We already do; see print_switch_values in toplev.c for an example usage. In verbose mode, almost all the switches are dumped to stderr; if -fverbose-asm is used, they are dumped as comments to the assembly file. I say "dumped" when they're actually formatted nicely. And I say "almost" all the switches because the language-specific ones can't be seen. (I tried cleaning this up once for this specific purpose, but it involved touching a lot of files, and nobody was interested.) > They > in turn could easily still the options into a suitable ELF > section. I can't see any obvious documentation of .note sections in the gas source, and I don't see .command mentioned at all. I wouldn't mind playing with this idea while waiting on compiles, if you can point me towards some usage docs.
