common.opt (record-gcc-switches): New command line switch.
* common.opt (record-gcc-switches): New command line switch.
* target.h (print_switch_type): New enum.
(print_switch_fn_type): New typedef for a function pointer.
(struct gcc_target): Add record_gcc_switches and record_gcc_switches_section fields.
* target-def.h (TARGET_ASM_RECORD_GCC_SWITCHES): Provide a default definition.
(TARGET_ASM_RECORD_GCC_SWITCHES_SECTION): Provide a default definition.
* toplev.c (print_single_switch): Simplify by providing a pointer to function that will format and output the switch appropriately.
(print_switch_values): Likewise.
(print_to_asm_out_file): New function.
(print_to_stderr): New function.
(init_asm_output): If flag_record_gcc_switches is set then if the target supports recording the switches then emit them into the assembler output file, otherwise tell the user that the switch is not supported.
* varasm.c (eld_record_gcc_switches): New function. Example handler for the record_gcc_switches target hook.
* doc/tm.texi (TARGET_ASM_RECORD_GCC_SWITCHES): Document the new target hook.
(TARGET_ASM_RECORD_GCC_SWITCHES_SECTION): Likewise.
* doc/invoke.texi (-frecord-gcc-switches): Document.
