strip: Ignore --reloc-debug-sections-only for non-ET_REL files.
strip --reloc-debug-sections-only is expected to be a no-op for non-ET_REL files. This was not enforced in the code. Sections were copied over to a new output file and normally its contents would be identical to the input file. However the output file is not identical to a non-ET_REL input file if the linker organized sections such that the indices of SHF_ALLOC sections are not in a contigous group. In this case strip will modify sections in order to keep all SHF_ALLOC sections in a contiguous group. Fix this by ignoring --reloc-debug-sections-only for non-ET_REL files. https://sourceware.org/bugzilla/show_bug.cgi?id=32253 Signed-off-by: Aaron Merey <[email protected]>
