[Support] Extract simple suffix from GlobPattern (#162118) Existing glob is optimized with prefix for "src:/dir1/dir2/*", but I notices we often use patterns like "src:*dir1/dir2/file.h". So suffix will help. It will be hard to notice in most cases, but I use ignore list to bisect some falures. E.g. put 100k entries in the file, and build/test as needed. On one of hard compilation units glob matching was 400s, after the change 20s. Still, there is higher level inefficiency in ignore list matching, which I will address in followup patches and remove 20s above.
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.
