Hi All,
The following patch has been bootstrapped and regtested on powerpc64le-linux and powerpc64-linux. The vec_extractm testcase assumes little-endian ordering when checking the expected result. On big-endian targets, the vector layout differs causing the char and word tests to fail. Use endian-dependent expected values for the char and word tests. Also use an result and expected_result variable consistently for all vec_extractm tests and remove unused variables. 2026-09-02 Jeevitha Palanisamy <[email protected]> gcc/testsuite/ PR target/127148 * gcc.target/powerpc/vsx_mask-extract-runnable.c: Fix expected results for vec_extractm on big-endian targets.
