2010-08-17report_fatal_error can't use errs(), because errs() can call Chris Lattner
into report_fatal_error. Just blast the string to stderr with write(2) and hope for the best! Part of rdar://8318441 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111320 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-17Temporarily revert r110987 as it's causing some miscompares inEric Christopher
vector heavy code. I'll re-enable when we've tracked down the problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111318 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-17Tweak IVUsers' concept of "interesting" to exclude add recurrencesDan Gohman
where the step value is an induction variable from an outer loop, to avoid trouble trying to re-expand such expressions. This effectively hides such expressions from indvars and lsr, which prevents them from getting into trouble. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111317 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-17Add materialization of virtual base registers for frame indices allocated intoJim Grosbach
the local block. Resolve references to those indices to a new base register. For simplification and testing purposes, a new virtual base register is allocated for each frame index being resolved. The result is truly horrible, but correct, code that's good for exercising the new code paths. Next up is adding thumb1 support, which should be very simple. Following that will be adding base register re-use and implementing a reasonable ARM heuristic for when a virtual base register should be generated at all. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111315 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-17Don't call Predicate_* methods directly from Sparc target.Jakob Stoklund Olesen
Modernize predicates a bit. The Predicate_* methods are not used by TableGen any longer. They are only emitted for the sake of legacy code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111263 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-17Add hook to examine an instruction referencing a frame index to determineJim Grosbach
whether to allocate a virtual frame base register to resolve the frame index reference in it. Implement a simple version for ARM to aid debugging. In LocalStackSlotAllocation, scan the function for frame index references to local frame indices and ask the target whether to allocate virtual frame base registers for any it encounters. Purely infrastructural for debug output. Next step is to actually allocate base registers, then add intelligent re-use of them. rdar://8277890 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111262 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-17Move the decision logic whether it's a good idea to split a critical edge to ↵Evan Cheng
clients. Also fixed an erroneous check. An edge is only a back edge when the from and to blocks are in the same loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111256 91177308-0d34-0410-b5e6-96231b3b80d8

a Pass abstraction, since that's the level it's actually used at. Rename Pass' dumpPassStructure to dumpPass.

mapping. Have the local block track its alignment requirement, and then apply that when the block itself is allocated.
