+ serving as fast replacements for fprintf integer to string conversions.
+ (sprint_ul_rev): Internal helper for the above.
+ (output_addr_const) <CONST_INT>: Don't use fprintf.
+ * varasm.c: Fix some whitespace inconsistencies.
+ (default_elf_asm_output_limited_string): New.
+ (default_elf_asm_output_ascii): Likewise.
+ (default_elf_internal_label): Likewise.
+ * config/elfos.h (ASM_GENERATE_INTERNAL_LABEL): Use sprint_ul and
+ stpcpy instead of sprintf.
(TARGET_ASM_INTERNAL_LABEL): Define as default_elf_internal_label.
- (ELF_ASCII_ESCAPES, ELF_STRING_LIMIT): Are the old ESCAPES and
+ (ELF_ASCII_ESCAPES, ELF_STRING_LIMIT): Rename from old ESCAPES and
STRING_LIMIT macros.
- (ASM_OUTPUT_LIMITED_STRING, ASM_OUTPUT_ASCII): Macros now just
- call respective functions that provide the same
- functionality. Those are default_elf_asm_output_limited_string()
- and default_elf_asm_output_ascii() in varasm.c.
- * varasm.c: Fixed some whitespace inconsistencies.
- (default_elf_asm_output_limited_string)
- (default_elf_asm_output_ascii): The above macros from elfos.h are
- implemented here as these functions, avoiding superfluous calls to
- fprintf().
- (default_elf_internal_label): Hook for
- targetm.asm_out.internal_label and ASM_OUTPUT_DEBUG_LABEL.
- * i386.c: Don't call fprintf("%u") but fprint_ul() instead.
- * defaults.h (ASM_OUTPUT_LABEL, ASM_OUTPUT_INTERNAL_LABEL):
- Expanded the macros on multiple lines for readability.
- (ASM_OUTPUT_LABELREF): Have two calls to fputs() instead of one to
- asm_fprintf().
- * dwarf2asm.c (dw2_assemble_integer, dw2_asm_output_data)
- (dw2_asm_data_uleb128, dw2_asm_delta_uleb128)
- (dw2_asm_delta_sleb128): Convert fprintf() calls to the new
- faster functions.
- * dwarf2out.c (dwarf2out_source_line): Convert fprintf() calls to
- the new faster functions.
+ (ASM_OUTPUT_LIMITED_STRING, ASM_OUTPUT_ASCII): Call functions that
+ provide the same functionality.
+ * config/i386/i386.c (print_reg): Call fprint_ul instead of fprintf.
