* [Cloning] Clone every Function's Debug InfoKeno Fischer2016-02-132-2/+3
| | | | | | | | | | | | | | | | | | | | | | | Summary: Export the CloneDebugInfoMetadata utility, which clones all debug info associated with a function into the first module. Also use this function in CloneModule on each function we clone (the CloneFunction entrypoint already does this). Without this, cloning a module will lead to DI quality regressions, especially since r252219 reversed the Function <-> DISubprogram edge (before we could get lucky and have this edge preserved if the DISubprogram itself was, e.g. due to location metadata). This was verified to fix missing debug information in julia and a unittest to verify the new behavior is included. Patch by Yichao Yu! Thanks!

* Add AMDGPU related triple vendors/OSesMatt Arsenault2016-02-131-0/+6

* Don't combine fp_round (fp_round x) if f80 to f16 is generatedPirama Arumuga Nainar2016-02-131-0/+11
| | | | | | | | | | | | | | | | | | | | Summary: This patch skips DAG combine of fp_round (fp_round x) if it results in an fp_round from f80 to f16. fp_round from f80 to f16 always generates an expensive (and as yet, unimplemented) libcall to __truncxfhf2. This prevents selection of native f16 conversion instructions from f32 or f64. Moreover, the first (value-preserving) fp_round from f80 to either f32 or f64 may become a NOP in platforms like x86.

* [Hexagon] Optimize stack slot spillsKrzysztof Parzyszek2016-02-125-3/+1089
| | | | | | | | | | | | | | Replace spills to memory with spills to registers, if possible. This applies mostly to predicate registers (both scalar and vector), since they are very limited in number. A spill of a predicate register may happen even if there is a general-purpose register available. In cases like this the stack spill/reload may be eliminated completely. This optimization will consider all stack objects, regardless of where they came from and try to match the live range of the stack slot with a dead range of a register from an appropriate register class. llvm-svn: 260758

* [GVN] Common code for local and non-local load availability [NFCI]Philip Reames2016-02-121-248/+148
| | | | | | | | | | | | The attached patch removes all of the block local code for performing X-load forwarding by reusing the code used in the non-local case. The motivation here is to remove duplication and in the process increase our test coverage of some fairly tricky code. I have some upcoming changes I'll be proposing in this area and wanted to have the code cleaned up a bit first. Note: The review for this mostly happened in email which didn't make it to phabricator on the 258882 commit thread. Differential Revision: http://reviews.llvm.org/D16608 llvm-svn: 260711
* [LIR] Partially revert r252926(NFC), which introduced a very subtle change.Chad Rosier2016-02-121-8/+8
| | | | | | | | | | | | | In short, before r252926 we were comparing an unsigned (StoreSize) against an a APInt (Stride), which is fine and well. After we were zero extending the Stride and then converting to an unsigned, which is not the same thing. Obviously, Stides can also be negative. This commit just restores the original behavior. AFAICT, it's not possible to write a test case to expose the issue because the code already has checks to make sure the StoreSize can't overflow an unsigned (which prevents the Stride from overflowing an unsigned as well). llvm-svn: 260706
* [LVI] Exploit nsw/nuw when computing constant rangesPhilip Reames2016-02-121-0/+21
| | | | | | | | | | As the title says. Modelled after similar code in SCEV. This is useful when analysing induction variables in loops which have been canonicalized by other passes. I wrote the tests as non-loops specifically to avoid the generality introduced in http://reviews.llvm.org/D17174. While that can handle many induction variables without *needing* to exploit nsw, there's no reason not to use it if we've already proven it.

* [InstCombine] Don't aggressively replace xor with icmpDavid Majnemer2016-02-121-17/+20
| | | | | | | | | | | | | | | | | | For some cases, InstCombine replaces the sequence of xor/sub instruction followed by cmp instruction into a single cmp instruction. However, this replacement may result suboptimal result especially when the xor/sub has more than one use, as discussed in bug 26465 (https://llvm.org/bugs/show_bug.cgi?id=26465). This patch make the replacement happen only when xor/sub has only one use. Differential Revision: http://reviews.llvm.org/D16915 Patch by Taewook Oh! llvm-svn: 260695

| | | | | | | | | | | | | | | Summary: It is possible that the loop condition can be a boolean constant (infinite loop, for example). So we sould handle constant condition in annotating a loop. This patch adds this functionality to support annotating constant condition.

* [Hexagon] Eliminate pseudo instructions for circ/brev loads and storesKrzysztof Parzyszek2016-02-125-461/+192
| | | | | | | | | We can generate the actual instructions from the intrinsics without the need for pseudo-instructions. Also, since the intrinsics have a side- effect in a form of a store, attempt to optimize away loads from the store location. llvm-svn: 260690
* [AArch64] Reduce number of callee-save save/restores.Geoff Berry2016-02-121-126/+160
| | | | | | | | | | | | | | | | | | | | | Summary: Before this change, callee-save registers would be rounded up to even pairs of GPRs and FPRs. This change eliminates these extra padding load/stores, though it does keep the stack allocation the same size unless both the GPR and FPR sets have an odd size, in which case one full pair stack slot (16 bytes) is saved. This optimization cannot currently be done for MachO targets since they rely on a fast-path .debug_frame equivalent that can only encode callee-save registers as pairs.
