URL: https://github.com/llvm/llvm-project/commit/87d4ea2433663b4aabe9c979a4dd47ef6adedc8b DIFF: https://github.com/llvm/llvm-project/commit/87d4ea2433663b4aabe9c979a4dd47ef6adedc8b.diff LOG: [gn build] Make an explicit `use_lld = true` on mac use lld.darwinnew use_lld defaults to true on non-mac if clang_base_path is set (i.e. the host compiler is a locally-built clang). On mac, the lld Mach-O port used to be unusable, but ld64.lld.darwinnew is close to usable. When explicitly setting `use_lld = true` in a GN build on a mac host, check-lld passes, two check-clang tests fail, and a handful check-llvm tests fail (the latter all due to -flat_namespace not yet being implemented).
