* Rename AttributeSet to AttributeListReid Kleckner2017-03-2121-47/+49
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: This class is a list of AttributeSetNodes corresponding the function prototype of a call or function declaration. This class used to be called ParamAttrListPtr, then AttrListPtr, then AttributeSet. It is typically accessed by parameter and return value index, so "AttributeList" seems like a more intuitive name. Rename AttributeSetImpl to AttributeListImpl to follow suit. It's useful to rename this class so that we can rename AttributeSetNode to AttributeSet later. AttributeSet is the set of attributes that apply to a single function, argument, or return value.

* [ARM] [Assembler] Support negative immediates for A32, T32 and T16Sanne Wouda2017-03-217-33/+145
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: To support negative immediates for certain arithmetic instructions, the instruction is converted to the inverse instruction with a negated (or inverted) immediate. For example, "ADD r0, r1, #FFFFFFFF" cannot be encoded as an ADD instruction. However, "SUB r0, r1, #1" is equivalent. These conversions are different from instruction aliases. An alias maps several assembler instructions onto one encoding. A conversion, however, maps an *invalid* instruction--e.g. with an immediate that cannot be represented in the encoding--to a different (but equivalent) instruction. Several instructions with negative immediates were being converted already, but this was not systematically tested, nor did it cover all instructions. This patch implements all possible substitutions for ARM, Thumb1 and Thumb2 assembler and adds tests. It also adds a feature flag (-mattr=+no-neg-immediates) to turn these substitutions off. This is helpful for users who want their code to assemble to exactly what they wrote.

| | | | | | | | | | We could do better by splitting any oversized type into whatever vector size the target supports, but I left that for future work if it ever comes up. The motivating case is memcmp() calls on 16-byte structs, so I think we can wire that up with a TLI hook that feeds into this. Differential Revision: https://reviews.llvm.org/D31156 llvm-svn: 298376

* [ADMGPU] SDWA peephole optimization pass.Sam Kolton2017-03-217-1/+720
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: First iteration of SDWA peephole. This pass tries to combine several instruction into one SDWA instruction. E.g. it converts: ''' V_LSHRREV_B32_e32 %vreg0, 16, %vreg1 V_ADD_I32_e32 %vreg2, %vreg0, %vreg3 V_LSHLREV_B32_e32 %vreg4, 16, %vreg2 ''' Into: ''' V_ADD_I32_sdwa %vreg4, %vreg1, %vreg3 dst_sel:WORD_1 dst_unused:UNUSED_PAD src0_sel:WORD_1 src1_sel:DWORD ''' Pass structure: 1. Iterate over machine instruction in basic block and try to apply "SDWA patterns" to each of them. SDWA patterns match machine instruction into either source or destination SDWA operand. E.g. ''' V_LSHRREV_B32_e32 %vreg0, 16, %vreg1''' is matched to source SDWA operand '''%vreg1 src_sel:WORD_1'''. 2. Iterate over found SDWA operands and find instruction that could be potentially coverted into SDWA. E.g. for source SDWA operand potential instruction are all instruction in this basic block that uses '''%vreg0''' 3. Iterate over all potential instructions and check if they can be converted into SDWA. 4. Convert instructions to SDWA. This review contains basic implementation of SDWA peephole pass. This pass requires additional testing fot both correctness and performance (no performance testing done). There are several ways this pass can be improved: 1. Make this pass work on whole function not only basic block. As I can see this can be done right now without changes to pass. 2. Introduce more SDWA patterns 3. Introduce mnemonics to limit when SDWA patterns should apply Reviewers: vpykhtin, alex-t, arsenm, rampitec Subscribers: wdng, nhaehnle, mgorny Differential Revision: https://reviews.llvm.org/D30038 llvm-svn: 298365
* [DebugInfo][X86] Teach Optimize LEAs pass to handle debug valuesAndrea Di Biagio2017-03-211-7/+11
| | | | | | | | | | | | | | | | This patch fixes an issue in the Optimize LEAs pass where redundant LEAs were not removed because they were being used by debug values. The debug values are now ignored when determining whether LEAs are redundant. For now the debug values for the redundant LEAs are marked as undefined, effectively lost. The intention is for a follow up patch which will attempt to preserve the debug values where possible. Patch by Andrew Ng. Differential Revision: https://reviews.llvm.org/D30835 llvm-svn: 298360

* [AVX-512] Handle kor/kand/kandn/kxor/kxnor/knot intrinsics at lowering time ↵Craig Topper2017-03-193-26/+40
| | | | | | | | | | | | | | | | | | | instead of isel Summary: Currently we handle these intrinsics at isel with special patterns. But as they just map to normal logic operations, we should just handle them at lowering. This will expose them to DAG combine optimizations. Right now the kor-sequence test generates a bunch of regclass copies between GR16 and VK16 that the peephole optimizer and/or register coallescing are removing to keep everything in the mask domain. By handling the logic op intrinsics earlier, these copies become bitcasts in the DAG and get removed by DAG combine which seems more robust. This should help enable my plan to stop copying between K registers and GR8/GR16. The peephole optimizer can't remove a chain of copies between K and GR32 with insert_subreg/extract_subreg present in the chain so the kor-sequence test break. But this patch should dodge the problem entirely.

However when the register mask is not from the static predefined list, there is no descriptor string and the printer fails. This patch adds support to custom register mask printing and dumping. Also the list of callee saved registers (describing the registers that must be preserved for the caller) might be dynamic. As such this data needs to be dumped and parsed back to the Machine Register Info. Differential Revision: https://reviews.llvm.org/D30971 llvm-svn: 298207
