* [MSVC Compatibility] Classify ext_ms_cast_fn_obj as DefaultErrorDavid Majnemer2015-08-112-2/+2
| | | | | | | | This non-conforming extension was introduced to make it possible for us to correctly compile <atomic> in VS 2013 and 2015. Let's limit its impact to system headers to encourage portable code. llvm-svn: 244650
* SelectionDAG: Prefer to combine multiplication with less uses for fmaJingyue Wu2015-08-112-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: For example: s6 = s0*s5; s2 = s6*s6 + s6; ... s4 = s6*s3; We notice that it is possible for s2 is folded to fma (s0, s5, fmul (s6 s6)). This only happens when Aggressive is true, otherwise hasOneUse() check already prevents from folding the multiplication with more uses.

* Revert "[cmake] Add helper for finding potentially external projects"Reid Kleckner2015-08-111-17/+0
| | | | | | | | | | This reverts commit r244633. We aren't going to be able to use it because the compiler-rt build can be built standalone without an LLVM source dir *or* an installed copy of LLVM. llvm-svn: 244648

* [LowerSwitch] Fix a bug when LowerSwitch deletes the default blockChen Li2015-08-112-5/+37
| | | | | | | | | | | | Summary: LowerSwitch crashed with the attached test case after deleting the default block. This happened because the current implementation of deleting dead blocks is wrong. After the default block being deleted, it contains no instruction or terminator, and it should no be traversed anymore. However, since the iterator is advanced before processSwitchInst() function is executed, the block advanced to could be deleted inside processSwitchInst(). The deleted block would then be visited next and crash dyn_cast<SwitchInst>(Cur->getTerminator()) because Cur->getTerminator() returns a nullptr. This patch fixes this problem by recording dead default blocks into a list, and delete them after all processSwitchInst() has been done. It still possible to visit dead default blocks and waste time process them. But it is a compile time issue, and I plan to have another patch to add support to skip dead blocks.

* [Windows] Use llvm-symbolizer before using dbghelpReid Kleckner2015-08-1112-427/+601
| | | | | | | | | | | | | | | | | | | | | | | Summary: llvm-symbolizer understands both PDBs and DWARF, so it's a better bet if it's available. It prints out the function parameter types and column numbers, so I needed to churn the expected test output a bit. This makes most of the llvm-symbolizer subprocessing code target-independent. Pipes on all platforms use fd_t, and we can use the portable ReadFromFile / WriteToFile wrappers in symbolizer_sanitizer.cc. Only the pipe creation and process spawning is Windows-specific. Please check that the libcdep layering is still correct. I don't know how to reproduce the build configuration that relies on that.

* [GlobalMerge] Use private linkage for MergedGlobals variablesJohn Brawn2015-08-1111-91/+62
| | | | | | | | | | | | | | | Other objects can never reference the MergedGlobals symbol so external linkage is never needed. Using private instead of internal linkage means the object is more similar to what it looks like when global merging is not enabled, with the only difference being that the merged variables are addressed indirectly relative to the start of the section they are in. Also add aliases for merged variables with internal linkage, as this also makes the object be more like what it is when they are not merged.

* Fix InstCombine test: invalid CHECK line slipped in r231270Mehdi Amini2015-08-111-1/+2
| | | | | | | | | | | | | | I incorrectly wrote CHECK-NEXT with followin with ':', the check was ignored by FileCheck. The non-inbound GEP is folded here because the DataLayout is no longer optional, the fold was originally guarded with a comment that said: We need TD information to know the pointer size unless this is inbounds. Now we always have "TD information" and perform the fold. Thanks Jonathan Roelofs for noticing. From: Mehdi Amini <mehdi.amini@apple.com> llvm-svn: 244613

* [RegionInfo] Verify getRegionForMichael Kruse2015-08-112-0/+27
| | | | | | | | | | | | | | | Summary: Check the contents of BBtoRegion during analysis verification. It only takes place if -verify-region-info is passed or LLVM is compiled with XDEBUG. RegionBase<Tr>::verifyRegion() also checks the RegionInfoBase<Tr>::VerifyRegionInfo flag, which is redundant, but verifyRegion() is public API and might be invoked from other sites. In order to avoid behavioral change, this check is not removed. In any case, no region will be verified unless VerifyRegionInfo is set.

* Assign regions to all BBs from CodeGenerationMichael Kruse2015-08-111-0/+13
| | | | | | | | | | In order to have a valid region analysis, we assign all newly created blocks to the parent of the scop's region. This is correct for any pre-existing regions (including the scop's region and its parent), but does not discover any region inside the generated code. For Polly this is not necessary because we do not want to re-run Polly on its own generated code anyway.
