* [ELF] Ignore R_*_NONE relocs when relocating non-alloc sectionsPetr Hosek2017-02-236-7/+31
| | | | | | | | | We shouldn't report an error for R_*_NONE relocs since we're emitting them when writing relocations to discarded sections. Differential Revision: https://reviews.llvm.org/D30279 llvm-svn: 295936
* [CodeGen] Don't reemit expressions for pass_object_size params.George Burgess IV2017-02-234-28/+78
| | | | | | | | | | | | | | This fixes an assertion failure in cases where we had expression statements that declared variables nested inside of pass_object_size args. Since we were emitting the same ExprStmt twice (once for the arg, once for the @llvm.objectsize call), we were getting issues with redefining locals. This also means that we can be more lax about when we emit @llvm.objectsize for pass_object_size args: since we're reusing the arg's value itself, we don't have to care so much about side-effects. llvm-svn: 295935
* [c-index-test] For the 'core' invocation, avoid running it under a new thread.Argyrios Kyrtzidis2017-02-231-3/+3

* LoadStoreVectorizer: Split even sized illegal chains properlyMatt Arsenault2017-02-235-9/+227
| | | | | | | | | | | | | | | | | | | | Implement isLegalToVectorizeLoadChain for AMDGPU to avoid producing private address spaces accesses that will need to be split up later. This was doing the wrong thing in the case where the queried chain was an even number of elements. A possible <4 x i32> store was being split into store <2 x i32> store i32 store i32 rather than store <2 x i32> store <2 x i32> when legal. llvm-svn: 295933

* [ODRHash] Handle types in ODR hashing.Richard Trieu2017-02-232-2/+76
| | | | | | | | | | Fields will now have their types added to the hash, allowing for detection of mismatched field types. This detection allows the existing ODR checking to produce the correct message. Differential Revision: https://reviews.llvm.org/D21675 llvm-svn: 295931
* [X86][IR] In AutoUpgrade, check explicitly for xop.vpcmov and xop.vpcmov.256 ↵Craig Topper2017-02-231-1/+2
| | | | | | | | | | instead of anything starting with xop.vpcmov There were some older intrinsics that only existed for less than a month in 2012 that still exist in some out of tree test files that start with this string, but aren't able to be handled by the current upgrade code and fire an assert. Now we'll go back to treating them as not intrinsics at all and just passing them through to output. Fixes PR32041, sort of. llvm-svn: 295930

* Convert InputSectionBase to a class.Rafael Espindola2017-02-2328-366/+385

* Changed builld-llvm.py to use .json filesSean Callanan2017-02-235-31/+111
| | | | | | | | | | | | | | | | | | | | | | | LLDB has many branches in a variety of repositories. The build-script.py file is subtly different for each set. This is unnecessary and causes merge headaches. This patch makes build-llvm.py consult a directory full of .json files, each one of which matches a particular branch using a regular expression. This update to the patch introduces a FALLBACK file whose contents take precedence if the current branch could not be identified. If the current branch could be identified, FALLBACK is updated, allowing the user to e.g. cut branches off of known branches and still have the automatic checkout mechanism work. It also documents all of this. Differential revision: https://reviews.llvm.org/D30275 llvm-svn: 295922
* Fix tracking of whether the previous template instantiation stack matches ↵Richard Smith2017-02-237-52/+17
| | | | | | | | | | | | | | | | | the current one. Rather than attempting to compare whether the previous and current top of context stack are "equal" (which fails for a number of reasons, such as the context stack entries containing pointers to objects on the stack, or reaching the same "top of stack" entry through two different paths), track the depth of context stack at which we last emitted a note and invalidate it when we pop the context stack to less than that depth. This causes us to emit some missing "in instantiation of" notes and to stop emitting redundant "in instantiation of" stacks matching the previous stack in rare cases. llvm-svn: 295921

* AMDGPU: Fold FP clamp as modifier bitMatt Arsenault2017-02-229-15/+420
| | | | | | | | | | | The manual is unclear on the details of this. It's not clear to me if denormals are not allowed with clamp, or if that is only omod. Not allowing denorms for fp16 or fp64 isn't useful so I also question if that is really a restriction. Same with whether this is valid without IEEE mode enabled. llvm-svn: 295905

* [InstCombine] don't try SimplifyDemandedInstructionBits from add/sub because ↵Sanjay Patel2017-02-221-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | it's slow and unlikely to succeed Notably, no regression tests change when we remove these calls, and these are expensive calls. The motivation comes from the general acknowledgement that the compiler is getting slower: http://lists.llvm.org/pipermail/llvm-dev/2017-January/109188.html http://lists.llvm.org/pipermail/llvm-dev/2016-December/108279.html And specifically the test case attached to PR32037: https://bugs.llvm.org//show_bug.cgi?id=32037 Profiling the middle-end (opt) part of the compile: $ ./opt -O2 row_common.bc -o /dev/null ...visitAdd and visitSub are near the top of the instcombine list, and the calls to SimplifyDemandedInstructionBits() are high within each of those. Those calls account for 1%+ of the opt time in either debug or release profiles. And that's the rough win I see from this patch when testing opt built release from r295864 on an iMac with Haswell 4GHz (model 4790K). It seems unlikely that we'd be able to eliminate add/sub or change their operands given that add/sub normally affect all bits, and the PR32037 example shows no IR difference after this change using -O2. Also worth noting - the code comment in visitAdd: // This handles stuff like (X & 254)+1 -> (X&254)|1 ...isn't true. That transform is handled later with a call to haveNoCommonBitsSet().
