Hi, indeed it does:
test@sve-1:~/temp$ ./gcc/bin/gcc -march=armv8-a+sve -O3 -msve-vector-bits=256
sve.c -o sve.exe
test@sve-1:~/temp$ ./sve.exe
test@sve-1:~/temp$ ./gcc/bin/gcc -march=armv8-a+sve -O3 -msve-vector-bits=256
-fno-vect-cost-model sve.c -o sve-no-cost.exe
test@sve-1:~/temp$ ./sve-no-cost.exe
sve-no-cost.exe: sve.c:46: main: Assertion `dest_int16_t_int8_t[i * 2] ==
(src_int16_t_int8_t [index_int16_t_int8_t[i * 2]] + 1)' failed.
Aborted (core dumped)
I have noticed some other gather related failures but haven't had time to
triage them to file bugs. Hoping to get to that soon.
