* [IndVars] Change the order to compute WidenAddRec in widenIVUse.Wei Mi2016-11-153-4/+65
| | | | | | | | | | | | | | | | When both WidenIV::getWideRecurrence and WidenIV::getExtendedOperandRecurrence return non-null but different WideAddRec, if getWideRecurrence is called before getExtendedOperandRecurrence, we won't bother to call getExtendedOperandRecurrence again. But As we know it is possible that after SCEV folding, we cannot prove the legality using the SCEVAddRecExpr returned by getWideRecurrence. Meanwhile if getExtendedOperandRecurrence returns non-null WideAddRec, we know for sure that it is legal to do widening for current instruction. So it is better to put getExtendedOperandRecurrence before getWideRecurrence, which will increase the chance of successful widening.

| | | | | | | | | With a max_load_factor of 1.0, the only guarantee is that bucket_count() >= size(). (Note: setting max_load_factor without rehashing isn't supposed to affect this, because setting max_load_factor is currently specified to be constant time.) llvm-svn: 286982

* [X86][SSE] Improve SINT_TO_FP of boolean vector results (signum)Simon Pilgrim2016-11-153-109/+19
| | | | | | | | | | | | This patch helps avoids poor legalization of boolean vector results (e.g. 8f32 -> 8i1 -> 8i16) that feed into SINT_TO_FP by inserting an early SIGN_EXTEND and so help improve the truncation logic. This is not necessary for AVX512 targets where boolean vectors are legal - AVX512 manages to lower ( sint_to_fp vXi1 ) into some form of ( select mask, 1.0f , 0.0f ) in most cases.

Things can still break if we use different ARM target machines or if we have functions with different 'target-cpu' or 'target-features', we should fix that too in the future. llvm-svn: 286974

* [PowerPC] Implement BE VSX load/store builtins - clang portion.Tony Jiang2016-11-156-3/+311
| | | | | | | | | | | | This patch implements all the overloads for vec_xl_be and vec_xst_be. On BE, they behaves exactly the same with vec_xl and vec_xst, therefore they are simply implemented by defining a matching macro. On LE, they are implemented by defining new builtins and intrinsics. For int/float/long long/double, it is just a load (lxvw4x/lxvd2x) or store(stxvw4x/stxvd2x). For char/char/short, we also need some extra shuffling before or after call the builtins to get the desired BE order. For int128, simply call vec_xl or vec_xst. llvm-svn: 286971
* [LoopVectorizer] When estimating reg usage, unused insts may "end" another useRobert Lougher2016-11-153-4/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | The register usage algorithm incorrectly treats instructions whose value is not used within the loop (e.g. those that do not produce a value). The algorithm first calculates the usages within the loop. It iterates over the instructions in order, and records at which instruction index each use ends (in fact, they're actually recorded against the next index, as this is when we want to delete them from the open intervals). The algorithm then iterates over the instructions again, adding each instruction in turn to a list of open intervals. Instructions are then removed from the list of open intervals when they occur in the list of uses ended at the current index. The problem is, instructions which are not used in the loop are skipped. However, although they aren't used, the last use of a value may have been recorded against that instruction index. In this case, the use is not deleted from the open intervals, which may then bump up the estimated register usage. This patch fixes the issue by simply moving the "is used" check after the loop which erases the uses at the current index. Differential Revision: https://reviews.llvm.org/D26554 llvm-svn: 286969

* [test] Correctly include build llvm_shlib_dir in stand-alone buildsMichal Gorny2016-11-151-1/+6
| | | | | | | | | | | | | | | | Add the build llvm_shlib_dir into LD_LIBRARY_PATH before the directory specified as llvm_libs_dir, in order to fix stand-alone builds attempting to use installed clang libraries. In case of stand-alone builds llvm_libs_dir specifies the location of installed LLVM libraries which can also contain an older version (previous build) of clang libraries. Therefore, ensure to specify llvm_shlib_dir (which is always the build tree path) before the potentially-system llvm_libs_dir. Differential Revision: https://reviews.llvm.org/D26115 llvm-svn: 286952
* Introduce TLI predicative for base-relative Jump Tables.Joerg Sonnenberger2016-11-154-38/+10
| | | | | | | | | | | For 64bit ABIs it is common practice to use relative Jump Tables with potentially different relocation bases. As the logic for the jump table itself doesn't depend on the relocation base, make it easier for targets to use the generic logic. Start by dropping the now redundant MIPS logic.

Summary: This change is preparation for a change that will allow targets to verify that the instructions they emit meet the predicates they specify. This is useful to ensure that C++ legalization/lowering/instruction-selection doesn't incorrectly select code for a different subtarget than intended. Such cases are not caught by the integrated assembler when emitting instructions directly to an object file.
