* Big change #1 for personality function references:Chris Lattner2009-09-164-9/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | Eliminate the PersonalityPrefix/Suffix & NeedsIndirectEncoding fields from MAI: they aren't part of the asm syntax, they are related to the structure of the object file. To replace their functionality, add a new TLOF::getSymbolForDwarfGlobalReference method which asks targets to decide how to reference a global from EH in a pc-relative way. The default implementation just returns the symbol. The default darwin implementation references the symbol through an indirect $non_lazy_ptr stub. The bizarro x86-64 darwin specialization handles the weird "foo@GOTPCREL+4" hack. DwarfException.cpp now uses this to emit the reference to the symbol in the right way, and this also eliminates another horrible hack from DwarfException.cpp: - if (strcmp(MAI->getPersonalitySuffix(), "+4@GOTPCREL")) - O << "-" << MAI->getPCSymbol(); git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81991 91177308-0d34-0410-b5e6-96231b3b80d8
* Added a variety of floating-point and SSE instructions.Sean Callanan2009-09-162-0/+51
| | | | | | | | | | | | | All of these do not have patterns (they're for the disassembler). Many of the floating-point instructions will probably be rolled into definitions that have patterns, and may eventually be superseded by mdefs. So I put them together and left a comment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81979 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | interrupt instruction, which shouldn't arise any other way). 0xcd is also used by JITMemoryManager to initialize the buffer to garbage, which means it could appear following a noreturn call even when that is not a stub, confusing X86CompilationCallback2.
