# 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.
