--- Comment #21 from Stas Sergeev <stsp at users dot sourceforge.net> --- (In reply to Jakub Jelinek from comment #19) > It is just that clang doesn't support -g3 at all, as can be seen by clang > not producing any .debug_macinfo nor .debug_macro sections. So with -fdebug-macro it actually produces .debug_macinfo, but still no .debug_macro. Yet gdb is quite happy with that and can see the macros. So... Why "clang -g3 -fdebug-macro -E -Wp,-P - </dev/null" doesn't produce anything on screen?? So it works perfectly! But I don't know how. :)
