Re: [C++/Obj-C++ PATCH] Fix Objective-C++ breakage

Is that a good thing? I've done little middle-end work, so I don't have much experience with this. How often does a change to the optimizers pass all of the C/C++ testsuites, but fail in the Java or Fortran testsuites?


These aren't rhetorical questions; I have no idea. I'm interested in what actual experience is like here. My guess would be that changes to the build machinery are quite likely to break various languages, but that changes to (say) the register allocator are unlikely to work reliably in C/C++, but not in Fortran/Java. And, that, in fact, Ada is the language other than C/C++ most likely to show up problems.
