 0($2)

Generate:

lui $2, %hi($CPI1_0)
lwc1 $f0, %lo($CPI1_0)($2)

Jim Grosbach 01c1cae34d Detect need for autoalignment of the stack earlier to catch spills more 
conservatively. eliminateFrameIndex() machinery adjust to handle addr mode
6 (vld1/vst1) used for spills. Fix tests to expect aligned Q-reg spilling
