Bug ID: 51666
Summary: -Wsign-compare complains on #pragma omp taskloop
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: OpenMP
Assignee: unassignedclangb...@nondot.org
Reporter: lebedev...@gmail.com
CC: llvm-bugs@lists.llvm.org

void callee(int);
void entry(int width) {
#pragma omp taskloop
for(int i = 0; i < width; ++i)
callee(i);
}
<source>:5:5: warning: comparison of integers of different signs: 'unsigned
long' and 'int' [-Wsign-compare]
for(int i = 0; i < width; ++i)
~~~ ^~~
1 warning generated.
Compiler returned:
There is no `unsigned long` in the source code, but presumably
there is something OMP-internal there.
I don't see why this is being diagnosed,
nor am i seeing how to nicely workaround that.
