| # This file is crafted by hand on the basis of a very simple C program. |
| |
| # The original (NOT THIS FILE) error-triggering code is: |
| # #include "stdint.h" |
| # static volatile uint64_t g = 0; |
| # static const int32_t f() |
| # { |
| # uint32_t i; |
| # for (i = 0; (i != 10); i++) |
| # ++g; |
| # return 0; |
| # |
| # } |
| # |
| # int main() |
| # { |
| # f(); |
| # return 0; |
| # |
| # } |
| # When the above code is compiled by Clang 15.0.7 with -O1, it generates desired DW_OP_div for testing. |
| # Due to cross-platform issue, this case is hand-crafted for testing. |
