In PR45212 comment 5 (https://bugs.llvm.org/show_bug.cgi?id=45212#c5), there is a reduced test case that failed after adding this patch. The assertion is from OMPChildren::getInnermostCapturedStmt.
Test case:
#include <cmath>
#include <omp.h>
#include <iostream>
class Myclass
{
public:
double A[10];
double B[10];
void add(int i)
{
for (int k = 0; k < 10; k++) {
#pragma omp atomic
B[k] += A[i];
}
}
};
int main(int argc, char* argv[]){
Myclass foo;
for (int i = 0; i < 10; i++) {
foo.A[i] = i;
foo.B[i] = 0;
}
#pragma omp target teams distribute parallel for
for (int i = 0; i < 10; i++) {
foo.add(i);
}
printf("Correctness check: B[2]= %f \n",foo.B[2]);
return 0;
}
Backtrace:
Assertion failed: (isa<X>(Val) && "cast<Ty>() argument of incompatible type!"), function cast, file /Users/cchen/workspace/llvm-project/llvm/include/llvm/Support/Casting.h, line 269.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace, preprocessed source, and associated run script.
