H.J., I know, my patch *was* for PR38824. :-)  But I added two
peephole2, one for SImode (including the clobbering of CC, and with
additional replace_rtx handling) and one for MMX/SSE registers.  For
the record, the equivalent one for x87 regs was already there.

So restricting the problematic peephole to GENERAL_REGNO_P would not
cause PR38824 (for which there is a testcase).
