Add frozen_string_literal to all files. 2019-04-19 15:38:03 +09:00			`# frozen_string_literal: true`

hardware: use Nehalem flags on >= Sierra. See https://en.wikipedia.org/wiki/MacOS_Sierra#System_requirements. 2018-12-20 20:10:54 +00:00			`module Hardware`
version: add CPU tests. Add a new API inspired by discussion in https://github.com/Homebrew/homebrew-core/pull/36435 to query if a given CPU option is supported by a version of macOS. 2019-01-28 19:31:21 +00:00			`def self.oldest_cpu(version = MacOS.version)`
Make `Hardware.oldest_cpu` depend on architecture Starting with Xcode 12 Beta 2, builds that used to work on Apple Silicon now break due to `Hardware#oldest_cpu` returning `:nehalem` [1]. This commit is the first in a series of improvements to `Hardware#oldest_cpu`. It resolves the Xcode 12 Beta 2 issue for now.
