Hi, This adds another test case for the SH div0s insn utilization. Tested with make -k check-gcc RUNTESTFLAGS="sh.exp=pr52933* --target_board=sh-sim \{-m2/-ml,-m2/-mb,-m2a/-mb,-m4/-ml,-m4/-mb,-m4a/-ml,-m4a/-mb}" Committed as r219017. Cheers, Oleg gcc/testsuite/ChangeLog: PR target/52933 * gcc.target/sh/sh/pr52933-3.c: New.
