Using virtual FPSCR registers to model insn dependencies
Updated patch that avoids the single_set problems by using (clobber (reg:SI
FPSCR_STAT_REG)) instead of a set. This also eliminates the fsca pattern
changes in the previous patch. Since the 'fpu_switch' insn is still a multiple
set insn, it won't be used for delay slot stuffing, but this is a minor issue
that can be addressed later. I'm testing the patch now on sh-sim. At least
'make all' works.
