* Fix invalid reads by memcmp.Benjamin Kramer2012-10-031-1/+1

* Remove useless parameter "WantFile" from Driver::GetProgramPath().Simon Atanasyan2012-10-034-20/+10
| | | | | | | | | This parameter is useless because nowhere used explicitly and always gets its default value - "false". The patch reviewed by Rafael Espindola. llvm-svn: 165149

We attempted to merge loads with a different chain. When that happened, the assumption that it is safe to RAUW broke and a cycle was introduced. llvm-svn: 165148

* This patch enables general varargs support for the 64-bit PPC SVR4 ABI.Bill Schmidt2012-10-031-4/+102
| | | | | | | | | | | | | | Most of the pieces for this were already in place, but a proper EmitVAArg is needed for aggregates and complex numbers to be handled. Although the va_list for 64-bit PowerPC SVR4 consists of GPRs 3 through 10 together with the overflow portion of the parameter save area, we can treat va_list as pointing to contiguous memory for all parameters, since the back end forces the parameter GPRs to memory for varargs functions. There is no need at this time to model parameters and return values beyond what the DefaultABIInfo provides. llvm-svn: 165143

* This Patch corrects a problem whereby the optimization to use a faster dividePreston Gurd2012-10-031-5/+15
| | | | | | | | | | | | | | instruction (for Intel Atom) was not being done by Clang, because the type context used by Clang is not the default context. It fixes the problem by getting the global context types for each div/rem instruction in order to compare them against the types in the BypassTypeMap. Tests for this will be done as a separate patch to Clang. Patch by Tyler Nowicki. llvm-svn: 165126
* A DAGCombine optimization for mergeing consecutive stores to memory. The ↵Nadav Rotem2012-10-032-0/+668
| | | | | | | | | | | | | | | | | | | | | optimization is not profitable in many cases because modern processors perform multiple stores in parallel and merging stores prior to merging requires extra work. We handle two main cases: 1. Store of multiple consecutive constants: q->a = 3; q->4 = 5; In this case we store a single legal wide integer. 2. Store of multiple consecutive loads: int a = p->a; int b = p->b; q->a = a; q->b = b; In this case we load/store either ilegal vector registers or legal wide integer registers. llvm-svn: 165125

* Try to use a better set of abstractions for computing the alignmentChandler Carruth2012-10-032-20/+87
| | | | | | | | | | | | | | | | | | | | necessary during rewriting. As part of this, fix a real think-o here where we might have left off an alignment specification when the address is in fact underaligned. I haven't come up with any way to trigger this, as there is always some other factor that reduces the alignment, but it certainly might have been an observable bug in some way I can't think of. This also slightly changes the strategy for placing explicit alignments on loads and stores to only do so when the alignment does not match that required by the ABI. This causes a few redundant alignments to go away from test cases. I've also added a couple of tests that really push on the alignment that we end up with on loads and stores. More to come here as I try to fix an underlying bug I have conjectured and produced test cases for, although it's not clear if this bug is the one currently hitting dragonegg's gcc47 bootstrap. llvm-svn: 165100

| | | | | | | | | | | | | * nullptr used to be mapped to ERROR, now mapped to nullptr * integral was missing * expressions now have their own error message, so they won't reach this. Map them to ERROR. Note that clang usually crashes before emitting this diagnostic anyway (see PR13984), so this change alone doesn't have an observable effect. It makes the code more correct though. llvm-svn: 165095
