Hi all, Can someone explains to me what these gcc warnings mean? comparison of distinct pointer types lacks a cast large integer implicitly truncated to unsigned type overflow in implicit constant conversionI keep getting these warning when I use gcc to compile the test codes. Thanks, Bill -------- Original Message --------
Hi all, I created testsuites with different levels of max_expr_depth. I compiled these files with gcc, and got the following warnings. comparison of distinct pointer types lacks a cast large integer implicitly truncated to unsigned type overflow in implicit constant conversion Attached is one of the 7 sets of test codes created. If anyone is interested in all of them, i can post them all later. -Bill |
