I consume the AST and do not rely on codegen.</div><div class=""><br class=""></div><div class="">I would love to be able to add some additional metadata to functions: specifically, the expected address of the function in the binary program. For instance:</div><div class=""><br class=""></div><div class="">int foo(int bar) __attribute__((address(0xdeadbeef)));</div><div class=""><br class=""></div><div class="">Attributes are especially convenient because they are easy to embed in a macro, which could end up looking like:</div><div class=""><br class=""></div><div class="">int foo(int bar) ADDRESS(0xdeadbeef);</div><div class=""><br class=""></div><div class="">Since this is an open-source project maintained by me only, I would prefer to not fork Clang, and just allow people to build my program with their distributions' stock Clang packages. Sadly, this apparently means that I can't use attributes for this purpose, because the valid attribute list appears to be hard-coded into Clang, and there doesn't seem to be any attribute that I can co-opt for this purpose.</div><div class=""><br class=""></div><div class="">Are there extension points that I can leverage in the Clang static libraries to allow this?<br class=""><div class="">
