93b135859d Removed files that are no longer used by the rewritten linker. 1993-12-30 19:57:49 +00:00
Ian Lance Taylor
4a6afc88bb A major rewrite to move the bulk of the linker into BFD so that
more efficient backend code can be written for specific object
	files.

	ldwarn.c, ldwarn.h, relax.c, relax.h: Removed.

f2f824ae57 * config/i386-linux.mt: delete ".sh" from genscripts argument
(change made to genscripts on July 21...)

This is all it took for linux-native ld to build. It isn't necessarily useful,
particularly as gcc is still configured to pass -m486 and -dll-verbose, which
this ld doesn't parse...
