+ FIXME: GCC makes a distinction between -mcpu=FOO and -mFOO:
+ -mcpu=FOO schedules for FOO, but still produces code that meets the
+ requirements of MIPS ISA I. For example, it won't generate any
+ FOO-specific instructions, and it will still assume that any
+ scheduling hazards described in MIPS ISA I are there, even if FOO
+ has interlocks. -mFOO gives GCC permission to generate code that
+ will only run on a FOO; it will generate FOO-specific instructions,
+ and assume interlocks provided by a FOO.

-static int mips_5900 = -1;
+ However, GAS currently doesn't make this distinction; before Jan 28
+ 1999, GAS's -mcpu=FOO implied -mFOO, which violates GCC's
+ assumptions. The GCC driver passes these flags through to GAS, so
+ if GAS actually does anything that doesn't meet MIPS ISA I with
+ -mFOO, then GCC's -mcpu=FOO flag isn't going to work.
-/* end-sanitize-r5900 */
-/* Whether Toshiba r3900 instructions are permitted. */
-static int mips_3900 = -1;
+ And furthermore, it did not assume that -mFOO implied -mcpu=FOO,
+ which seems senseless --- why generate code which will only run on
+ a FOO, but schedule for something else?
-/* start-sanitize-tx49 */
