| #include <stdio.h> |
| |
| // Given the following overloaded function definitions |
| |
| void ovf(unsigned long, short, short) { printf ("PASS\n"); } |
| void ovf( int, short, unsigned long) { printf ("FAIL\n"); } |
| |
| // and the call |
| // |
| // ovf(unsigned long, unsigned int, unsigned int) |
| // |
| // it seems to me (and to cfront) that this should resolve to ovf #1 above, |
| // but g++ resolves it to ovf #2. Resolving to ovf #1 requires two conversions |
| // (unsigned int => short) while resolving to ovf #2 takes two conversions |
| // (unsigned long => int, unsigned int => short) and a promotion |
| // (unsigned int => unsigned long). |
| |
| int main(int, char**) |
| { |
| unsigned long pixmap = 0; |
| unsigned int x = 0; |
| unsigned int y = 0; |
| |
| ovf(pixmap, x, y); |
| return 0; |
| } |
