Hello, This is the same patch I posted in the PR. It seems to fix the issue. Tested on rev 192200 with make -k check RUNTESTFLAGS="--target_board=sh-sim \{-m2/-ml,-m2/-mb,-m2a/-mb,-m4/-ml,-m4/-mb,-m4a/-ml,-m4a/-mb}" and no new failures. OK? Cheers, Oleg gcc/ChangeLog: PR target/52480 * config/sh/sh.md (extv, extzv): Check that operands[3] is zero, regardless of the endianness. testsuite/ChangeLog: PR target/52480 * gcc.target/sh/sh4a-bitmovua.c: Compact skip-if list. Add runtime tests.
