Does this assume having access to the exact version of the compiler use, or can it be done with a different compiler in practice?
And do you care about things like binary layout, or just instruction match? (Does that ever matter in practice?)
- dezgeg 3mo agoYes, exact version of the original compiler is required. Generally bit-for-bit equivalence to the original executable is expected. However I think for some cases where the original executable included debug info (eg. PS2 ELFs) then the unused-at-runtime sections need not match.
