[LOH] Don't emit AdrpAddStr when register could be clobbered (#142849) https://github.com/llvm/llvm-project/commit/b783aa89795635cbe7b25b4143b562931fcec9f6 added a check to ensure an `AdrpAddLdr` LOH isn't created when there is an instruction between the `add` and `ldr` https://github.com/llvm/llvm-project/blob/50c5704dc000cc0af41a511aa44db03233edf0af/llvm/lib/Target/AArch64/AArch64CollectLOH.cpp#L419-L431 We need a similar check for `AdrpAddStr`. Although this technically isn't implemented in LLD, it could be in the future. https://github.com/llvm/llvm-project/blob/50c5704dc000cc0af41a511aa44db03233edf0af/lld/MachO/Arch/ARM64.cpp#L699-L702
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.
