[lldb] Fix loading UUIDs from ELF headers. (#117028) A previous patch added the ability to load UUID from ELF headers using the program header and finding PT_NOTE entries. The fix would attempt to read the data for the PT_NOTE from memory, but it didn't slide the address so it ended up only working for the main executable if it wasn't moved in memory. This patch slides the address and adds logging. All processes map the ELF header + program headers + some program header contents into memory. The program header for the `PT_NOTE` entries are mapped, but the p_vaddr doesn't get relocated and is relative to the load address of the ELF header. So we take a "p_vaddr" (file address) and convert it into a load address in the process so we can load the correct bytes that contain the `PT_NOTE` contents.
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.
