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