Does anyone know: Of the patches that Apple made to GCC 4.2, how many are localized to Object= ive-C, Objective-C++, C, and C++ front-ends? (These would not affect linki= ng Clang/LLVM-compiled code to GNAT-compiled libraries, other than the auto= mated binding generation from C, which can be avoided for the time being.) = (Again, the focus here is linking Clang/LLVM-compiled Objective-C[++] obje= ct-files for UI layers of an app to GNAT-compiled object-files for nonUI la= yers of an app.) Of the patches that Apple made to GCC 4.2, how many were to the back-end? = Of those, how many were never pulled forward (or ported) to the mainline of= GCC 4.3 and later? Of those, how many were affecting only Intel-based Mac= proper, not the cross-compilation to ARM devices? I suspect that this na= rrowing of focus results in drastically fewer ARM-iOS patches that either n= ever showed up in GCC 4.9 or that have undergone software-rot due to infreq= uent use/maintenance since Apple switched to Clang/LLVM. Mac(-proper) developers for Intel processors who use the GCC 4.8 & 4.9 GNAT= compiler (but who do not develop in GNAT for ARM-based devices) should hav= e some feel for the stability of the drastically-post-4.2 GCC compiler rele= ases for all the patches other than the ones specifically for arm-apple-dar= win. Any insights on these non-ARM patches, GNAT users on Intel-based Mac:= are drastically-post-4.2 GCC releases (especially GNAT releases) stable f= or Ada-on-Mac development?
