I only tested this with Project Loon's avionics firmware which freed up ~1.2% of ROM space. A small amount, but for us every bit counts. I did look at creating a templated wrapper class instead which uses placement-new to construct the wrapped type in a private char buffer. This results in the same effect as this patch (no dtor references are emitted). The only issue is the code is a big uglier to read, and we might forgot to use the wrapper (though a static checker could be added for this case). I figured it'd be best to add compiler support so other C++ based firmware projects can benefit as well. https://reviews.llvm.org/D35338 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
