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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23505 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-28Emit an error if instructions or patterns are defined but can never match.Chris Lattner
Currently we check that immediate values live on the RHS of commutative operators. Defining ORI like this, for example: def ORI : DForm_4<24, (ops GPRC:$dst, GPRC:$src1, u16imm:$src2), "ori $dst, $src1, $src2", [(set GPRC:$dst, (or immZExt16:$src2, GPRC:$src1))]>; results in: tblgen: In ORI: Instruction can never match: Immediate values must be on the RHS of commutative operators! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23501 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-27Darwin, like many BSD systems, has a setjmp/longjmp which saves the signal maskChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23482 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-27Add a new flag for targets where setjmp/longjmp saves/restores the signal mask,Chris Lattner

2005-09-27Completely rewrite 'correct' eh support. This changes how setjmp insertionChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23477 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-27Make this slightly more efficient by pushing actual type information downChris Lattner

2005-09-27Split SimpleConstantVal up into its components, so each Constant subclass ↵Chris Lattner
getsa different enum value. This allows 'classof' for these to be really simple,not needing to call getType() anymore. 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23467 91177308-0d34-0410-b5e6-96231b3b80d8
