* emit-rtl.c (init_emit_once): Initialize modes first.
Sun Sep 19 01:23:23 1999 Alex Samuel <samuel@codesourcery.com>
* config/i386/i386.c (pic_label_name): Change to char pointer.
(global_offset_table): New variable.
(load_pic_register): Fill global_offset_table if it hasn't
already been done. Allocate pic_label_name dynamically.
* ggc.h (empty_string): New variable.
* ggc-simple.c (empty_string): Likewise.
(init_ggc): Allocate empty_string and add as root.
* stmt.c (digit_strings): New variable.
(init_stmt): Add last_block_end_note as root. Allocate and
initialize digit_strings.
(expand_asm_operands): Use empty_string instead of string
constant. Use digit_strings instead of string constants.
* profile.c (init_arc_profiler): Allocate string with
ggc_alloc_string instead of xmalloc.
(output_func_start_profiler): Likewise.
* c-typeck.c (digest_init): Check if init is error_mark_node.
