Bug ID: 47034
Summary: Loops with "# pragma clang loop interleave (enable)"
specified are vectorized even if -fno-vectorize is
specified
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Loop Optimizer
Assignee: unassignedb...@nondot.org
Reporter: fj876...@aa.jp.fujitsu.com
CC: llvm-bugs@lists.llvm.org
Loops with "# pragma clang loop interleave (enable)" specified are vectorized
even if -fno-vectorize is specified.
By the way, it is not interleaved. Is the movement as expected?
a.c
void foo(double * restrict a,
double * restrict b,
double * restrict c,
int n) {
#pragma clang loop interleave(enable)
for (int i=0;i<n;i++)
c[i] = a[i] + b[i];
return;
}
% clang -O1 -fno-vectorize a.c -Rpass=vectorize -S
a.c:7:3: remark: vectorized loop (vectorization width: 2, interleaved count: 1)
[-Rpass=loop-vectorize]
for (int i=0;i<n;i++)
