| * Cleanup relocation sorting for ELF.Rafael Espindola2013-05-15
| | | | | | | | | | | | | | | | | | | | We want the order to be deterministic on all platforms. NAKAMURA Takumi fixed that in r181864. This patch is just two small cleanups: * Move the function to the cpp file. It is only passed to array_pod_sort. * Remove the ppc implementation which is now redundant git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181910 91177308-0d34-0410-b5e6-96231b3b80d8

| * Remove MCELFObjectTargetWriter::adjustFixupOffset hackUlrich Weigand2013-05-15
| | | | | | | | | | | | | | | | | | | | Now that PowerPC no longer uses adjustFixupOffset, and no other back-end (ever?) did, we can remove the infrastructure itself (incidentally addressing a FIXME to that effect). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181895 91177308-0d34-0410-b5e6-96231b3b80d8
| * Use only explicit bool conversion operatorsDavid Blaikie2013-05-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BitVector/SmallBitVector::reference::operator bool remain implicit since they model more exactly a bool, rather than something else that can be boolean tested. The most common (non-buggy) case are where such objects are used as return expressions in bool-returning functions or as boolean function arguments. In those cases I've used (& added if necessary) a named function to provide the equivalent (or sometimes negative, depending on convenient wording) test. One behavior change (YAMLParser) was made, though no test case is included as I'm not sure how to reach that code path. Essentially any comparison of llvm::yaml::document_iterators would be invalid if neither iterator was at the end. This helped uncover a couple of bugs in Clang - test cases provided for those in a separate commit along with similar changes to `operator bool` instances in Clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181868 91177308-0d34-0410-b5e6-96231b3b80d8

| * SectionMemoryManager shouldn't be a JITMemoryManager. Previously, the Filip Pizlo2013-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | EngineBuilder interface required a JITMemoryManager even if it was being used to construct an MCJIT. But the MCJIT actually wants a RTDyldMemoryManager. Consequently, the SectionMemoryManager, which is meant for MCJIT, derived from the JITMemoryManager and then stubbed out a bunch of JITMemoryManager methods that weren't relevant to the MCJIT. This patch fixes the situation: it teaches the EngineBuilder that RTDyldMemoryManager is a supertype of JITMemoryManager, and that it's appropriate to pass a RTDyldMemoryManager instead of a JITMemoryManager if we're using the MCJIT. This allows us to remove the stub methods from SectionMemoryManager, and make SectionMemoryManager a direct subtype of RTDyldMemoryManager. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181820 91177308-0d34-0410-b5e6-96231b3b80d8
| * Remove the MachineMove class.Rafael Espindola2013-05-13
| | | | | | | | | | | | | | | | | | | | | | | | It was just a less powerful and more confusing version of MCCFIInstruction. A side effect is that, since MCCFIInstruction uses dwarf register numbers, calls to getDwarfRegNum are pushed out, which should allow further simplifications. I left the MachineModuleInfo::addFrameMove interface unchanged since this patch was already fairly big. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181680 91177308-0d34-0410-b5e6-96231b3b80d8

| * Rewrite assert to avoid warning when the record element type is byte-sized.Jordan Rose2013-05-09
| | | | | | | | | | | | | | | | | | | | BitstreamWriter asserts that when blob data is written from the record element vector, each element fits in a byte. However, if the record elements are specified as a SmallVector of 'char', this causes a warning from -Wtautological-constant-out-of-range-compare.

| * [PowerPC] Add some missing PPC64 relocsUlrich Weigand2013-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All R_PPC_... relocs should also be present (using the same number) under the corresponding R_PPC64_... name. The latter were missing for a couple of cases, which this patch adds. This is not a big problem when emitting the reloc, because we can just use the R_PPC_... define instead. But it is a problem when *dumping* relocations e.g. using llvm-readobj, because this will expect only R_PPC64_... values when inspecting a ppc64 ELF file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181451 91177308-0d34-0410-b5e6-96231b3b80d8

| * PatternMatch: Matcher for (un)ordered floating point min/maxArnold Schwaighofer2013-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for matching 'ordered' and 'unordered' floating point min/max constructs. In LLVM we can express min/max functions as a combination of compare and select. We have support for matching such constructs for integers but not for floating point. In floating point math there is no total order because of the presence of 'NaN'. Therefore, we have to be careful to preserve the original fcmp semantics when interpreting floating point compare select combinations as a minimum or maximum function. The resulting 'ordered/unordered' floating point maximum function has to select the same value as the select/fcmp combination it is based on. ordered_max(x,y) = max(x,y) iff x and y are not NaN, y otherwise unordered_max(x,y) = max(x,y) iff x and y are not NaN, x otherwise ordered_min(x,y) = min(x,y) iff x and y are not NaN, y otherwise unordered_min(x,y) = min(x,y) iff x and y are not NaN, x otherwise This matches the behavior of the underlying select(fcmp(olt/ult/.., L, R), L, R) construct. Any code using this predicate has to preserve this semantics. A follow-up patch will use this to implement floating point min/max reductions in the vectorizer. radar://13723044 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181143 91177308-0d34-0410-b5e6-96231b3b80d8
