# The effect of the .stack definition is like setting STACK_ADDR to 0x80000,
# except that the setting can be overridden, e.g. --defsym _stack=0xff000,

# N.B. We can't use PROVIDE to set the default value in a symbol because
# the address is needed to place the .stack section, which in turn is needed
# to hold the sentinel value(s).
