--- Comment #6 from Kazumoto Kojima <kkojima at gcc dot gnu.org> 2012-10-12 00:13:51 UTC --- (In reply to comment #5) > Kaz, do you happen to know something regarding this matter? My SH4 software manual says for STC that all stc/stc.l instructions except stc gbr,rn/stc gbr,@-rn are privileged instructions which might cause an illegal exception in user mode. LDC has a similar remark.
