[mlir][tosa] Add support for cast_from/to_block_scaled (#163436) This commit adds support for the cast_from/to_block_scaled operations from the ext-mxfp extension. This includes: - Operation definition in TosaOps.td - Micro-scaling supported types definition - Shape inference and verifiers - Validation pass checks to ensure usage is only valid when the target environment includes ext-mxfp and at least v1.1.draft of the specification. Note: currently it excludes support for mxint8. This will be added in a later commit. Note: this commit adds support as defined in the spec in https://github.com/arm/tosa-specification/commit/063846a75b9687ab01e58cb3538472bffb3a03b0. EXT_MXFP extension is considered experimental and subject to breaking change. Co-authored-by: Tat Wai Chong <tatwai.chong@arm.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.
