This means that to + be able to successfully build the cross-tools stage of buildworld, with + clang as the bootstrap compiler, your system compiler or cross compiler + should either be clang 3.3 or later, or gcc 4.8 or later, and your + system C++ library should be libc++, or libdstdc++ from gcc 4.8 or + later. + + On any standard FreeBSD 10.x or 11.x installation, where clang and + libc++ are on by default (that is, on x86 or arm), this should work out + of the box. + + On 9.x installations where clang is enabled by default, e.g. on x86 and + powerpc, libc++ will not be enabled by default, so libc++ should be + built (with clang) and installed first. If both clang and libc++ are + missing, build clang first, then use it to build libc++. + + On 8.x and earlier installations, upgrade to 9.x first, and then follow + the instructions for 9.x above. + + Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by + default, and do not build clang. + + Many embedded systems are resource constrained, and will not be able to + build clang in a reasonable time, or in some cases at all. In those + cases, cross building bootable systems on amd64 is a workaround. + + This new version of clang introduces a number of new warnings, of which + the following are most likely to appear: + + -Wabsolute-value + + This warns in two cases, for both C and C++: + * When the code is trying to take the absolute value of an unsigned + quantity, which is effectively a no-op, and almost never what was + intended. The code should be fixed, if at all possible. If you are + sure that the unsigned quantity can be safely cast to signed, without + loss of information or undefined behavior, you can add an explicit + cast, or disable the warning. + + * When the code is trying to take an absolute value, but the called + abs() variant is for the wrong type, which can lead to truncation. + If you want to disable the warning instead of fixing the code, please + make sure that truncation will not occur, or it might lead to unwanted + side-effects. + + -Wtautological-undefined-compare and + -Wundefined-bool-conversion + + These warn when C++ code is trying to compare 'this' against NULL, while + 'this' should never be NULL in well-defined C++ code. However, there is + some legacy (pre C++11) code out there, which actively abuses this + feature, which was less strictly defined in previous C++ versions. + + Squid and openjdk do this, for example. The warning can be turned off + for C++98 and earlier, but compiling the code in C++11 mode might result + in unexpected behavior; for example, the parts of the program that are + unreachable could be optimized away. + +20141222: + The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) + kernel sources have been removed. The .h files remain, since some + utilities include them. This will need to be fixed later. + If "mount -t oldnfs ..." is attempted, it will fail. + If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, + the utilities will report errors. + +20141121: + The handling of LOCAL_LIB_DIRS has been altered to skip addition of + directories to top level SUBDIR variable when their parent + directory is included in LOCAL_DIRS.
