If I'm not mistaken, they are macros.  Is it a problem to have them as
macros?

?

/* ISA has branch likely instructions (eg. mips2). */
/* Disable branchlikely for tx39 until compare rewrite.  They haven't
   been generated up to this point.  */
#define ISA_HAS_BRANCHLIKELY    (mips_isa != 1                          \
                                 /* || TARGET_MIPS3900 */)

I don't see how they wind up with branch likely instruction support.
mips I didn't have them, and the 3900 is a mips I part (mostly).

I'm sure Eric has more state than I.
