Browse Source 
* gencodes.c (output_predicate_decls): New function.
(main): Call it.
* machmode.h (GET_MODE_MASK): Arrange for it to be defined
even if it is not the first time machmode.h is #included.
* config/sh/sh.c (fpul_operand): Declare MODE argument.
* tm.texi (PREDICATE_CODES): Document predicate declarations.
* gcc.texi (Copyright): Added 2001.
