| Summary | 0000744: Too much type promotion for terms | ||||||||
| Description | on the above example, C typing rules should apply. Thus no logic term should be logic integer. Unfortunately, in the current implementation, all of them are integer. void main(void) { int x = 0, y = 0; long z = 0L; /*@ assert x == y; */ // x and y are promoted to integer; should be promoted to int instead /*@ assert x == z; */ // x and z are promoted to integer. x should be promoted to long instead } | ||||||||

Agreed for the comparison between x and y as they are both int. For the comparison between x and z, they have distinct type and are both promoted to integer. The user still can cast x to long if ey want to do the comparison at this level. |

In the same way, in the example below "x" is promoted to integer bug not "(int)z". Quite strange. /*@ assert x == (int) z; */ |

Fix committed to stable/neon branch. |
