Many desktop environments/toolkits expect some sort of accelerati= on anymore (even if you don't think it does), and LLVMpipe and the like provide that software rendering. > (Besides I'm kind of puzzled why we don't simply use the base system's LL= VM > which for 12-STABLE and above is already LLVM80. Maybe just my lack of > understanding.) -RELEASEs don't change the toolchain originally available upon release, so = for 12.0-RELEASE, LLVM is fixed at 6.0.0. Besides, the base system LLVM is buil= t as static libraries and binaries, and some LLVM components not needed/useful to build the base system are stripped away. Think, the base system uses a comp= iler toolchain *based on LLVM*, in the same way that the base system GCC isn't vanilla either.
