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
}

Notes
(0001557) virgile (developer) 2011-03-08 10:33	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.

(0001561) signoles (manager) 2011-03-08 11:08	In the same way, in the example below "x" is promoted to integer bug not "(int)z". Quite strange. /@ assert x == (int) z; /
