search for: __hash

Hi, Libc++ has been shipping the <ext/hash_set>, <ext/hash_map> and <ext/__hash> headers for a while and they are deprecated. Those headers contain data structures like __gnu_cxx::hash_map that have replacements like std::unordered_map. I would like to remove those headers. I've put up a patch for review but I won't commit it until we have a sort of plan because I k...

The following patches shave some rough edges off the tools build system to allow cross compiling for at least arm32 and arm64 based on the Debian/Ubuntu multiarch infrastructure. They also add the necessary fixes to build for arm64 (which I have only tried cross, not native). I have posted some instructions on how to compile with these patches on the wiki:
