# This test aims to trigger live-range splitting at a place where %0 subranges
|
|
# are all dead, but the main live-range of %0 is still alive. %0 main range is
|
|
# kept alive simply by not using undef. Then, the splitting is triggered by
|
|
# creating two points of high register pressure:
|
|
# - One where %0 main range is the only live live-range: this will force the
|
|
# insertion of a split for %0 main range.
|
|
# - One where %0.subrange is live, so that the interference check in regalloc
|
|
# triggers the splitting heuristic.
