2007-06-02Integrate exception filter support and exception catch support. ThisDuncan Sands
simplifies the code in DwarfWriter, allows for multiple filters and makes it trivial to specify filters accompanied by cleanups or catch-all specifications (see next patch). What a deal! Patch blessed by Anton. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37398 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-01Since TypeInfos are passed as i8 pointers, a NULL TypeInfo should be passedDuncan Sands
as a null i8 pointer not as a 0 i32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37383 91177308-0d34-0410-b5e6-96231b3b80d8

2007-05-19Disable the (A == (B-A)) -> 2*A == B xform when the sub has multiple uses (inChris Lattner
this case, the xform introduces an extra operation). This compiles PowerPC/compare-duplicate.ll into: _test: subf r2, r3, r4 cmplw cr0, r2, r3 bne cr0, LBB1_2 ;F instead of: _test: slwi r2, r3, 1 subf r3, r3, r4 cmplw cr0, r4, r2 bne cr0, LBB1_2 ;F This is target independent of course. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37246 91177308-0d34-0410-b5e6-96231b3b80d8

Implement support for expanding a bitcast from an illegal vector type to a legal one (e.g. 4xi32 -> 4xf32 in SSE1). This fixes PR1371 and CodeGen/X86/2007-05-05-VecCastExpand.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36787 91177308-0d34-0410-b5e6-96231b3b80d8
