| | | | | | | With leaf functions, this makes nonsensical decisions based on the uniformity of the arguments. llvm-svn: 293525

* SDAG: Update ChainNodesMatched during UpdateChains if a node is replacedJustin Bogner2017-01-303-2/+51
| | | | | | | | | | | Previously, we would hit UB (or the ISD::DELETED_NODE assert) if we happened to replace a node during UpdateChains, because it would be left in the list we were iterating over. This nulls out the pointer when that happens so that we can avoid the issue. Fixes llvm.org/PR31710 llvm-svn: 293522

| | | | | | | | | To simplify/clarify memory ownership, make leaks (as one was found/fixed recently) harder to write, etc. (also, while I was there - removed a duplicate lookup in a container) llvm-svn: 293506

* DAG: Constant fold fp16_to_fp/fp16_to_fpMatt Arsenault2017-01-3014-163/+142
| | | | | | | This fixes emitting conversions of constants on targets without legal f16 that need to use these for legalization. llvm-svn: 293499
* [InstCombine] fixed to propagate 'exact' on lshrSanjay Patel2017-01-302-2/+2
| | | | | | | | | | | | | | | | | The original shift is bigger, so this may qualify as 'obvious', but here's an attempt at an Alive-based proof: Name: exact Pre: (C1 u< C2) %a = shl i8 %x, C1 %b = lshr exact i8 %a, C2 => %c = lshr exact i8 %x, C2 - C1 %b = and i8 %c, ((1 << width(C1)) - 1) u>> C2 Optimization is correct! llvm-svn: 293498

* Bring back r293480. It is safe now.Rafael Espindola2017-01-301-10/+10
| | | | | | | | | | | | | | | Original message: Fix the values of two xcore ELF flags. The values in llvm grew from a pre-MC day when they would not show up in .o files and are outside of the SHF_MASKPROC. Fortunately the MC output is not currently used as xcore has its own assemble and that assembler uses valid values. This updates llvm to use the same values as the xmos assembler. llvm-svn: 293486
* Only print architecture dependent flags for that architecture.Rafael Espindola2017-01-309-15/+27
| | | | | | | | | | Different architectures can have different meaning for flags in the SHF_MASKPROC mask, so we should always check what the architecture use before checking the flag. NFC for now, but will allow fixing the value of an xmos flag. llvm-svn: 293484
* TableGen: Fix infinite recursion in RegisterBankEmitterTom Stellard2017-01-302-3/+26
| | | | | | | | | | | | | | | | Summary: AMDGPU has two register classes with the same set of registers, and this was causing this tablegen backend would get stuck in infinite recursion.

* [LoopVectorize] Improve getVectorCallCost() getScalarizationOverhead() call.Jonas Paulsson2017-01-301-19/+8
| | | | | | | | | | | | | | By calling getScalarizationOverhead with the CallInst instead of the types of its arguments, we make sure that only unique call arguments are added to the scalarization cost. getScalarizationOverhead() is extended to handle calls by only passing on the actual call arguments (which is not all the operands). This also eliminates a wrapper function with the same name. review: Hal Finkel llvm-svn: 293459
