Subject: 	* elf.c (assign_file_positions_for_segments): For a loadable
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c63729b518f587e33434272bcdf2d2e47e016722;p=binutils-gdb.git

	* elf.c (assign_file_positions_for_segments): For a loadable
	section, make sure that the load address is correct relative to
	the load address of the segment plus the size of the segment so
	far.
