2011-05-19Turns out GAS does have Win64 EH directives. (It also supports WinCE EH.) MakeCharles Davis
ours compatible with GAS. In retrospect, I should have emailed binutils about this earlier. Thanks to Kai Tietz for pointing out that GAS already had SEH directives. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131652 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131627 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-19Fix PR8828 by removing the explicit def in MovePCToLR as well as the pointlessCameron Zwarich
piclabel operand. The operand in the tablegen definition doesn't actually turn into an MI operand, so it just confuses anything checking the TargetInstrDesc for the number of operands. It suffices to just have an implicit def of LR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131626 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-19Implement the StartProc and EndProc Win64 EH methods on the base MCStreamer.Charles Davis
Based largely on Rafael Espindola's work on CFI. Other methods soon to follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131623 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-19Correctly constrain a register class when computing frame offsets, as the Thumb2Cameron Zwarich
add instruction takes an rGPR. This fixes the last of PR8825. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131619 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-19Revert r128961 because it didn't include a test and causes the verifier to failCameron Zwarich
on CodeGen/X86/2007-05-07-InvokeSRet.ll. There is probably a bug here that was fixed by r128961, but since there is no test or reference to a source file I have to revert it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131618 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-18When forming an ICmpZero LSRUse, normalize the non-IV operandDan Gohman
of the comparison, so that the resulting expression is fully normalized. This fixes PR9939. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131576 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-18Add some more Win64 EH directives:Charles Davis
- StartChained and EndChained delimit a chained unwind area, which can contain additional operations to be undone if an exception occurs inside of it. - UnwindOnly declares that this function doesn't handle any exceptions. If it has a handler, it's an unwind handler instead of an exception handler. - Lsda declares the location and size of the LSDA, which in the Win64 EH scheme is kept inside the UNWIND_INFO struct. Windows itself ignores the LSDA; it's used by the Language-Specific Handler (the "Personality Function" from DWARF). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131572 91177308-0d34-0410-b5e6-96231b3b80d8
