(our seccomp policies also mean "good luck trying to run a static musl/glibc binary".) clang's Android target already assumes bionic in other ways --- things like whether math functions set errno, or whatever, so this seems in keeping to me. ah, you don't mean *printf* implementations, you mean "other functions that take printf arguments"? yeah, that's a more interesting case. though that one's already broken: there's already no way to say what subset of printf formats you do/don't support. (all the ones in the Android OS itself are all subsets of the bionic printf; many equal, but several *much* smaller. that would be a pretty cool thing to be able to specify, but that's a much bigger bug, and this change brings us closer to reality than we currently are, for the 99% case :-) ) Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D117611/new/ https://reviews.llvm.org/D117611 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
