--- Comment #7 from Taylor R Campbell <campbell+gcc-bugzilla at mumble dot net> --- > Sorry, no, NetBSD/sparc is too obscure a platform to justify changing the > default for the entire compiler. But you can do like Linux & Solaris and > add sparc/tso.h to the tm_file list of sparc-*-netbsdelf*) in config.gcc. I don't understand, how would that help? As I understand it, whenever `-mcpu=v7', the memory model is just ignored -- even if we set it to TSO -- because all rules that depend on it are gated on TARGET_V8 || TARGET_V9 or similar. I'm not asking for you to change defaults in Linux or Solaris -- I'm just asking to be _able_ to say `-mcpu=v7 -mmemory-model=tso' and get v7-only instruction streams with the LDSTUBs needed for TSO. Right now, with `-mcpu=v7', passing `-mmemory-model=tso' has no effect.
