Adding -mmove-max=128 and -mstore-max=128 to the dg-options of the recently added gcc.target/i386/pieces-memcmp-2.c avoids changing the intent of this testcase when adding -march=cascadelake to RUNTESTFLAGS. Tested on x86_64-pc-linux-gnu. Committed as obvious.
2023-06-29 Roger Sayle <ro...@nextmovesoftware.com> gcc/testsuite/ChangeLog * gcc.target/i386/pieces-memcmp-2.c: Specify that 128-bit comparisons are desired, to see if 256-bit instructions are generated inappropriately (fixes test on -march=cascadelake).
