4 ; Test that the SIMD game of life example from the NaCl SDK has an inner loop
5 ; that contains the expected shufflevector instructions. First run the ABI
6 ; simplifications on the code, then run the translator's peepholes.
7 ;
8 ; The stable PNaCl bitcode ABI doesn't have shufflevector nor constant vectors,
9 ; it instead has insertelement, extractelement and load from globals. Note that
10 ; `undef` becomes `0` in the constants.
11
12 ; The datalayout is needed to determine the alignment of the globals.
