-
- * config/tc-i386.c (output_insn): Save frag_now and frag_now_fix ()
- at start of insn, pass it to output_disp and output_imm.
- (output_disp): Added arguments. If _GLOBAL_OFFSET_TABLE_ is seen
- in displacement for R_386_32 reloc, use R_386_GOTPC and compute
- properly addend.
- (output_imm): Added arguments. Compute properly addend for
- R_386_GOTPC.
- (md_apply_fix3): Remove R_386_GOTPC handling.
- * testsuite/gas/i386/gotpc.s: New.
- * testsuite/gas/i386/gotpc.d: New.
- * testsuite/gas/i386/i386.exp: Add gotpc test.
