Michael Gottesman	3ba6b7c663	[sil-combine] Make output of (extract (load)) -> (load (element_addr)) deterministic by not using pointer address as a sorting criteria for vardecls. ... Instead for vardecls, we use the index of the field in the structdecl itself as a stable ordering of vardecls. I validated that the indeterminism was gone by running the failing test 1000 times in a row. Doug and I were hitting the indeterminism with well less than 100 iterations before, so I feel the number of iterations is sufficient. Swift SVN r13859	2014-02-13 04:57:54 +00:00
Michael Gottesman	de48699d49	[sil-aa] Teach SILAA how to prove that two GEPs from the same base pointer with the same projections must alias. ... Swift SVN r13768	2014-02-11 00:55:09 +00:00
Michael Gottesman	3a1d46d145	[sil-code-motion] Refactor out the address projection path computation from findExtractPathBetweenValues to a new function findAddressProjectionPathBetweenValues and wire up the old method to use the results of the refactored method. ... This is in preparation for using the refactored functionality in Alias Analysis's address projection disambiguation code. Swift SVN r13765	2014-02-11 00:09:15 +00:00
Michael Gottesman	5b3423308d	Refactor out the class Projection class into its own header swift/SIL/Projection.h. ... This class allows you to deal with tuple and nominal projections in a way that is agnostic of either of them. Expect some incoming utilities based off of this for dealing with what I call 'aggregate type trees'. Swift SVN r13735	2014-02-10 05:07:36 +00:00
