* [TableGen] Remove unused target intrinsic generation logicReid Kleckner2019-12-111-12/+0
| | | | | | | | | | | | AMDGPU was the last in tree target to use this tablegen mode. I plan to split up the global intrinsic enum similar to the way that clang diagnostics are split up today. I don't plan to build on this mode. Reviewers: arsenm, echristo, efriedma Reviewed By: echristo Differential Revision: https://reviews.llvm.org/D71318

* Use InitLLVM to setup a pretty stack printerRui Ueyama2019-11-261-2/+2
| | | | | | | | | | | | | | InitLLVM does not only save a few lines from main() but also makes the commands do the right thing for multibyte character pathnames on Windows (i.e. canonicalize argv's to UTF-8) because of the code we have in this file: https://github.com/llvm/llvm-project/blob/master/llvm/lib/Support/InitLLVM.cpp#L32 For many LLVM commands, we already have calls of InitLLVM, but there are still remainings.

* [TableGen] Add backend to generate command guide for tools using libOption.Jonas Devlieghere2019-11-221-2/+6
| | | | | | | | | | | | For lldb and dsymutil, the command guide is essentially a copy of its help output generated by libOption. Making sure the two stay in sync is tedious and error prone. Given that we already generate the help from a tablegen file, we might as well generate the RST as well. This adds a tablegen backend for generating Sphinx/RST command guides from the tablegen file.

* [TableGen] Introduce a generic automaton (DFA) backendJames Molloy2019-10-041-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch introduces -gen-automata, a backend for generating deterministic finite-state automata. DFAs are already generated by the -gen-dfa-packetizer backend. This backend is more generic and will hopefully be used to implement the DFA generation (and determinization) for the packetizer in the future. This backend allows not only generation of a DFA from an NFA (nondeterministic finite-state automaton), it also emits sidetables that allow a path through the DFA under a sequence of inputs to be analyzed, and the equivalent set of all possible NFA transitions extracted. This allows a user to not just answer "can my problem be solved?" but also "what is the solution?". Clearly this analysis is more expensive than just playing a DFA forwards so is opt-in. The DFAPacketizer has this behaviour already but this is a more compact and generic representation. Examples are bundled in unittests/TableGen/Automata.td. Some are trivial, but the BinPacking example is a stripped-down version of the original target problem I set out to solve, where we pack values (actually immediates) into bins (an immediate pool in a VLIW bundle) subject to a set of esoteric constraints.

* [gicombiner] Add the boring boilerplate for the declarative combinerDaniel Sanders2019-10-021-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is the first of a series of patches extracted from a much bigger WIP patch. It merely establishes the tblgen pass and the way empty combiner helpers are declared and integrated into a combiner info. The tablegen pass takes a -combiners option to select the combiner helper that will be generated. This can be given multiple values to generate multiple combiner helpers at once. Doing so helps to minimize parsing overhead. The reason for creating a GlobalISel subdirectory in utils/TableGen is that there will be quite a lot of non-pass files (~15) by the time the patch series is done.

* [tblgen] Add a timer covering the time spent reading the Instruction defsDaniel Sanders2019-02-111-0/+11
| | | | | | | | | | | | | | | This patch adds a -time-regions option to tablegen that can enable timers (currently only one) that assess the performance of tablegen itself. This can be useful for identifying scaling problems with tablegen backends. This particular timer has allowed me to ignore time that is not attributed the GISel combiner pass. It's useful by itself but it is particularly useful in combination with https://reviews.llvm.org/D52954 which causes this period of time to be annotated within Xcode Instruments which in turn allows profile samples and recorded allocations attributed to reading instructions to be filtered out. llvm-svn: 353763
* 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

* [TableGen] Add a general-purpose JSON backend.Simon Tatham2018-07-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The aim of this backend is to output everything TableGen knows about the record set, similarly to the default -print-records backend. But where -print-records produces output in TableGen's input syntax (convenient for humans to read), this backend produces it as structured JSON data, which is convenient for loading into standard scripting languages such as Python, in order to extract information from the data set in an automated way. The output data contains a JSON representation of the variable definitions in output 'def' records, and a few pieces of metadata such as which of those definitions are tagged with the 'field' prefix and which defs are derived from which classes. It doesn't dump out absolutely every piece of knowledge it _could_ produce, such as type information and complicated arithmetic operator nodes in abstract superclasses; the main aim is to allow consumers of this JSON dump to essentially act as new backends, and backends don't generally need to depend on that kind of data. The new backend is implemented as an EmitJSON() function similar to all of llvm-tblgen's other EmitFoo functions, except that it lives in lib/TableGen instead of utils/TableGen on the basis that I'm expecting to add it to clang-tblgen too in a future patch. To test it, I've written a Python script that loads the JSON output and tests properties of it based on comments in the .td source - more or less like FileCheck, except that the CHECK: lines have Python expressions after them instead of textual pattern matches.

* [IR] Split Intrinsics.inc into enums and implementationsReid Kleckner2018-06-231-8/+20
| | | | | | | | | | | | | | | | | | | Implements PR34259 Intrinsics.h is a very popular header. Most LLVM TUs care about things like dbg_value, but they don't care how they are implemented. After I split these out, IntrinsicImpl.inc is 1.7 MB, so this saves each LLVM TU from scanning 1.7 MB of source that gets pre-processed away. It also means we can modify intrinsic properties without triggering a full rebuild, but that's probably less of a win. I think the next best thing to do would be to split out the target intrinsics into their own header. Very, very few TUs care about target-specific intrinsics. It's very hard to split up the target independent intrinsics like llvm.expect, assume, and dbg.value, though. llvm-svn: 335407
* [RISCV] Tablegen-driven Instruction Compression.Sameer AbuAsal2018-04-061-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch implements a tablegen-driven Instruction Compression mechanism for generating RISCV compressed instructions (C Extension) from the expanded instruction form. This tablegen backend processes CompressPat declarations in a td file and generates all the compile-time and runtime checks required to validate the declarations, validate the input operands and generate correct instructions. The checks include validating register operands, immediate operands, fixed register operands and fixed immediate operands. Example: class CompressPat<dag input, dag output> { dag Input = input; dag Output = output; list<Predicate> Predicates = []; } let Predicates = [HasStdExtC] in { def : CompressPat<(ADD GPRNoX0:$rs1, GPRNoX0:$rs1, GPRNoX0:$rs2), (C_ADD GPRNoX0:$rs1, GPRNoX0:$rs2)>; } The result is an auto-generated header file 'RISCVGenCompressEmitter.inc' which exports two functions for compressing/uncompressing MCInst instructions, plus some helper functions: bool compressInst(MCInst& OutInst, const MCInst &MI, const MCSubtargetInfo &STI, MCContext &Context); bool uncompressInst(MCInst& OutInst, const MCInst &MI, const MCRegisterInfo &MRI, const MCSubtargetInfo &STI); The clients that include this auto-generated header file and invoke these functions can compress an instruction before emitting it, in the target-specific ASM or ELF streamer, or can uncompress an instruction before printing it, when the expanded instruction format aliases is favored. The following clients were added to implement compression\uncompression for RISCV: 1) RISCVAsmParser::MatchAndEmitInstruction: Inserted a call to compressInst() to compresses instructions parsed by llvm-mc coming from an ASM input. 2) RISCVAsmPrinter::EmitInstruction: Inserted a call to compressInst() to compress instructions that were lowered from Machine Instructions (MachineInstr). 3) RVInstPrinter::printInst: Inserted a call to uncompressInst() to print the expanded version of the instruction instead of the compressed one (e.g, add s0, s0, a5 instead of c.add s0, a5) when -riscv-no-aliases is not passed.

* [X86][TableGen] Recommitting the X86 memory folding tables TableGen backend ↵Ayman Musa2017-10-081-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | while disabling it by default. After the original commit ([[ https://reviews.llvm.org/rL304088 | rL304088 ]]) was reverted, a discussion in llvm-dev was opened on 'how to accomplish this task'. In the discussion we concluded that the best way to achieve our goal (which is to automate the folding tables and remove the manually maintained tables) is: # Commit the tablegen backend disabled by default. # Proceed with an incremental updating of the manual tables - while checking the validity of each added entry. # Repeat previous step until we reach a state where the generated and the manual tables are identical. Then we can safely remove the manual tables and include the generated tables instead. # Schedule periodical (1 week/2 weeks/1 month) runs of the pass: - if changes appear (new entries): - make sure the entries are legal - If they are not, mark them as illegal to folding - Commit the changes (if there are any). CMake flag added for this purpose is "X86_GEN_FOLD_TABLES". Building with this flags will run the pass and emit the X86GenFoldTables.inc file under build/lib/Target/X86/ directory which is a good reference for any developer who wants to take part in the effort of completing the current folding tables.

* [x86] Revert the X86FoldTablesEmitter due to more miscompiles.Chandler Carruth2017-06-061-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In testing, we've found yet another miscompile caused by the new tables. And this one is even less clear how to fix (we could teach it to fold a 16-bit load instead of the 32-bit load it wants, or block folding entirely). Also, the approach to excluding instructions seems increasingly to not scale well. I have left a more detailed analysis on the review log for the original patch (https://reviews.llvm.org/D32684) along with suggested path forward. I will land an additional test case that I wrote which covers the code that was miscompiling (folding into the output of `pextrw`) in a subsequent commit to keep this a pure revert. For each commit reverted here, I've restricted the revert to the non-test code touching the x86 fold table emission until the last commit where I did revert the test updates. This means the *new* test cases added for `insertps` and `xchg` remain untouched (and continue to pass).
