# when building for Arm64EC (#87542)
While attempting to build some Rust code, I was getting linker errors due to missing functions that are implemented in `compiler-rt`. Turns out that when `compiler-rt` is built for Arm64EC, all its function names are mangled with the leading `#`. This change removes the hard-coded list of library-implemented intrinsics to mangle for Arm64EC, and instead assumes that they all must be mangled.
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.
