<pre>Hello,
LLVM always generate NEON vectors, but I want it generate SVE vectors. How can
I do this?
clang version 11.0.0
example.c:
#define ARRAYSIZE 1024
int a[ARRAYSIZE];
int b[ARRAYSIZE];
int c[ARRAYSIZE];
void subtract_arrays(int *restrict a, int *restrict b, int *restrict c)
{
for (int i = 0; i < ARRAYSIZE; i++)
{
a[i] = b[i] - c[i];
}
}
int main()
{
subtract_arrays(a, b, c);
}
command:
clang --target=aarch64-linux-gnu -march=armv8-a+sve -O3 -S example.c
Thanks</pre>
