Subject: 	* config/tc-arm.c (md_begin): Remove ARM_PLT32 reloc associated
X-Git-Tag: gdb_7_4-2011-12-13-branchpoint~372
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3da1d841a1e0a8d5dcc6d41176c65ee7698982c8;p=external%2Fbinutils.git

	* config/tc-arm.c (md_begin): Remove ARM_PLT32 reloc associated
	with the (PLT) instruction suffix when operating in eabi mode.
	* doc/c-arm.texi (ARM_Relocations): Extend description of (PLT)
	suffix.

	* gas/arm/pic.d: Update expected output.
