* Silence VC++ redeclaration warnings.Jeff Cohen2005-09-291-4/+6

* Never rely on ReplaceAllUsesWith when selecting, use CodeGenMap instead.Chris Lattner2005-09-291-34/+29
| | | | | | | ReplaceAllUsesWith does not replace scalars SDOperand floating around on the stack, permitting things to be selected multiple times. llvm-svn: 23515

* Add FP versions of the binary operators, keeping the int and fp worlds seperate.Chris Lattner2005-09-284-97/+108
| | | | | | | | Though I have done extensive testing, it is possible that this will break things in configs I can't test. Please let me know if this causes a problem and I'll fix it ASAP. llvm-svn: 23505

| | | | | | and PR632. llvm-svn: 23484
* Darwin, like many BSD systems, has a setjmp/longjmp which saves the signal maskChris Lattner2005-09-271-0/+3
| | | | | | | | | on setjmp calls and restores it on longjmp calls (both of which require syscalls). This makes the calls REALLY slow. Use _setjmp/_longjmp instead. This speeds up hexxagon from 120.31s to 15.68s: from 5.53x slower than GCC to 28% faster than GCC. llvm-svn: 23482

* Completely rewrite 'correct' eh support. This changes how setjmp insertionChris Lattner2005-09-271-140/+301
| | | | | | | | | | | | | | | | | is performed so it is only at most once per function that contains an invoke instead of once per invoke in the function. This patch has the following perks: 1. It fixes PR631, which complains about slowness. 2. If fixes PR240, which complains about non-volatile vars being live across setjmp/longjmps. 3. It improves (but does not fix) the jmpbuf alignment issue on itanium by not forcing the jmpbufs to always be 8-bytes off the alignment of the structure. 4. It speeds up 253.perlbmk from 338s to 13.70s (a 25x improvement!), making us now about 4% faster than GCC. Further improvements are also possible. llvm-svn: 23477

This speeds up isa/dyncast/etc for constants, and also makes them smaller. For example, the text section of a release build of InstCombine.cpp shrinks from 230037 bytes to 216363 bytes, a 6% reduction. llvm-svn: 23467
