From 5cb6195d3bdc79f4038156fa0d87b69ffa1610d2 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Sat, 4 Apr 1998 12:25:44 -0800 Subject: [PATCH] i386.c (asm_output_function_prefix, [...]): Use ASM_GENERATE_INTERNAL_LABEL properly. * i386.c (asm_output_function_prefix, load_pic_register): Use ASM_GENERATE_INTERNAL_LABEL properly. (output_pic_addr_const): Recognize %X to supress any PIC sym suffix. (print_operand): Ignore it. (load_pic_register): Use it for the got load call. * i386.md (prologue_set_got, prologue_get_pc): Likewise. (prologue_get_pc_and_set_got): Likewise. * i386.h: Update print_operand docs.
