Because you either introduce a dependency on ROMCC or you need
additional assembler code. mmxstack/xmmstack+GCC is not an option here
because a microcode update may be required before using floating point
stuff.

If I had stood up a year ago and said "Let's introduce a ROMCC
dependency for all CAR boards", we would have seen a major flamewar. If
I had proposed to rewrite our CMOS code in assembler, the response would
not have been enthusiastic either.
