2011-02-23Add llvm.xcore.waitevent intrinsic. The effect of this intrinsic is to enableRichard Osborne
events on the thread and wait until a resource is ready to event. The vector of the resource that is ready is returned. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126320 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-23Omit private_extern declarations of extern symbols; followup toStuart Hastings
r124468. Patch by Rafael Avila de Espindola! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126297 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-22Fix C++0x incompatibility. The signature of std::make_pair<> changes from:Nick Lewycky
template <class T1, class T2> pair<T1,T2> make_pair(const T1&, const T2&); to template <class T1, class T2> pair<V1, V2> make_pair(T1&&, T2&&); so explicitly specifying the template arguments to make_pair<> is going to break when C++0x rolls through. Replace them with equivalent std::pair<>. Patch by James Dennett! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126256 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-22Follow LLVM coding style. Devang Patel
clang uses DBuilder, so it requries corresponding change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126231 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-22MachineConstantPoolValues are not uniqued, so they need to be freed if theyCameron Zwarich
share entries. Add a DenseSet to MachineConstantPool for the MachineCPVs that it owns. This will hopefully fix the MC/ARM/elf-reloc-01.ll failure on the leaks bots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126218 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-22Merge information about the number of zero, one, and sign bits of live-out ↵Cameron Zwarich
registers at phis. This enables us to eliminate a lot of pointless zexts during the DAGCombine phase. This fixes <rdar://problem/8760114>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126170 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-21Revert r124611 - "Keep track of incoming argument's location while emitting ↵Devang Patel
LiveIns." In other words, do not keep track of argument's location. The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body. This requires some coordination with debugger to get this working. - The debugger needs to be aware of prolog_end attribute attached with line table entries. - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126155 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-21Add XCore intrinsics for various instructions on ports.Richard Osborne
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126132 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-21If the phi node was used by an unreachable instruction that ends up usingDuncan Sands
itself without going via a phi node then we could return false here in spite of making a change. Also, tweak the comment because this method can (and always could) return true without deleting the original phi node. For example, if the phi node was used by a read-only invoke instruction which is used by another phi node phi2 which is only used by and only uses the invoke, then phi2 would be deleted but not the invoke instruction and not the original phi node. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126129 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-18Do not lose debug info of an inlined function argument even if the argument ↵Devang Patel
is only used through GEPs. This time with a fix that avoids using invalidated DenseMap iterator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125984 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-18Now that -loop-idiom uses TargetLibraryInfo properly, it doesn'tChris Lattner
need to be pulled out of the pass manager when the user specifies -fno-builtin. It can intelligently determine which libcalls to optimize based on what is enabled in TargetLibraryInfo. This allows -fno-builtin-foo to work someday. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125981 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125972 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-18Add FixedLenDecoderEmitter, the skeleton of a new disassembler emitter for ↵Owen Anderson
fixed-length instruction encodings. A major part of its (eventual) goal is to support a much cleaner separation between disassembly callbacks provided by the target and the disassembler emitter itself, i.e. not requiring hardcoding of knowledge in tblgen like the existing disassembly emitters do. The hope is that some day this will allow us to replace the existing non-Thumb ARM disassembler and remove some of the hacks the old one introduced to tblgen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125966 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-18introduce a new TargetLibraryInfo pass, which transformations can use toChris Lattner
query about available library functions. For now this just has memset_pattern16, which exists on darwin, but it can be extended for a bunch of other things in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125965 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-14Move more fragments of spill weight calculation into CalcSpillWeights.hJakob Stoklund Olesen
Simplify the spill weight calculation a bit by bypassing getApproximateInstructionCount() and using LiveInterval::getSize() directly. This changes the computed spill weights, but only by a constant factor in each function. It should not affect how spill weights compare against each other, and so it shouldn't affect code generation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125530 91177308-0d34-0410-b5e6-96231b3b80d8
