Hi, This adds some known-to-work test cases from the PR. Tested on sh-elf with make -k check-gcc RUNTESTFLAGS="sh.exp=pr59478.c --target_board=sh-sim \{-m2/-ml,-m2/-mb,-m2a/-mb,-m4/-ml,-m4/-mb,-m4a/-ml,-m4a/-mb}" Committed as r227958. Cheers, Oleg gcc/testsuite/ChangeLog: PR target/59478 * gcc.target/sh/pr59478.c: New.
