an instruction kills a register or not. This is cheap and easy to do now that instructions record this on their flags, and this eliminates the second pass of LiveVariables from the x86 backend. This speeds up a release llc by ~2.5%. llvm-svn: 45955

Actually were not riding any arguments. Sadly there is no semantic spell checker that is going to safe you from such a mistake. llvm-svn: 45868

commit all arguments where moved to the stack slot where they would reside on a normal function call before the lowering to the tail call stack slot. This was done to prevent arguments overwriting each other. Now only arguments sourcing from a FORMAL_ARGUMENTS node or a CopyFromReg node with virtual register (could also be a caller's argument) are lowered indirectly. --This line, and those below, will be ignored-- M X86/X86ISelLowering.cpp M X86/README.txt llvm-svn: 45867

both work right according to the new flags. This removes the TII::isReallySideEffectFree predicate, and adds TII::isInvariantLoad. It removes NeverHasSideEffects+MayHaveSideEffects and adds UnmodeledSideEffects as machine instr flags. Now the clients can decide everything they need. I think isRematerializable can be implemented in terms of the flags we have now, though I will let others tackle that. llvm-svn: 45843

x86 backend where instructions were not marked maystore/mayload, and perf issues where instructions were not marked neverHasSideEffects. It would be really nice if we could write patterns for copy instructions. I have audited all the x86 instructions down to MOVDQAmr. The flags on others and on other targets are probably not right in all cases, but no clients currently use this info that are enabled by default. llvm-svn: 45829

Do not use the stack pointer directly, issue a copyfromreg instead. Otherwise we can end up with something like ADD32ri %esp, x which two-address pass won't like. llvm-svn: 45798
