[LoongArch] Ensure .dwo sections do not contain relocations (#187429) When linker relaxation is enabled, LoongArchAsmBackend may emit relocations for same-section symbol differences, even when the fixup is in a .dwo section. This leads to errors such as: error: A dwo section may not contain relocations Split DWARF (.dwo) sections must not contain relocations. Fix this by resolving such fixups immediately when they are emitted into .dwo sections, even if the referenced symbols are in relaxable sections. This avoids generating invalid relocations in .debug_*.dwo sections when compiling with -gsplit-dwarf and -mrelax. Fixes #187428 (cherry picked from commit 89d8fe9d08c395875cf1201feaf9d213cadeea7a)
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.
