Subject: 	* config/tc-i386.c (output_jump, output_disp)
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=062cd5e7fc34f6b63e2672e21b9ee8c69ec358f0;p=binutils-gdb.git

	* config/tc-i386.c (output_jump, output_disp)
	(md_estimate_size_before_relax): Don't set fx_pcrel_adjust any
	more.
	(md_apply_fix3): Remember addend value for rela relocations.
	(tc_gen_reloc): Correctly compute pc-relative relocation addend.
