Subject: [patch gimplify]: Fix for PR/48984
Date: Fri, 13 May 2011 09:23:00 -0000	[thread overview]
Message-ID: <BANLkTinEMSM2yQ85BwiM2FJSeu1+xe=DVg@mail.gmail.com> (raw)

Hello,

this patch fixes the issue reported in PR/48984.  Issue is that
fortran has multiple BOOLEAN_TYPE'ed types with different modes. So
the check for BOOLEAN_TYPE in gimplification is wrong and instead we
need to check for identify to boolean_type_node.

ChangeLog

2011-05-13  Kai Tietz

        * gimplify.c (gimplify_expr): Check for boolean_type_node instead
        for BOOLEAN_TYPE for TRUTH-NOT/AND/OR/XOR.
        (gimple_boolify): Check for cast for boolean_type_node instead for
        BOOLEAN_TYPE.

Bootstrap passed and now doing fortran testsuite run to verify.

Regards,
Kai
