Hello All, References: http://gcc.gnu.org/ml/gcc-patches/2010-11/msg02562.html http://gcc.gnu.org/ml/gcc-patches/2010-11/msg02565.html
As you know, gengtype is becoming a user visible program [it is needed to people coding GCC plugins which uses GTY], probably to be installed in the same directory as cc1 (this is what Alexander Oliva told me at last GCC summit). So it should be installed there. And the gtype.state file should also be installed somewhere. It is an internal textual file which summarizes all the information gotten by gengtype when parsing all GCC GTY-ing headers. This state file is required for generating gt-plugin.h files by gengtype from a user plugin.c (etc...). I am not familiar enough with GCC build system (this part of GCC still scares me a lot), and even with the help I've gotten so far, I am not able to do that alone. I suspect the gcc/Makefile.in changes are tiny (perhaps less than a dozen lines), but I cannot guess them reliably (notably because I am not familiar enough with the build vs host vs target installations). From what I understood eg in http://gcc.gnu.org/ml/gcc-patches/2010-11/msg02571.html gengtype might need to be compiled twice, once in build mode and once in host mode, but I don't understand the details. Likewise, I believe we should have tests of gengtype, at least in plugin mode. While I could "specify" them (e.g. saying that with such testinput.c file gengtype should generate such gt-testinput.h file with such and such regexp patterns) I am not familiar enough with dejagnu to implement any kind og such things. Again, I would imagine that for dejagnu knowing people, it is almost trivial. Once a dejagnu test infrastructure is provided, coding test cases is simple. And it very probably will be useful for the required extensions of gengtype (like supporting C++ GTY-ed classes). Could anyone please help, either by a *detailed* explanation or by a simple patch (I would imagine that doing the patch is simpler than explaining things...) It would be sad if gengtype won't be installed in the 4.6 release? Or should I open a PR about that?
