Here is the v7 patch which is changed to
/* Max number of bytes we can move from memory to memory in one
reasonably fast instruction, as opposed to MOVE_MAX_PIECES which
is the number of bytes at a time which we can move efficiently.
MOVE_MAX_PIECES defaults to MOVE_MAX. */
#define MOVE_MAX \
((TARGET_AVX512F && !TARGET_PREFER_AVX256) \
? 64 \
: ((TARGET_AVX \
&& !TARGET_PREFER_AVX128 \
&& !TARGET_AVX256_SPLIT_UNALIGNED_LOAD \
&& !TARGET_AVX256_SPLIT_UNALIGNED_STORE) \
? 32 \
: ((TARGET_SSE2 \
&& TARGET_SSE_UNALIGNED_LOAD_OPTIMAL \
&& TARGET_SSE_UNALIGNED_STORE_OPTIMAL) \
? 16 : UNITS_PER_WORD)))
OK for master? Thanks.
