#
# In contrast, the split layout has both a src and asm window, plus
# the same status and cmd windows.
#
# Of particular interest here is the first test, where we maximise the
# cmd window before switching to split. This requires gdb to realise
# that it has to shrink the cmd window, even though this is something
# gdb usually avoids doing.

# The test then switches to the 'split' layout, and calculates the
