Chandler Carruth	2da477ebfb	[x86] Remove some windows line endings that snuck into the tests here. Folks on Windows, remember to set up your subversion to strip these when submitting... llvm-svn: 225593	2015-01-11 01:36:20 +00:00
Michael Kuperstein	3790301d73	[DAGCombine] Slightly improve lowering of BUILD_VECTOR into a shuffle. This handles the case of a BUILD_VECTOR being constructed out of elements extracted from a vector twice the size of the result vector. Previously this was always scalarized. Now, we try to construct a shuffle node that feeds on extract_subvectors. This fixes PR15872 and provides a partial fix for PR21711.

[DAGCombine] Slightly improve lowering of BUILD_VECTOR into a shuffle.

This handles the case of a BUILD_VECTOR being constructed out of elements extracted from a vector twice the size of the result vector. Previously this was always scalarized. Now, we try to construct a shuffle node that feeds on extract_subvectors.

This fixes PR15872 and provides a partial fix for PR21711.
