-fstack-limit-register not work for ARM?

Hi,

we recently use GCC 4.3.3 to build userland application use ARM EABI,
for running on a ARM7TDMI, mmuless platform.

after explicit compile application with -fstack-limit-register=R10,
there is no binary change with or without this option. Does this option work?

another thing, in old GCC 3.x series, there is a -mapcs-stack-check,
but once GCC and ARM ABI upgraded to use AAPCS,
seems there is no such option like -maapcs-stack-check.


Thanks,

Haitao
