Summary: * Split into two functions, one to test each struct. * R0 and R2 must be defined by an lw with a %got reference to the correct symbol. * Test for $4 (first argument) where appropriate instead of accepting any register. * Test that the two lbu's are correctly combined into $4 Depends on D3844 Reviewers: jkolek, zoran.jovanovic, vmedic Reviewed By: vmedic Differential Revision: http://reviews.llvm.org/D3845 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209424 91177308-0d34-0410-b5e6-96231b3b80d8
