2010-09-23Follow up to r114630. Do not optimize away unconditional branch following a ↵Evan Cheng
conditional one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114634 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-23Disable codegen prepare critical edge splitting. Machine instruction passes nowEvan Cheng

2010-09-23If there are multiple unconditional branches terminating a block, eliminate allEvan Cheng
but the first one. Those will never be executed. There was logic to do this but it was faulty. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114632 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-23Don't sink insert_subreg, subreg_to_reg, reg_sequence. They are meant to beEvan Cheng
close to their sources to facilitate coalescing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114631 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-23SDISel should not optimize a unconditional branch following a conditional branchEvan Cheng
when the unconditional branch destination is the fallthrough block. The canonicalization makes it easier to allow optimizations on DAGs to invert conditional branches. The branch folding pass (and AnalyzeBranch) will clean up the unnecessary unconditional branches later. This is one of the patches leading up to disabling codegen prepare critical edge splitting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114630 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-23Moved the PBQP allocator class out of the header and back in to the cpp file ↵Lang Hames
to hide the gory details. Allocator instances can now be created by calling createPBQPRegisterAllocator. Tidied up use of CoalescerPair as per Jakob's suggestions. Made the new PBQPBuilder based construction process the default. The internal construction process remains in-place and available via -pbqp-builder=false for now. It will be removed shortly if the new process doesn't cause any regressions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114626 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-22Add support for ELF PLT references for ARM MC asm printing. Adding aJim Grosbach
new VariantKind to the MCSymbolExpr seems like overkill, but I'm not sure there's a more straightforward way to get the printing difference captured. (i.e., x86 uses @PLT, ARM uses (PLT)). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114613 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-22Change VDUPLANE DAG combiner to just return the result instead of callingBob Wilson
CombineTo to avoid putting the result on the worklist. I don't think it makes much difference for now, but it might help someday as we add more DAG combine optimizations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114595 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-22Fix an inconsistency in the x86 backend that led it to reject "calll foo" onChris Lattner
x86-32: 32-bit calls were named "call" not "calll". 64-bit calls were correctly named "callq", so this only impacted x86-32.
