If this is an option to consider than runtime check > android_get_device_api_level() < 30 can be replaced by `__ANDROID_API__ < 30` depends what you mean... in 10 years or so, yes, no-one is likely to still care about the older API levels and we can just delete this. but until then, no, there's _one_ copy of compiler-rt that everyone uses, and although _OS developers_ don't need to support anything more than a couple of years old, most app developers are targeting far lower API levels than that (to maximize the number of possible customers). TL;DR: "you could add that condition to the `#if`, but no-one would use it for a decade". (and i think the comment and `if` below should make it clear enough to future archeologists when this code block can be removed :-) ) Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D158641/new/ https://reviews.llvm.org/D158641 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
