It most probably would.  How do callbacks, say for example in the
signal handing code of QEMU, retreive the EFLAGS value from the CC_*
variables?  Do it call some function that calculates the value, or
does the main loop calculate the full EFLAGS value whenever it breaks
out of a sequence of translated blocks to handle signals?
