------- Comment #9 from mmitchel at gcc dot gnu dot org 2007-02-26 20:19 ------- I'm sorry; I did apparently misunderstand. My reading of the report was that x did not become 2, and that this made the submitter unhappy.
I agree that x should not become 2. Although "2" is a valid *representation* of "true", converting "x" to "int" must yield "1", not "2". So, either we need conversion code, or we need to avoid "x" being "2" in the first place. The latter is clearly more efficient. Either the C++ front end or the middle end should transform any "++" operation on "bool" to "= true". I'm not sure if there are languages where the equivalent of "b = true; ++b" should yield "false". In any case, I suspect this is most easily done in the front end. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30274
