Simon Pilgrim	bede80a440	[DAGCombiner] SCALAR_TO_VECTOR(EXTRACT_VECTOR_ELT(V,C)) -> VECTOR_SHUFFLE ... This patch attempts to convert a SCALAR_TO_VECTOR using an operand from an EXTRACT_VECTOR_ELT into a VECTOR_SHUFFLE. This prevents many cases of spilling scalar data between the gpr + simd registers. At present the optimization only accepts cases where there is no TRUNC of the scalar type (i.e. all types must match).

David Blaikie	a79ac14fa6	[opaque pointer type] Add textual IR support for explicit type parameter to load instruction ... Essentially the same as the GEP change in r230786. A similar migration script can be used to update test cases, though a few more test case improvements/changes were required this time around: (r229269-r229278) import fileinput import sys import re pat = re.compile(r"((?:=|:|^)\s*load (?:atomic )?(?:volatile )?(.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$)") for line in sys.stdin: sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line)) Reviewers: rafael, dexonsmith, grosser Differential Revision: http://reviews.llvm.org/D7649 llvm-svn: 230794	2015-02-27 21:17:42 +00:00
Chandler Carruth	b264e4a325	[x86] Regenerate a number of FileCheck assertions with my script for ... test cases that will change with the new vector shuffle lowering. This gives us a nice baseline for deltas against. I've checked and removed the cases where there were weird register usage being pinned down, and all of these are extremely pin-pointed tests so fully checking them seems very appropriate. llvm-svn: 218941	2014-10-03 01:06:32 +00:00
Michael Liao	2843625bb5	Fix PR14161 ... - Check index being extracted to be constant 0 before simplfiying. Otherwise, retain the original sequence. llvm-svn: 166504	2012-10-23 21:40:15 +00:00
