2025-04-13[StrTable] Use string literal emission for intrinsics on non-MSVC platforms ↵Reid Kleckner
(#124856) This mainly transitions the LLVM intrinsic string table from character emission to string literal emission, which I confirmed happens for me locally. I moved the guts of StringToOffsetTable to a cpp file so I could move the `EmitLongStrLiterals` cl::opt global to a non-vague linkage home in the `TableGen` library. I had to add missing FormatVariadic.h includes to account for moving other includes to a cpp file.
2025-01-27[TableGen] Add assert to validate `Objects` list for `HwModeSelect` (#123794)Rahul Joshi
- Bail out of TableGen if any asserts fail before running the backend. - Add asserts to validate that the `Objects` and `Modes` lists for various `HwModeSelect` subclasses are of same length. - Eliminate equivalent check in CodeGenHWModes.cpp
2024-10-04[TableGen] Factor out timer code into a new `TGTimer` class (#111054)Rahul Joshi
Factor out the timer related functionality from `RecordKeeper` to a new `TGTimer` class in a new file.
2024-08-26[TableGen] Allow emitter callbacks to use `const RecordKeeper &` (#104716)Rahul Joshi
- Refactor TableGen backend options to allow specifying a callback function that takes either a const reference or a non-const reference to `RecordKeeper`. This will enable gradual migration of code to use const references and pointers to `RecordKeeper` and `Record` in the TableGen backends. - Refactor handling of the callback command line options. Move variable for the command line option from the header to the CPP file, and add a function `ApplyCallback` to apply the selected callback. - Change callbacks in TableGen.cpp to take const reference. They use the `Opt` class to register their callbacks. - Change IntrinsicEmitter to use the `OptClass` to define its callbacks. It already uses a const reference in the implementation.
2024-07-03[llvm] Avoid 'raw_string_ostream::str' (NFC)Youngsuk Kim
Since `raw_string_ostream` doesn't own the string buffer, it is desirable (in terms of memory safety) for users to directly reference the string buffer rather than use `raw_string_ostream::str()`. Work towards TODO comment to remove `raw_string_ostream::str()`.

2023-03-21TableGen: Introduce `llvm::TableGen::Emitter` to register backendsNAKAMURA Takumi
`Opt(flag, func, desc)` registers an option into `Action`. `OptClass<EmitterC>` is also available if `EmitterC(RK).run(OS)` is capable. `Action` is defined as `ManagedStatic<cl::opt>` to guarantee to be created when each registration of emitter is invoked. `llvm::TableGenMain(argv0, MainFn)` invokes `Action` instead of `MainFn` Differential Revision: https://reviews.llvm.org/D144351

2019-11-20Tablegen: Remove the error for duplicate include files.River Riddle
This error was originally added a while(7 years) ago when including multiple files was basically always an error. Tablegen now has preprocessor support, which allows for building nice c/c++ style include guards. With the current error being reported, we unfortunately need to double guard when including files: * In user of MyFile.td #ifndef MYFILE_TD include MyFile.td #endif * In MyFile.td #ifndef MYFILE_TD #define MYFILE_TD ... #endif Differential Revision: https://reviews.llvm.org/D70410

2019-01-19Update the file headers across all of the LLVM projects in the monorepoChandler Carruth
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
2018-12-19Let TableGen write output only if it changed, instead of doing so in cmake, ↵Nico Weber
attempt 2 This relands r330742: """ Let TableGen write output only if it changed, instead of doing so in cmake. Removes one subprocess and one temp file from the build for each tablegen invocation. No intended behavior change. """ In particular, if you see rebuilds after this change that you didn't see before this change, that's unintended and it's fine to revert this change again (but let me know). r330742 got reverted because some people reported that llvm-tblgen ran on every build after it. This could happen if the depfile output got deleted without deleting the main .inc output. To fix, make TableGen always write the depfile, but keep writing the main .inc output only if it has changed. This matches what we did in cmake before.

2018-05-07Revert r330742: Let TableGen write output only if it changed, instead of ↵Chandler Carruth
doing so in cmake. This change causes us to re-run tablegen for every single target on every single build. This is much, much worse than the problem being fixed AFAICT. On my system, it makes a clean rebuild of `llc` with nothing changed go from .5s to over 8s. On systems with less parallelism, slower file systems, or high process startup overhead this will be even more extreme. The only way I see this could be a win is in clean builds where we churn the filesystem. But I think incremental rebuild is more important, and so if we want to re-instate this, it needs to be done in a way that doesn't trigger constant re-runs of tablegen. llvm-svn: 331702
