2007-08-04This is the patch to provide clean intrinsic function overloading support in ↵Chandler Carruth
LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future. This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40807 91177308-0d34-0410-b5e6-96231b3b80d8

2007-08-02Instead of adding copyfromreg's to handle physical definitions. Now isel canEvan Cheng
simply specify them as results and let scheduledag handle them. That is, instead of SDOperand Flag = DAG.getTargetNode(Opc, MVT::i32, MVT::Flag, ...) SDOperand Result = DAG.getCopyFromReg(Chain, X86::EAX, MVT::i32, Flag) Just write: SDOperand Result = DAG.getTargetNode(Opc, MVT::i32, MVT::i32, ...) And let scheduledag emit the move from X86::EAX to a virtual register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40710 91177308-0d34-0410-b5e6-96231b3b80d8

2007-07-14Long live the exception handling!Anton Korobeynikov
This patch fills the last necessary bits to enable exceptions handling in LLVM. Currently only on x86-32/linux. In fact, this patch adds necessary intrinsics (and their lowering) which represent really weird target-specific gcc builtins used inside unwinder. After corresponding llvm-gcc patch will land (easy) exceptions should be more or less workable. However, exceptions handling support should not be thought as 'finished': I expect many small and not so small glitches everywhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@39855 91177308-0d34-0410-b5e6-96231b3b80d8
