Note: This patch is distinct from the previous one titled
"[llvm-mca] Move bad-input.s test to be target specific"
This is a followup to #90474 and commit
afc10fc9b7
Context: Builders failing because they're unable to run the failure
test.
This still doesn't work in various circumstances, it seems MCA doesn't
want to run on a wide variety of hosts in various configurations, so
stick to the tried and tested method and pass -mtriple and -mcpu.
The LLVM Compiler Infrastructure
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.
