aarch64: Add missing movmisalign patterns
The Advanced SIMD movmisalign patterns didn't handle 16-bit
FP modes, which meant that the vector loop for:
void
test (_Float16 *data)
{
_Pragma ("omp simd")
for (int i = 0; i < 8; ++i)
data[i] = 1.0;
}
would be versioned for alignment.
This was causing some new failures in aarch64/sve/single_5.c:
FAIL: gcc.target/aarch64/sve/single_5.c scan-assembler-not \\tb
FAIL: gcc.target/aarch64/sve/single_5.c scan-assembler-not \\tcmp
FAIL: gcc.target/aarch64/sve/single_5.c scan-assembler-times \\tstr\\tq[0-9]+, 10
but I didn't look into what changed from earlier releases.
Adding the missing modes removes some existing xfails.
gcc/
* config/aarch64/aarch64-simd.md (movmisalign<mode>): Extend from
VALL to VALL_F16.
gcc/testsuite/
* gcc.target/aarch64/sve/single_5.c: Remove some XFAILs.
