------- Comment #30 from pinskia at gcc dot gnu dot org 2007-05-02 17:10 -------
Only one suggestion for the patch, instead of:
- if (is_gimple_cast (t) || TREE_CODE (t) == VIEW_CONVERT_EXPR)
+ if (is_gimple_cast (t) || TREE_CODE (t) == VIEW_CONVERT_EXPR
+ || TREE_CODE (t) == ALIASING_CONVERT_EXPR)
Shouldn't ALIASING_CONVERT_EXPR be considered a gimple cast? Yes you might
need to change some places which use is_gimple_cast but it seems like a better
idea to treat it as a cast rather than anything else.
