* [AMDGPU] Assembler: Basic support for MIMGNikolay Haustov2016-02-261-6/+70
| | | | | | | | | | | Add parsing and printing of image operands. Matches legacy sp3 assembler. Change image instruction order to have data/image/sampler operands in the beginning. This is needed because optional operands in MC are always last. Update SITargetLowering for new order. Add basic MC test. Update CodeGen tests. Review: http://reviews.llvm.org/D17574 llvm-svn: 261995
* [AMDGPU] Assembler: Simplify handling of optional operandsNikolay Haustov2016-02-251-72/+59
| | | | | | | | | | | | | | | | | | | | | | Resubmit with index problem fixed. Verified with valgrind. Prepare to support DPP encodings. For DPP encodings, we want row_mask/bank_mask/bound_ctrl to be optional operands. However this means that when parsing instruction which has no mnemonic prefix, we cannot add both default values for VOP3 and for DPP optional operands to OperandVector - neither instructions would match. So add default values for optional operands to MCInst during conversion instead. Mark more operands as IsOptional = 1 in .td files. Do not add default values for optional operands to OperandVector in AMDGPUAsmParser. Add default values for optional operands during conversion using new helper addOptionalImmOperand. Change to cvtVOP3_2_mod to check instruction flag instead of presence of modifiers. In the future, cvtVOP3* functions can be combined into one. Separate cvtFlat and cvtFlatAtomic. Fix CNDMASK_B32 definition to have no modifiers. Review: http://reviews.llvm.org/D17445 llvm-svn: 261856

* [AMDGPU][llvm-mc] Support for 32-bit inline literalsTom Stellard2016-02-221-33/+58
| | | | | | | | | | | | | | | | | | | | | | | Patch by: Artem Tamazov Summary: Note: Support for 64-bit inline literals TBD Added: Support of abs/neg modifiers for literals (incomplete; parsing TBD). Added: Some TODO comments. Reworked/clarity: rename isInlineImm() to isInlinableImm() Reworked/robustness: disallow BitsToFloat() with undefined value in isInlinableImm() Reworked/reuse: isSSrc32/64(), isVSrc32/64() Tests added.

* [AMDGPU] Fix for "v_div_scale_f64 reg, vcc, ..." parsingTom Stellard2016-02-111-2/+2
| | | | | | | | | | | | | | | | | | Summary: Added support for "VOP3Only" attribute in VOP3bInst encoding. Set VOP3Only=1 for V_DIV_SCALE_F64/32 insns. Added support for multi-dest instructions in AMDGPUAs::cvt*(). Added lit test for "V_DIV_SCALE_F64|F32 vreg,vcc|sreg,vreg,vreg,vreg".

* [AMDGPU] Assembler: Fix VOP3 only instructionsTom Stellard2016-02-111-53/+92
| | | | | | | | | | | | | | | | | | | | | Separate methods to convert parsed instructions to MCInst: - VOP3 only instructions (always create modifiers as operands in MCInst) - VOP2 instrunctions with modifiers (create modifiers as operands in MCInst when e64 encoding is forced or modifiers are parsed) - VOP2 instructions without modifiers (do not create modifiers as operands in MCInst) - Add VOP3Only flag. Pass HasMods flag to VOP3Common. - Simplify code that deals with modifiers (-1 is now same as 0). This is no longer needed. - Add few tests (more will be added separately). Update error message now correct. Patch By: Nikolay Haustov Differential Revision: http://reviews.llvm.org/D16778 llvm-svn: 260483

* Reduce the size of MCRelaxableFragment.Akira Hatanaka2015-11-141-2/+4
| | | | | | | | | | | | | | | | | | | | | | MCRelaxableFragment previously kept a copy of MCSubtargetInfo and MCInst to enable re-encoding the MCInst later during relaxation. A copy of MCSubtargetInfo (instead of a reference or pointer) was needed because the feature bits could be modified by the parser. This commit replaces the MCSubtargetInfo copy in MCRelaxableFragment with a constant reference to MCSubtargetInfo. The copies of MCSubtargetInfo are kept in MCContext, and the target parsers are now responsible for asking MCContext to provide a copy whenever the feature bits of MCSubtargetInfo have to be toggled. With this patch, I saw a 4% reduction in peak memory usage when I compiled verify-uselistorder.lto.bc using llc. rdar://problem/21736951 Differential Revision: http://reviews.llvm.org/D14346 llvm-svn: 253127
