Created an attachment (id=6942)
 --> (http://llvm.org/bugs/attachment.cgi?id=6942)
test case

With the attached, if I run:

% llc bug.ll -o /dev/null -mcpu=corei7-avx -mattr=+avx

I get the following crash:


Assertion failed: (Result.getValueType() == Op.getValueType() && "Bad
legalization!"), function LegalizeOp, file LegalizeDAG.cpp, line 1705.
