* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* AMDGPU: Separate R600 and GCN TableGen filesTom Stellard2018-06-281-0/+1
| | | | | | | | | | | | | | | | | | | | | Summary: We now have two sets of generated TableGen files, one for R600 and one for GCN, so each sub-target now has its own tables of instructions, registers, ISel patterns, etc. This should help reduce compile time since each sub-target now only has to consider information that is specific to itself. This will also help prevent the R600 sub-target from slowing down new features for GCN, like disassembler support, GlobalISel, etc. Reviewers: arsenm, nhaehnle, jvesely Reviewed By: arsenm Subscribers: MatzeB, kzhuravl, wdng, mgorny, yaxunl, dstuttard, tpr, t-tye, javed.absar, llvm-commits Differential Revision: https://reviews.llvm.org/D46365 llvm-svn: 335942
* AMDGPU: Refactor MIMG instruction TableGen using generic tablesNicolai Haehnle2018-06-211-9/+5
| | | | | | | | | | | | | | | | | | | | Summary: This allows us to access rich information about MIMG opcodes from C++ code. Simplifying the mapping between equivalent opcodes of different data size becomes quite natural. This also flattens the MIMG-related class and multiclass hierarchy a little, and collapses together some of the scaffolding for sample and gather4 opcodes.

* AMDGPU: Turn D16 for MIMG instructions into a regular operandNicolai Haehnle2018-06-211-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This allows us to reduce the number of different machine instruction opcodes, which reduces the table sizes and helps flatten the TableGen multiclass hierarchies. We can do this because for each hardware MIMG opcode, we have a full set of IMAGE_xxx_Vn_Vm machine instructions for all required sizes of vdata and vaddr registers. Instead of having separate D16 machine instructions, a packed D16 instructions loading e.g. 4 components can simply use the same V2 opcode variant that non-D16 instructions use. We still require a TSFlag for D16 buffer instructions, because the D16-ness of buffer instructions is part of the opcode. Renaming the flag should help avoid future confusion. The one non-obvious code change is that for gather4 instructions, the disassembler can no longer automatically decide whether to use a V2 or a V4 variant. The existing logic which choose the correct variant for other MIMG instruction is extended to cover gather4 as well. As a bonus, some of the assembler error messages are now more helpful (e.g., complaining about a wrong data size instead of a non-existing instruction). While we're at it, delete a whole bunch of dead legacy TableGen code.

* AMDGPU: Remove #include "MCTargetDesc/AMDGPUMCTargetDesc.h" from common headersTom Stellard2018-05-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: MCTargetDesc/AMDGPUMCTargetDesc.h contains enums for all the instuction and register defintions, which are huge so we only want to include them where needed. This will also make it easier if we want to split the R600 and GCN definitions into separate tablegenerated files. I was unable to remove AMDGPUMCTargetDesc.h from SIMachineFunctionInfo.h because it uses some enums from the header to initialize default values for the SIMachineFunction class, so I ended up having to remove includes of SIMachineFunctionInfo.h from headers too.

* [AMDGPU] Improve disassembler error handlingTim Corringham2018-03-261-1/+4
| | | | | | | | | | | | | | | | | | | | | | Summary: llvm-objdump now disassembles unrecognised opcodes as data, using the .long directive. We treat unrecognised opcodes as being 32 bit values, so move along 4 bytes rather than the single byte which previously resulted in a cascade of bogus disassembly following an unrecognised opcode. While no solution can always disassemble code that contains embedded data correctly this provides a significant improvement. The disassembler will now cope with an arbitrary length section as it no longer truncates it to a multiple of 4 bytes, and will use the .byte directive for trailing bytes.

* AMDGPU: Partially fix disassembly of MIMG instructionsMatt Arsenault2017-12-131-1/+41
| | | | | | | | | | | | | | | | | | | | | Stores failed to decode at all since they didn't have a DecoderNamespace set. Loads worked, but did not change the register width displayed to match the numbmer of enabled channels. The number of printed registers for vaddr is still wrong, but I don't think that's encoded in the instruction so there's not much we can do about that. Image atomics are still broken. MIMG is the same encoding for SI/VI, but the image atomic classes are split up into encoding specific versions unlike every other MIMG instruction. They have isAsmParserOnly set on them for some reason. dmask is also special for these, so we probably should not have it as an explicit operand as it is now. llvm-svn: 320614

* Sort the remaining #include lines in include/... and lib/....Chandler Carruth2017-06-061-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787

| | | | | | | | | | | | | | | | | | Since 32-bit instructions with 32-bit input immediate behavior are used to materialize 16-bit constants in 32-bit registers for 16-bit instructions, determining the legality based on the size is incorrect. Change operands to have the size specified in the type. Also adds a workaround for a disassembler bug that produces an immediate MCOperand for an operand that is supposed to be OPERAND_REGISTER. The assembler appears to accept out of bounds immediates and truncates them, but this seems to be an issue for 32-bit already. llvm-svn: 289306
* AMDGPU: Disallow exec as SMEM instruction operandMatt Arsenault2016-11-291-4/+9
| | | | | | | | | | | | | | | | | | | This is not in the list of valid inputs for the encoding. When spilling, copies from exec can be folded directly into the spill instruction which results in broken stores. This only fixes the operand constraints, more codegen work is required to avoid emitting the invalid spills. This sort of breaks the dbg.value test. Because the register class of the s_load_dwordx2 changes, there is a copy to SReg_64, and the copy is the operand of dbg_value. The copy is later dead, and removed from the dbg_value. llvm-svn: 288191

* AMDGPU: Expand register indexing pseudos in custom inserterMatt Arsenault2016-07-191-0/+5
| | | | | | | | | | | | | | | | | | | | | | | This is to help moveSILowerControlFlow to before regalloc. There are a couple of tradeoffs with this. The complete CFG is visible to more passes, the loop body avoids an extra copy of m0, vcc isn't required, and immediate offsets can be shrunk into s_movk_i32. The disadvantage is the register allocator doesn't understand that the single lane's vector is dead within the loop body, so an extra register is used to outlive the loop block when expanding the VGPR -> m0 loop. This also now results in worse waitcnt insertion before the loop instead of after for pending operations at the point of the indexing, but that should be fixed by future improvements to cross block waitcnt insertion. v_movreld_b32's operands are now modeled more correctly since vdst is not a true output. This is kind of a hack to treat vdst as a use operand. Extra checking is required in the verifier since I can't seem to get tablegen to emit an implicit operand for a virtual register. llvm-svn: 275934
