machines. See `function.c' for details.
The MIPS 3.0 linker does not like functions that dynamically
allocate the stack and have 0 for STACK_DYNAMIC_OFFSET, since it
looks like we are trying to create a second frame pointer to the
function, so allocate some stack space to make it happy. */
The MIPS ABI states that functions which dynamically allocate the
stack must not have 0 for STACK_DYNAMIC_OFFSET, since it looks like
we are trying to create a second frame pointer to the function, so
allocate some stack space to make it happy.
However, the linker currently complains about linking any code that
dynamically allocates stack space, and there seems to be a bug in
STACK_DYNAMIC_OFFSET, so don't define this right now. */
