Bug ID: 119480
Summary: Wrong code generated in simple program that uses
LLVM::map_to_vector
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: Mark_B53 at yahoo dot com
Target Milestone: ---
#include <llvm/ADT/SmallVectorExtras.h>
int main()
{
int data[] = {1,2,3,4,5};
bool changed = false;
auto fn = [&](int val) { changed = true; return val; };
auto out = llvm::map_to_vector(data, fn);
return changed;
}
Program should print 1. However, on GCC 12.* and 13.* for -O1 & -O2, the
output is 0.
// Summary of Results
// -O0 -O1/2 -O3
// 11.* pass pass pass
// 12.* pass FAIL pass
// 13.* pass FAIL pass
// 14.* pass pass pass
