Joe Groff	7d274e28a7	SIL: Add an unchecked_addr_cast instruction. ... Cast an address to another address type without the silly address_to_pointer/pointer_to_address round trip. Swift SVN r16743	2014-04-24 04:14:48 +00:00
Joe Groff	68f942117a	SIL: Squash 'ref_to_native_object' and 'native_object_to_ref' into one 'unchecked_ref_cast' insn. ... An unsafe cast from a base to a derived class isn't really all that different from one from Builtin.NativeObject to an arbitrary class, so relax this pair of instructions to allow an arbitrary bitcast. This only combines the instructions; it doesn't attempt to simplify any codegen that was emitting round-trip casts before yet. Swift SVN r16736	2014-04-24 03:10:53 +00:00
John McCall	8681963bcb	A couple of long-overdue renames. ... Builtin.ObjectPointer -> Builtin.NativeObject Builtin.ObjCPointer -> Builtin.UnknownObject Swift SVN r16634	2014-04-22 00:17:08 +00:00
Mark Lacey	679077305f	Revert "Assert rather than going into an infinite loop." ... This reverts r16307, which is not really useful with r16303 in place. Swift SVN r16336	2014-04-14 22:13:18 +00:00
Mark Lacey	570a158679	Assert rather than going into an infinite loop. ... Swift SVN r16307	2014-04-14 07:57:39 +00:00
Joe Groff	855ea99063	SIL: Combine 'archetype_ref_to_super' and 'upcast'. ... We were wantonly applying 'upcast' to archetypes in some cases, and really, that's OK, since these instructions do the same thing (and generic specialization could turn archetype_ref_to_super into upcast). Make everyone's life easier by folding archetype_to_super into upcast. Fixes <rdar://problem/16192324>. Swift SVN r14496	2014-02-28 04:33:18 +00:00
Michael Gottesman	0f287562de	There are more than a few methods in SIL.cpp for SILValue. Refactor SILValue's implementations into its own file SILValue.cpp. ... Swift SVN r13445	2014-02-04 20:25:49 +00:00
