Subject: [Bug c++/40751] G++ never packs typedef'd enums
Date: Tue, 14 Jul 2009 22:31:00 -0000	[thread overview]
Message-ID: <20090714223129.3496.qmail@sourceware.org> (raw)
In-Reply-To: <bug-40751-17949@http.gcc.gnu.org/bugzilla/>



------- Comment #2 from bryce dot schober at gmail dot com  2009-07-14 22:31 -------
I now see that the following syntax packs as expected:
typedef enum {
        ZERO = 0,
        ONE,
        TWO
} __attribute__ ((packed)) my_enum_t;

I have been unable to find a concise definition of how attributes are supposed
to be used with types in either the Type-Attributes or Attribute-Syntax
sections of the GCC manual. I guess this location for the attribute is a bit
more logical in the sense that the type isn't "complete" until the closing
brace.

It remains unclear whether both attribute locations are supposed to be
supported in both C and C++ or not. Either way, it's certainly not clear from
the docs.
