https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=240507 --- Comment #3 from Kyle Evans <kevans@freebsd.org> --- (In reply to Dimitry Andric from comment #2) > The problem with that is that a lot of unused targets will be built, which is why the MK_LLVM_TARGET_ knobs were created in the first place. Ideally, only the minimum set of targets is built. Right... so this all feels like a good opportunity for foot shooting. =\ It'd be nice if we had some way of listing the targets that `cc` supports, so we can decide if we need to bootstrap a cross-compiler that works for what we're trying to build and we can at least force *that* option on for the bootstrap compiler. The last time I checked, one could turn off all of the LLVM_TARGET_* knobs except, say, LLVM_TARGET_X86. They install a machine that way, and the machine has all of the knobs except LLVM_TARGET_X86 turned off just like the builder. A cross-build of aarch64 would then just error out with 'target triple unknown' or something to this effect, rather than being able to detect- "oh yes, the host isn't functional for this." -- You are receiving this mail because: You are the assignee for the bug.help
