Hi, playing around a little bit, reading into this nice codebase of LLVM/clang and talking to Matthias. Concerned with this horrible state of gccxml -- no offense -- but it does not make sense to force it to cross-compile if it is going to be replaced sooner than later. So:
What does a replacement for gccxml in typelib have to provide: - the full qualifying names of all types defined in a given set of header-files - their memory layout: offset+type of all members, the sizeof the type itself right? Nice would be: - bail out if types use too fancy features, like virtual functions or dynamic members (except some whitelisted special cases) The proof-of-concept-level stuff I have so far is living in $WIESE/temp/mzenzes/clang-typelib.bare but it would make more sense to push it out into the internet -- should i use my private github account for things like this? -- The second point can be done using "clang -fdump-record-layouts" (see http://lists.cs.uiuc.edu/pipermail/cfe-dev/2014-July/037778.html. It results in an output like this: 0 | struct base::JointState 0 | double position 8 | float speed 12 | float effort 16 | float raw | [sizeof=24, dsize=20, align=8 | nvsize=20, nvalign=8] for the first point (and third) "clang-check -ast-list" could be used -- but it prints too much. So a small clang-tool with added filtering might come in handy? Greetings Martin -- M.Sc.
