2012-02-16Use the same CALL instructions for Windows as for everything else.Jakob Stoklund Olesen
The different calling conventions and call-preserved registers are represented with regmask operands that are added dynamically. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150708 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-16Enable register mask operands for x86 calls.Jakob Stoklund Olesen
Call instructions no longer have a list of 43 call-clobbered registers. Instead, they get a single register mask operand with a bit vector of call-preserved registers. This saves a lot of memory, 42 x 32 bytes = 1344 bytes per call instruction, and it speeds up building call instructions because those 43 imp-def operands no longer need to be added to use-def lists. (And removed and shifted and re-added for every explicit call operand). Passes like LiveVariables, LiveIntervals, RAGreedy, PEI, and BranchFolding are significantly faster because they can deal with call clobbers in bulk. Overall, clang -O2 is between 0% and 8% faster, uniformly distributed depending on call density in the compiled code. Debug builds using clang -O0 are 0% - 3% faster. I have verified that this patch doesn't change the assembly generated for the LLVM nightly test suite when building with -disable-copyprop and -disable-branch-fold. Branch folding behaves slightly differently in a few cases because call instructions have different hash values now. Copy propagation flushes its data structures when it crosses a register mask operand. This causes it to leave a few dead copies behind, on the order of 20 instruction across the entire nightly test suite, including SPEC. Fixing this properly would require the pass to use different data structures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150638 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-02Move global variables in TargetMachine into new TargetOptions class. As an APINick Lewycky
change, now you need a TargetOptions object to create a TargetMachine. Clang patch to follow. One small functionality change in PTX. PTX had commented out the machine verifier parts in their copy of printAndVerify. That now calls the version in LLVMTargetMachine. Users of PTX who need verification disabled should rely on not passing the command-line flag to enable it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145714 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-28Clean up the handling of the x87 fp stack to make it more robust.Jakob Stoklund Olesen
Drop the FpMov instructions, use plain COPY instead. Drop the FpSET/GET instruction for accessing fixed stack positions. Instead use normal COPY to/from ST registers around inline assembly, and provide a single new FpPOP_RETVAL instruction that can access the return value(s) from a call. This is still necessary since you cannot tell from the CALL instruction alone if it returns anything on the FP stack. Teach fast isel to use this. This provides a much more robust way of handling fixed stack registers - we can tolerate arbitrary FP stack instructions inserted around calls and inline assembly. Live range splitting could sometimes break x87 code by inserting spill code in unfortunate places. As a bonus we handle floating point inline assembly correctly now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134018 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-25Rewrite fast-isel integer cast handling to handle more cases, and to be ↵Eli Friedman
simpler and more consistent.
