2010-12-20New cmake option LLVM_APPEND_VC_REV for controlling when the VCOscar Fuentes
revision id is appended to the LLVM version string. Defaults to OFF. Until now the VC revision id was always appended to the revision string whenever cmake was invoked (either explicitly or implicitly because a cmake source file changed). This was causing massive recompilations because config.h are reconfigured with the new contents of PACKAGE_VERSION. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122240 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-20fix PR8769, a miscompilation by inliner when inlining a function with a byvalChris Lattner

2010-12-20implement type legalization promotion support for SMULO and UMULO, giving Chris Lattner
ARM (and other 32-bit-only) targets support for i8 and i16 overflow multiplies. The generated code isn't great, but this at least fixes CodeGen/Generic/overflow.ll when running on ARM hosts. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122221 91177308-0d34-0410-b5e6-96231b3b80d8

the same as setcc. Optimize ADDC(0,0,FLAGS) -> SET_CARRY(FLAGS). This is a step towards finishing off PR5443.

2010-12-20Change the X86 backend to stop using the evil ADDC/ADDE/SUBC/SUBE nodes (whichChris Lattner
their carry depenedencies with MVT::Flag operands) and use clean and beautiful EFLAGS dependences instead. We do this by changing the modelling of SBB/ADC to have EFLAGS input and outputs (which is what requires the previous scheduler change) and change X86 ISelLowering to custom lower ADDC and friends down to X86ISD::ADD/ADC/SUB/SBB nodes. With the previous series of changes, this causes no changes in the testsuite, woo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122213 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-20Fix a bug in the scheduler's handling of "unspillable" vregs.Chris Lattner
Imagine we see: EFLAGS = inst1 EFLAGS = inst2 FLAGS gpr = inst3 EFLAGS Previously, we would refuse to schedule inst2 because it clobbers the EFLAGS of the predecessor. However, it also uses the EFLAGS of the predecessor, so it is safe to emit. SDep edges ensure that the right order happens already anyway. This fixes 2 testsuite crashes with the X86 patch I'm going to commit next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122211 91177308-0d34-0410-b5e6-96231b3b80d8
