Subject: RE:  internal compiler error with bogus asm output constraint

Where can I find some documentation on using this extended asm format? I
have read all the GNU docs on it and can not understand how to use it.

Thanks,

Dave

Confirmed. This is triggered by a bogus argument for an output constraint.
Not a regression.

void f() {
  __asm__ (""  : "=r" ("r5"), "+r" ("r5"));
}
