search for: layoutsections

...ting address ranges: this is very difficult due to many implicit inter-section references. If you have an advanced binary rewriting tool, this is still doable, but definitely brittle. File offsets (p_offset,sh_offset) can be reconstructed from addresses. llvm-objcopy/ELF/Object.cpp layoutSections has some code. A more sophisticated implementation is in the linker: lld/ELF/Writer.cpp assignFileOffsets

Hey, LLVM has logic to parse ELF and PE binaries using `llvm::object::createBinary`. I tried to search in the codebase to see if there's a possibility to add/remove sections after parsing a binary and re-write the binary to another location. Basically, like what llvm-objcopy does. Can you point me to the right classes to look into, if this is something that LLVM has? Many thanks Joseph
