| # The purpose of this test is to make sure that 8 byte instructions do not |
| # cross 64 byte boundaries. If an 8 byte instruction is about to cross such |
| # a boundary then a nop should be added so that the 8 byte instruction starts |
| # 4 bytes later and does not cross the boundary. |
| # This instruction is 8 bytes: paddi 1, 2, 8589934576, 0 |
| # This instruction is 4 bytes: addi 2, 3, 15 |
| # The branches are also 4 bytes each: beq 0, LAB1 (or LAB2) |
