PR c++/53528 C++11 attribute support
This patch implements the c++-11 generalized attributes, described in
the N2761 paper[1].
The idea is to modify the front-end to accept the new attribute syntax
(including alignas expressions) and to build an internal
representation similar to the one we already have for GNU attributes.
This lets us re-use our existing GNU attribute mechanisms to support
the generalized c++11 attributes.
The patch does change the existing internal representation to support
scoped attribute (aka attributes with namespaces), which is a concept
that doesn't exist in GNU attributes. I have thus put all existing
GNU extension attributes into the "gnu" namespace. For instance, in
C++-11, the "unused" attribute would be represented as
"[[gnu::unused]]". Because there is no syntax for scoped attributes
in C, writting "__attribute__((unused))" unconditionnally refers to
the "unused" attribute in the "gnu" namespace.
Note that this patch follows a conservative understanding of the
specification by disallowing attributes appertaining to types, unless
they apply to a type definition.
Tested on x86_64-unknown-linux-gnu and powerpc64-unknown-linux-gnu.

PR c++/53528 C++11 attribute support
This patch implements the c++-11 generalized attributes, described in
the N2761 paper[1].
The idea is to modify the front-end to accept the new attribute syntax
(including alignas expressions) and to build an internal
representation similar to the one we already have for GNU attributes.
This lets us re-use our existing GNU attribute mechanisms to support
the generalized c++11 attributes.
The patch does change the existing internal representation to support
scoped attribute (aka attributes with namespaces), which is a concept
that doesn't exist in GNU attributes. I have thus put all existing
GNU extension attributes into the "gnu" namespace. For instance, in
C++-11, the "unused" attribute would be represented as
"[[gnu::unused]]". Because there is no syntax for scoped attributes
in C, writting "__attribute__((unused))" unconditionnally refers to
the "unused" attribute in the "gnu" namespace.
Note that this patch follows a conservative understanding of the
specification by disallowing attributes appertaining to types, unless
they apply to a type definition.
Tested on x86_64-unknown-linux-gnu and powerpc64-unknown-linux-gnu.
