[MCA] Extend -instruction-tables option with verbosity levels (#130574) Option becomes: -instruction-tables=`<level>` The choice of `<level>` controls number of printed information. `<level>` may be `none` (default), `normal`, `full`. Note: If the option is used without `<label>`, default is `normal` (legacy). When `<level>` is `full`, additional information are: - `<Bypass Latency>`: Latency when a bypass is implemented between operands in pipelines (see SchedReadAdvance). - `<LLVM Opcode Name>`: mnemonic plus operands identifier. - `<Resources units>`: Used resources associated with LLVM Opcode. - `<instruction comment>`: reports comment if any from source assembly. Level `full` can be used to better check scheduling info when TableGen is modified. LLVM Opcode name help to find right instruction regexp to fix TableGen Scheduling Info. -instruction-tables=full option is validated on AArch64/Neoverse/V1-sve-instructions.s Follow up of MR #126703 --------- Co-authored-by: Julien Villette <julien.villette@sipearl.com>
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
