* [mips] [IAS] Add support for generating DADDu to createAddu(). NFC.Toma Tabacu2015-06-231-7/+7
| | | | | | | | | | | | | | Summary: This isn't used right now, but it will be in some upcoming changes. Reviewers: dsanders Reviewed By: dsanders Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D10568 llvm-svn: 240407
* Simplify the Mangler interface now that DataLayout is mandatory.Rafael Espindola2015-06-2319-71/+51
| | | | | | | We only need to pass in a DataLayout when mangling a raw string, not when constructing the mangler. llvm-svn: 240405
* [mips64] Emit correct addend for some PC-relative relocationsPetar Jovanovic2015-06-238-79/+76
| | | | | | | | | | | So far, LLVM has not emitted correct addend for N64 and N32 ABI. This patch fixes that. It also removes fixup from MCJIT for R_MIPS_PC16 relocation. Patch by Vladimir Radosavljevic. Differential Revision: http://reviews.llvm.org/D10565 llvm-svn: 240404

* Use MCSymbols for FastISel.Rafael Espindola2015-06-2312-41/+96
| | | | | | | | | | | The summary is that it moves the mangling earlier and replaces a few calls to .addExternalSymbol with addSym. I originally wanted to replace all the uses of addExternalSymbol with addSym, but noticed it was a lot of work and doesn't need to be done all at once. llvm-svn: 240395

* MCExpr: Avoid UB by evaluating this shift as unsignedJustin Bogner2015-06-231-1/+1
| | | | | | | | We hit undefined behaviour in some MCExpr tests when the LHS of a left shift is -1. Twos-complement semantics are completely reasonable here, so we should just do the shift in unsigned. llvm-svn: 240385

* [x86] generalize reassociation optimization in machine combiner to 2 ↵Sanjay Patel2015-06-234-173/+217
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | instructions Currently ( D10321, http://reviews.llvm.org/rL239486 ), we can use the machine combiner pass to reassociate the following sequence to reduce the critical path: A = ? op ? B = A op X C = B op Y --> A = ? op ? B = X op Y C = A op B 'op' is currently limited to x86 AVX scalar FP adds (with fast-math on), but in theory, it could be any associative math/logic op (see TODO in code comment). This patch generalizes the pattern match to ignore the instruction that defines 'A'. So instead of a sequence of 3 adds, we now only need to find 2 dependent adds and decide if it's worth reassociating them. This generalization has a compile-time cost because we can now match more instruction sequences and we rely more heavily on the machine combiner to discard sequences where reassociation doesn't improve the critical path. For example, in the new test case: A = M div N B = A add X C = B add Y We'll match 2 reassociation patterns, but this transform doesn't reduce the critical path: A = M div N B = A add Y C = B add X We need the combiner to reject that pattern but select this: A = M div N B = X add Y C = B add A Differential Revision: http://reviews.llvm.org/D10460 llvm-svn: 240361

* Code cleanup: Remove std::move() around xvalue (NFC)Logan Chien2015-06-221-1/+1
| | | | | | | | | | | Remove std::move() around xvalue so that copy elision is eligible. In case that copy elision is not appliable, the c++ standard also guarantees the move semantics on xvalue. Thus, it is not necessary to wrap Args with std::move. This also silence a warning since r240345. llvm-svn: 240355

* [Object] Search for architecures by name in ↵Frederic Riss2015-06-2211-33/+44
| | | | | | | | | | | | | | | | | | | | | | | | MachOUniversalBinary::getObjectForArch() The reason we need to search by name rather than by Triple::ArchType is to handle subarchitecture correclty. There is no different ArchType for the x86_64h architecture (it identifies itself as x86_64), or for the various ARM subarches. The only way to get to the subarch slice in an universal binary is to search by name. This issue led to hard to debug and transient symbolication failures in Asan tests (it mostly works, because the files are very similar). This also affects the Profiling infrastucture as it is the other user of that API.

* [X86] Teach load folding to accept scalar _Int users of MOVSS/MOVSD.Ahmed Bougacha2015-06-222-10/+188
| | | | | | | | | | | | | | | | | | | The _Int instructions are special, in that they operate on the full VR128 instead of FR32. The load folding then looks at MOVSS, at the user, and bails out when it sees a size mismatch. What we really know is that the rm_Int instructions don't load the higher lanes, so folding is fine. This happens for the straightforward intrinsic code, e.g.: _mm_add_ss(a, _mm_load_ss(p)); Fixes PR23349. Differential Revision: http://reviews.llvm.org/D10554 llvm-svn: 240326
