* Mark shortening NaN conversions as Inexact. PR 2856.Dale Johannesen2008-10-061-6/+9
| | | | | | Improve description of unsupported formats. llvm-svn: 57185
* It is possible that all functions in one module are not being Devang Patel2008-10-061-5/+2
| | | | | | optimized for size. Set OptForSize for each function separately. llvm-svn: 57182
* Don't dereference the end() iterator. Thanks toDan Gohman2008-10-061-1/+1

* Allow scalarrepl to treat an all-zero GEP just as bitcast.Matthijs Kooijman2008-10-061-14/+28
| | | | | | | This includes not marking a GEP involving a vector as unsafe, but only when it has all zero indices. This allows scalarrepl to work in a few more cases. llvm-svn: 57177

| | | | | | Patch by Robert G. Jakabosky! llvm-svn: 57110
* Fix weird think-o and unbreak build on all gcc-3.4.x-based platforms (e.g. ↵Anton Korobeynikov2008-10-053-98/+91

* rewrite bswap matching to be more general, allowing arbitraryChris Lattner2008-10-051-77/+121
| | | | | | | | shifting and masking inside a bswap expr. This allows it to handle the cases from PR2842, which involve the intermediate 'or' expressions being shifted, not just the input value. llvm-svn: 57095
* fix a bug where the bswap matcher could match a case involvingChris Lattner2008-10-051-1/+4
| | | | | | ashr. It should only apply to lshr. llvm-svn: 57089
* wrap some long lines and expand i32 mul's to libcalls, inspired by aChris Lattner2008-10-041-4/+12
| | | | | | patch by Mikael Lepisto! llvm-svn: 57077
* CMake: Reflected changes on source file structure. New plugin supportOscar Fuentes2008-10-041-0/+2
| | | | | | for llvmc2 incomplete. llvm-svn: 57076
* Ignore loads from and stores to local memory (i.e. allocas)Duncan Sands2008-10-041-9/+26
| | | | | | | | when deciding whether to mark a function readnone/readonly. Since the pass is currently run before SROA, this may be quite helpful. Requested by Chris on IRC. llvm-svn: 57050
* Allow the construction of SCEVs with SCEVCouldNotCompute operands, byNick Lewycky2008-10-041-0/+67
| | | | | | implementing folding. Fixes PR2857. llvm-svn: 57049
* Revert r56675 - it breaks unwinding runtime everywhere.Anton Korobeynikov2008-10-041-18/+8

* Add implementations for sys::Memory::setWritable and ↵Argyrios Kyrtzidis2008-10-041-0/+8
| | | | | | sys::Memory::setExecutable on Win32 platform. llvm-svn: 57047
* Fix compilation error on MSVC.Argyrios Kyrtzidis2008-10-041-1/+1
| | | | llvm-svn: 57046
* Fix fast-isel's handling of atomic instructions. They mayDan Gohman2008-10-041-1/+4
| | | | | | | | expand to multiple basic blocks, in which case fast-isel needs to informed of which block to use as it resumes inserting instructions. llvm-svn: 57040
* Fix a bug in the local allocator's liveness computation where itDan Gohman2008-10-041-3/+5
| | | | | | | | was setting kill flags on tied uses in two-address instructions. The kill flags were causing the allocator to think it could allocate the use and its tied def in different registers. llvm-svn: 57039
* Make atomic Swap work, 64-bit on x86-32.Dale Johannesen2008-10-034-11/+33
| | | | | | Make it all work in non-pic mode. llvm-svn: 57034
* Clean up some multiple-return-value code that is no longerDan Gohman2008-10-031-5/+1

* Fix function attribute verification check.Devang Patel2008-10-031-6/+5
| | | | | | Thanks Duncan! llvm-svn: 57029
* Pass MemOperand through for 64-bit atomics on 32-bit,Dale Johannesen2008-10-034-9/+27
| | | | | | | incidentally making the case where the memop is a pointer deref work. Fix cmp-and-swap regression. llvm-svn: 57027
* Nick Lewycky's patch.Devang Patel2008-10-031-1/+1
| | | | | | While hosting instruction check PHI node. llvm-svn: 57025

| | | | llvm-svn: 57017
* Avoid creating two TargetLowering objects for each target.Dan Gohman2008-10-0311-33/+22
| | | | | | | | | | | | Instead, just create one, and make sure everything that needs it can access it. Previously most of the SelectionDAGISel subclasses all had their own TargetLowering object, which was redundant with the TargetLowering object in the TargetMachine subclasses, except on Sparc, where SparcTargetMachine didn't have a TargetLowering object. Change Sparc to work more like the other targets here. llvm-svn: 57016
* Remove an unused field.Dan Gohman2008-10-031-6/+1

* On Darwin ARM, memory needs special handling to do JIT. This patch expandsJim Grosbach2008-10-034-13/+51
| | | | | | | this handling to work properly for modifying stub functions, relocations back to entry points after JIT compilation, etc.. llvm-svn: 57013
* Indexing off by one resulted in errant encoding of source register forJim Grosbach2008-10-031-1/+1
| | | | | | reg->reg moves. llvm-svn: 57011
* NeedStub/DoesntNeedStub logic was reversed, leading to not using a stubJim Grosbach2008-10-031-4/+4
| | | | | | for global relocations that do need them (libc calls, for example). llvm-svn: 57010

* The result of getSetCCResultType (eg: i32) may be largerDuncan Sands2008-10-031-4/+8
| | | | | | | | | than the type an i1 is promoted to (eg: i8). Account for this. Noticed by Tilmann Scheller on CellSPU; he will hopefully take care of fixing this in LegalizeDAG and adding a testcase! llvm-svn: 56997
* Teach internalize to preserve the callgraph.Duncan Sands2008-10-032-0/+20
| | | | | | Why? Because it was there! llvm-svn: 56996

* Implement fast-isel support for zero-extending from i1.Dan Gohman2008-10-031-1/+12
| | | | | | | It turns out that this is a fairly common operation, and it's easy enough to handle. llvm-svn: 56990
* Fix X86FastISel to handle dynamic allocas that have avoidedDan Gohman2008-10-031-0/+10
