[cfe-dev] Custom pragmas in Clang

[Tarun Prabhu via cfe-dev]

Hi,

I am trying to enable some source-to-source transformations which are
enabled using pragmas. I mostly just want insert calls to a library
whenever I encounter a pragma. For example something like this

> #pragma callout
> x = foo();

would become:

> mylibrary::callout();
> x = foo();

Is it possible to implement something like this as a Clang plugin or using
the libtooling interface? I know how to hijack documentation comments to
make this possible, but I would prefer to use a pragma. I would rather
avoid modifying clang itself to enable this.

Thanks,

Tarun
