3 ; July 6, 2002 -- LLC Regression test
4 ; This test case checks if the integer CC register %xcc (or %ccr)
5 ; is correctly spilled. The code fragment came from function
6 ; MakeGraph in Olden-mst.
7 ; The original code made all comparisons with 0, so that the %xcc
8 ; register is not needed for the branch in the first basic block.
9 ; Replace 0 with 1 in the first comparson so that the
10 ; branch-on-register instruction cannot be used directly, i.e.,
11 ; the %xcc register is needed for the first branch.
