* Fix register coalescer failure to prune valueStanislav Mekhanoshin2019-05-211-2/+4
| | | | | | | | | | | | | | | | | | Register coalescer fails for the test in the patch with the assertion in JoinVals::ConflictResolution `DefMI != nullptr'. It attempts to join live intervals for two adjacent instructions and erase the copy: %2:vreg_256 = COPY %1 %3:vreg_256 = COPY killed %1 The LI needs to be adjusted to kill subrange for the erased instruction and extend the subrange of the original def. That was done for the main interval only but not for the subrange. As a result subrange had a VNI pointing to the erased slot resulting in the above failure.

* [Intrinsic] Signed Fixed Point Saturation Multiplication IntrinsicLeonard Chan2019-05-219-25/+202
| | | | | | | | | | | | | | Add an intrinsic that takes 2 signed integers with the scale of them provided as the third argument and performs fixed point multiplication on them. The result is saturated and clamped between the largest and smallest representable values of the first 2 operands. This is a part of implementing fixed point arithmetic in clang where some of the more complex operations will be implemented as intrinsics.

* [MergeICmps] Make sorting strongly stable on the rhs.Clement Courbet2019-05-211-1/+2
| | | | | | | | | | | | | | | | | | | Summary: Because the sort order was not strongly stable on the RHS, whether the chain could merge would depend on the order of the blocks in the Phi. EXPENSIVE_CHECKS would shuffle the blocks before sorting, resulting in non-deterministic merging.

* [ScheduleDAGInstrs] Compute topological ordering on demand.Florian Hahn2019-05-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In most cases, the topological ordering does not get changed in ScheduleDAGInstrs.

* [PPC64] Update LocalEntry from assigned symbolsFangrui Song2019-05-211-6/+24
| | | | | | | | | | | | | | | | | On PowerPC64 ELFv2 ABI, functions may have 2 entry points: global and local. The local entry point location of a function is stored in the st_other field of the symbol, as an offset relative to the global entry point. In order to make symbol assignments (e.g. .equ/.set) work properly with this, PPCTargetELFStreamer already copies the local entry bits from the source symbol to the destination one, on emitAssignment(). The problem is that this copy is performed only at the assignment location, where the source symbol may not yet have processed the .localentry directive, that sets the local entry. This may cause the destination symbol to end up with wrong local entry information. Other symbol info is not affected by this because, in this case, the destination symbol value is actually a symbol reference. This change keeps track of these assignments, and update all needed st_other fields when finish() is called. Patch by Leandro Lupori!

* [ARM][CGP] Skip nuw in PrepareConstantsSam Parker2019-05-211-72/+52
| | | | | | | | | | | | | | | PrepareConstants step converts add/sub with 'negative' immediates to sub/add with a 'positive' imm to make promotion more simple. nuw already states that the add shouldn't cause an unsigned wrap, so it shouldn't need any tweaking. Plus, we also don't allow a sub with a 'negative' immediate to be safe wrap, so this functionality has been removed. The PrepareConstants step now just handles the add instructions that we've determined would be safe if they wrap around zero. Differential Revision: https://reviews.llvm.org/D62057 llvm-svn: 361227

| | | | | | | | | | | | | | Unfortunately the way SIInsertSkips works is backwards, and is required for correctness. r338235 added handling of some special cases where skipping is mandatory to avoid side effects if no lanes are active. It conservatively handled asm correctly, but the same logic needs to apply to calls.

* [INLINER] allow inlining of blockaddresses if sole uses are callbrsNick Desaulniers2019-05-201-10/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: It was supposed that Ref LazyCallGraph::Edge's were being inserted by inlining, but that doesn't seem to be the case. Instead, it seems that there was no test for a blockaddress Constant in an instruction that referenced the function that contained the instruction. Ex: ``` define void @f() { %1 = alloca i8*, align 8 2: store i8* blockaddress(@f, %2), i8** %1, align 8 ret void } ``` When iterating blockaddresses, do not add the function they refer to back to the worklist if the blockaddress is referring to the contained function (as opposed to an external function). Because blockaddress has sligtly different semantics than GNU C's address of labels, there are 3 cases that can occur with blockaddress, where only 1 can happen in GNU C due to C's scoping rules: * blockaddress is within the function it refers to (possible in GNU C). * blockaddress is within a different function than the one it refers to (not possible in GNU C). * blockaddress is used in to declare a global (not possible in GNU C). The second case is tested in: ``` $ ./llvm/build/unittests/Analysis/AnalysisTests \ --gtest_filter=LazyCallGraphTest.HandleBlockAddress ``` This patch adjusts the iteration of blockaddresses in LazyCallGraph::visitReferences to not revisit the blockaddresses function in the first case. The Linux kernel contains code that's not semantically valid at -O0; specifically code passed to asm goto. It requires that asm goto be inline-able. This patch conservatively does not attempt to handle the more general case of inlining blockaddresses that have non-callbr users (pr/39560). https://bugs.llvm.org/show_bug.cgi?id=39560 https://bugs.llvm.org/show_bug.cgi?id=40722 https://github.com/ClangBuiltLinux/linux/issues/6 https://reviews.llvm.org/rL212077 Reviewers: jyknight, eli.friedman, chandlerc Reviewed By: chandlerc Subscribers: george.burgess.iv, nathanchance, mgorny, craig.topper, mengxu.gatech, void, mehdi_amini, E5ten, chandlerc, efriedma, eraman, hiraditya, haicheng, pirama, llvm-commits, srhines Tags: #llvm Differential Revision: https://reviews.llvm.org/D58260 llvm-svn: 361173

[DebugInfo] Update loop metadata for inlined loops Currently, when a loop is cloned while inlining function (A) into function (B) the loop metadata is copied and then not modified at all. The loop metadata can encode the loop's start and end DILocations. Therefore, the new inlined loop in function (B) may have loop metadata which shows start and end locations residing in function (A). This patch ensures loop metadata is updated while inlining so that the start and end DILocations are given the "inlinedAt" operand. I've also added a regression test for this. This fix is required for D60831 because that patch uses loop metadata to determine the DILocation for the branches of new loop preheaders.
