Subject: Ignore degenerate PT_LOAD segments
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=325ba6fb34be799c885fad9287d883e86b835c84;p=binutils-gdb.git

Ignore degenerate PT_LOAD segments

Fixes a failure triggered by -z separate-code.  p_memsz is tested
rather than p_filesz for objcopy --only-keep-debug where p_filesz is
set to zero.

	PR 22845
	* elf.c (assign_file_positions_for_non_load_sections): Ignore
	degenerate zero size PT_LOAD segments when finding one overlapping
	the PT_GNU_RELRO segment.
