10 years ago Hi, Yes, this is the right place for bugs. Thanks for the report. There is a lot of troubles with dependencies. I'll try to simplify processing and codegen for dependencies to make them reliable and faster.
Best regards,

The following code triggers an assertion failure:
void f(void) { double data[1][1];
long one = 1L; typedef double (*d_t)[one]; d_t r = data; #pragma omp task depend(out: r[0][0]) r[0][0] = 0.0;}
I believe the abort happens when the current token is the first '[' in the depend clause. The message is the following:

BTW, I could not find neither an openmp branch nor an openmp component in the main llvm bugzilla. So I hope this is the right place to submit the bug report.
