Benjamin Kramer	279e5cfa9a	Remove the old CodePlacementOpt pass. ... It was superseded by MachineBlockPlacement and disabled by default since LLVM 3.1. llvm-svn: 178349	2013-03-29 17:14:24 +00:00
Jakob Stoklund Olesen	8d6641a2b2	Disable code placement for this test. ... It makes it less sensitive to small changes in heuristics. llvm-svn: 154857	2012-04-16 20:49:06 +00:00
Lang Hames	5685c98688	Change the constant in this testcase so that it results in a constant pool ... load. llvm-svn: 153704	2012-03-29 23:52:38 +00:00
Jim Grosbach	4a2f107b04	ARM VLDR/VSTR instructions don't need a size suffix. ... Canonicallize on the non-suffixed form, but continue to accept assembly that has any correctly sized type suffix. llvm-svn: 144583	2011-11-14 23:03:21 +00:00
Jakob Stoklund Olesen	2611cc2520	Fix -widen-vmovs liveness issues. ... When widening a copy, we are reading a larger register that may not be live. Use an <undef> flag to tell the register scavenger and machine code verifier that we know the value isn't defined. We now widen: %S6<def> = COPY %S4<kill>, %D3<imp-def> into: %D3<def> = VMOVD %D2<undef>, pred:14, pred:%noreg, %S4<imp-use,kill> This also keeps the <kill> flag on %S4 so we don't inadvertently kill a live value in %S5. Finally, ensure that ARMBaseInstrInfo::setExecutionDomain() preserves the <undef> flag when converting VMOVD to VORR. llvm-svn: 141746	2011-10-12 00:06:23 +00:00
