Subject: This is to fix the bug in IntrinsicLowering.cpp,
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=904ebf9bf4e6487892cda2e89b8e6d40803e4733;p=oota-llvm.git

This is to fix the bug in IntrinsicLowering.cpp,
the LowerPartSet(). It didn't handle the situation correctly when
the low, high argument values are in reverse order (low > high)
with 'Val' type i32 (a corner case).
