Subject: 	* elfcode.h (map_program_segments): ELF program header entries
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2f3189e737abcea61560a470c0845a9c4c498c3f;p=binutils-gdb.git

	* elfcode.h (map_program_segments): ELF program header entries
	must be sorted by load address.  This used to generate the entries
	in reverse order.
