Subject: 	* ldexp.c, ldlang.c: added new idea "abs_output_section", removes
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ffc500322549fb0747a8d66a0364c8964f02d3c7;p=binutils-gdb.git

	* ldexp.c, ldlang.c: added new idea "abs_output_section", removes
	tests for NULL pointers all over the place.
	* ldlang.c (lang_process): remember to relocate global symbols
	*after* relaxing has done it stuff.
