Joe Groff	e3f9a2035c	SIL: Move SILGen and passes over to use "builtin" instead of "apply (builtin_function_ref)". ... Swift SVN r22785	2014-10-15 23:37:22 +00:00
Jordan Rose	3fcdfd40e9	Remove the "swift/Basic/Optional.h" header. ... llvm::Optional lives in "llvm/ADT/Optional.h". Like Clang, we can get Optional in the 'swift' namespace by including "swift/Basic/LLVM.h". We're now fully switched over to llvm::Optional! Swift SVN r22477	2014-10-02 18:51:45 +00:00
Roman Levenstein	a81a99776f	Improve optimization of builtin operations that may overflow. Remove overflow checks if it can be proven that no overflow can happen. ... Swift SVN r21874	2014-09-11 16:00:54 +00:00
Roman Levenstein	933e4bff17	[sil-simplify] Peepholes for (trunc (s_to_u (zext x)))->x and (trunc (u_to_s (zext (lshr x 1) Word -> Int64)) Int64 -> Word) -> (lshr x 1). ... Related to rdar://17433082 and rdar://17406327 Swift SVN r21700	2014-09-04 10:27:08 +00:00
Michael Gottesman	75d8e4d748	[sil-combine] Move isZeroValue out of SILCombine and into ValueTracking. ... Swift SVN r21540	2014-08-28 21:27:53 +00:00
Michael Gottesman	b04b14e0fa	Refactor isNonEscapingLocalObject/getUnderlying object into their own file ValueTracking.cpp. ... This is because I need them in ARCAnalysis.cpp and from a modeling perspective it is no longer just going to be used just in AA since they are of larger functionality.
