Those makefile rules are messy indeed, and what prompted me to consider looking into this stuff: I just had a mips-sgi-irix6.5 bootstrap break for me because the generated tp-bit.c was corrupted, most likely because both multilibs created the file quasi-simultaneously, mangling it in the process. > dfp-bit.* and fixed-bit.* can probably move along with fp-bit.* (or > before, or after), and I don't think there are any complicated issues > around those files. I'll have a look. I may move them together if I have to touch many of the same t-* files for that anyway.
