# Test handling of values represented via DW_OP_div

# RUN: %clang --target=x86_64-pc-linux -o %t %s
# RUN: %lldb %t -o "b f" -o "r" -o "c" -o "c" -o "expression -T -- i" \
# RUN: -o "exit" | FileCheck %s

# Failing case was:
# (uint32_t) $0 = 0
# CHECK: (uint32_t) $0 = 2

# This case is generated from the following code:
# #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;
#
# }
