I am seeing the same thing. The issues is basically that after the no_new_pseudoes change mips_split_symbol through mips_force_temporary will create new pseudos during combine. The regnumber of these regs will address out of the reg_stat array in combine. This is incorrect as in combine you are supposed to use the scratch register that combine provides through a clobber clause which AFAIK is always an existing pseudo. I am planning to fix this by changing mips_split_symbol to use the scratch register instead of a new pseudo when invoked from a splitter. I will try to get the patch tested overnight. Adam
