Bug #: 15021
Summary: LoopVectorizer does not vectorize reverse pointer
induction variables.
Product: libraries
Version: trunk
Platform: PC
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P
Component: Loop Optimizer
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
The LoopVectorizer does not vectorize the code below because it is a reverse
pointer induction variable. It should be pretty simple to implement.
void example1 (int *a, int n, int wsize) {
int m;
int *p = a;
do {
m = *--p;
*p = (m >= wsize ? m-wsize : 0);
} while (--n);
}
