[llvm-objcopy] Let --change-section-lma change segments wth filesz=0,… (#127724) … memsz>0 Currently, segments with a file size of 0 are ignored for the purposes of --change-section-lma, regardless of their memory size. It seems reasonable to me to modify such segments given that we're changing the LMA for all sections and these LMAs may be used during loading. GNU objcopy also seems to adjust such segments. Additionally, segments with file size > 0 and memory size = 0 will no longer be modified for the purposes of --change-section-lma as they shouldn't be part of the loaded memory image. Fixes #124680
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.
