Support for `__attribute__((gccxml(#x)))`? about castxml

[bradking]

I've edited the issue subject line to clarify that this is about the gccxml(...) attribute rather than dllexport markup. The latter is supported.

Unfortunately CastXML is not able to support the arbitrary gccxml(...) attributes. This is because Clang represents each supported attribute with dedicated source structures, so additional attributes cannot be handled. One can see this in the Clang source tree where the attributes are declared in the include/clang/Basic/Attr.td file.

One might be able to use the annotate attribute instead. It appears to accept a string as an argument. I have not tried it though.

annotate attribute looks exactly what I'm looking for, thanks for pointing this out. I will give it a try

[bradking]

Great. I have some local changes to include the annotate(...) attribute in the attributes="" XML element attribute just like gccxml did with gccxml(...). It still needs more testing before I push it out though.

I've implemented support for annotate(...) in commit e73fba5.

Oh, that's cool, thanks!

I just made a PR to add annotation to function arguments. This was also allowed in gccxml so I guess we can implement it in castxml: #26
