36 | # The effect of the .stack definition is like setting STACK_ADDR to 0x80000, |
37 | # except that the setting can be overridden, e.g. --defsym _stack=0xff000, | |
38 | # and that we put an extra sentinal value at the bottom. | |
39 | # N.B. We can't use PROVIDE to set the default value in a symbol because | |
40 | # the address is needed to place the .stack section, which in turn is needed | |
41 | # to hold the sentinel value(s). | |
