Graham Batty	0aaf9af5c9	Use a type_traits shim for is_trivially_constructible. ... Swift SVN r23383	2014-11-17 21:23:20 +00:00
Graham Batty	243fb6de51	Don't do is_trivial_constrictible on libstdc++. ... This is currently unimplemented as of this macro being 20141011, when it is implemented in libstdc++ the check should be changed to a < the version that implemented it. Swift SVN r23368	2014-11-17 17:15:11 +00:00
Joe Groff	b9bd3a2fea	Ensure HeapObject and RefCount objects are trivially constructible and destructible. ... We don't want them to trigger .cxx_*struct behavior in our ObjC base classes after Clang is fixed. Swift SVN r23332	2014-11-14 21:54:48 +00:00
Greg Parker	c6a88262cf	[stdlib] Scrap bit-rotted FastEntryPoints.s. Rewrite refcounts using __atomic. ... Generated code on x86_64 for swift_retain and swift_release and swift_allocObject are unchanged. arm64 is improved by using weaker memory barriers, fixing rdar://17423624.

Dave Abrahams	d016db3285	[stdlib] Factor common non-ObjC instance members ... Make sure that if the object layout changes, we don't have to update the stdlib in too many places. Swift SVN r15166	2014-03-17 23:12:18 +00:00
Dave Abrahams	6eee8e3205	Move HeapObject into the stdlib shim module ... Now that we can read definitions directly from "C" headers, stop trying to maintain a mirror of the HeapObject struct in Swift code in the standard library. Swift SVN r14982	2014-03-12 23:48:31 +00:00
