Steps to reproduce JIT memory errors
make wlvlang-jit PYPYPATH=~path/to/pypy
# This should pass
make test_all_jit
# Unfortunately the path to the script needs to be relative! (I should fix that)
bin/wlvlang-jit tests/benchmarks/thread-ring.wl 10 10
# This should cause a segfault or:

auto-vectorisation example in GCC
void test_vec(double* restrict a, double* restrict b) {
int i;
double *x = __builtin_assume_aligned(a, 16);
double *y = __builtin_assume_aligned(b, 16);
for(i = 0; i < SIZE; i++) {
x[i] = x[i] + y[i];
}
}

Get the current Python path as a string with correct path separator
import sys
import os
def pythonpath():
# Remove filter if you don't care about cases such as: ':/path::', where members of the path are
# empty. It would be slightly faster to complete this operation if the filter was not run but the size of the
# input is likely to be small
os.pathsep.join(filter(lambda path: len(path) > 0, sys.path))
