Subject: lib,src: make os.endianness() inlinable
X-Git-Tag: v1.0.0~281
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=355b96b605592d753f7381709e4827fa2e5ee29d;p=platform%2Fupstream%2Fnodejs.git

lib,src: make os.endianness() inlinable

Turn os.endianness() from a run-time function into a pure JS function.
Upsides: makes it a good candidate for inlining at the call site.
Downsides: none that I can think of.
