[Bug c/40172] [4.5 Regression] Revision 147596 breaks bootstrap

Tue May 19 20:29:00 GMT 2009

------- Comment #26 from manu at gcc dot gnu dot org  2009-05-19 20:29 -------
The case in toplev.c cannot be fixed without tracking macro expansions somehow,
but I wonder why it warns (multiple times!) for this case:

> ../../trunk/gcc/config/mips/sb1.md:159: error: logical Ã¯Â¿Â½orÃ¯Â¿Â½ of collectively
> exhaustive tests is always true
> ../../trunk/gcc/config/mips/sb1.md:159: error: logical Ã¯Â¿Â½orÃ¯Â¿Â½ of collectively
> exhaustive tests is always true
> ../../trunk/gcc/config/mips/sb1.md:159: error: logical Ã¯Â¿Â½orÃ¯Â¿Â½ of collectively
> exhaustive tests is always true
> ../../trunk/gcc/config/mips/sb1.md:159: error: logical Ã¯Â¿Â½orÃ¯Â¿Â½ of collectively
> exhaustive tests is always true

David, could you produce a testcase?

Anyway, moved out of Wextra, so bootstrap should be fixed now.
