2011-12-05Add a little heuristic to Value::isUsedInBasicBlock to speed it up for small ↵Benjamin Kramer
basic blocks. - Calling getUser in a loop is much more expensive than iterating over a few instructions. - Use it instead of the open-coded loop in AddrModeMatcher. - 5% speedup on ARMDisassembler.cpp Release builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145810 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-03Add a "seen blocks" cache to LVI to avoid a linear scan over the whole cache ↵Benjamin Kramer
just to remove no blocks from the maps. -15% on ARMDisassembler.cpp (Release build). It's not that great to add another layer of caching to the caching-heavy LVI but I don't see a better way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145770 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-03Check for stack space more intelligently.Sanjoy Das
libgcc sets the stack limit field in TCB to 256 bytes above the actual allocated stack limit. This means if the function's stack frame needs less than 256 bytes, we can just compare the stack pointer with the stack limit. This should result in lesser calls to __morestack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145766 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-03Fix a bug in the x86-32 code generated for segmented stacks.Sanjoy Das
Currently LLVM pads the call to __morestack with a add and sub of 8 bytes to esp. This isn't correct since __morestack expects the call to be followed directly by a ret. This commit also adjusts the relevant test-case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145765 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-03Creating multiple JITs on X86 in multiple threads causes multiple writes (ofNick Lewycky
the same value) to this variable. This code could be refactored, but it doesn't matter since the old JIT is going away. Add tsan annotations to ignore the race. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145745 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
