Re: [PATCH 0/6] Convert gimple to a C++ class hierarchy

cessing all of it (i.e. every GTY-ed class declaration), and have our gengtype successor plugin emit appropriate #if in the generated C++ code. Of course having gengtype replaced by a plugin requires such a plugin to be developed and GCC maintainers to have access to some gcc... Cheers -- Bas

Re: Questions about LTO infrastructure and pragma omp target

e plugins are mentioned (and I guess Jakub was talking of linker plugins) I would add that GCC plugins might want to add (and later use) their own arbitrary LTO data in these sections. Cheers -- Basile STARYNKEVITCH http://starynkevitch.net/Basile/ email: basilestarynkevitchnet mobile: +

libbacktrace & plugins....

inside plugins (at least those compiled with -g). Is is reasonably feasible? I'm not familiar with libbacktrace, but (since MELT would be very happy with that) I might perhaps help Cheers. -- Basile STARYNKEVITCH http://starynkevitch.net/Basile/ email: basilestarynkevitchnet m

Re: -Og changes on 4.7.3?

personal use it is so much simpler to just build GCC 4.8 and use it. No good reason to stick to a patched GCC 4.7 Cheers. -- Basile STARYNKEVITCH http://starynkevitch.net/Basile/ email: basilestarynkevitchnet mobile: +33 6 8501 2359 8, rue de la Faiencerie, 92340 Bourg La Reine, France *** opin

Re: Simple way to pass new #pragma to GIMPLE

Re: Obtaining a callsite address.

ly do you mean by "callsite"). However, the called function can be obtained by gimple_call_fndecl which gives a tree. If using MELT http://gcc-melt.org/ you just use a gimple_call pattern... Regards. -- Basile STARYNKEVITCH http://starynkevitch.net/Basile/ email: basilestaryn
