John McCall	02ce2fe199	Make is_nonnull produce a primitive Builtin.Int1 instead ... of Bool, and use swift._getBool to turn that into a Bool as necessary. Swift SVN r7720	2013-08-29 06:47:15 +00:00

Anna Zaks	b67f3c3552	[SIL] Use the ReturnLocation/ImplicitReturnLocation instead of generic SILLocations. ... We mark the branch instructions leading into single epilog code with ReturnLocation/ImplicitReturnLocation. If SIL Gen simplifies the code and merges the code representing the return into the epilog block, the terminator of the epilog block (the ReturnInst) will have the return location info on it. Otherwise, the ReturnInst has the RegularLocation, which represents the enclosing FunctionExpr or Constructor/Destructor Decls. (I've discussed dropping the optimization from SILGen, and keeping the epilog code canonical, with Adrian; but he said that there might not be any wins in doing so, so keeping it for now.) Added AutoGeneratedLocation to represent segments of code generated by SILGen. This will be used for thunks and other auto-generated segments. Swift SVN r7634	2013-08-27 22:16:24 +00:00
Adrian Prantl	a1c6b653ad	Move DebugScopeStack from SILBuilder to SILGenFunction, using the swift new ... InsertedInstrs facility. No functionality change intended. Swift SVN r7520	2013-08-23 20:11:44 +00:00
Stephen Lin	8d90466523	Reorganize SIL source tree: move lib/SIL/SILGen -> lib/SILGen, move lib/SIL/Passes -> lib/SILPasses, add lib/SILPasses/Utils ... Swift SVN r7246	2013-08-14 23:47:29 +00:00
