X-Git-Tag: upstream/3.4.2~49
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d271dbe0a8b230e566fa3385babdc9cc0ca214ea;p=platform%2Fupstream%2Flibffi.git

Add some missing #if conditionals from Apple's code drop (#620)

* arm/aarch64: Add FFI_CLOSURES conditionals where appropriate

Signed-off-by: Jeremy Huddleston Sequoia <jeremyhu@apple.com>
