Hi, in mmu less system, stack overflow is extremely danger for userland application, so i just try to take advantage from using GCC stack check options, BTW: our system is running on a ARM7TDMI, mmuless platform, and we use GCC 4.3.3, also build userland to use ARM EABI,
Here are my questions: 1. 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. 2. tried explicit compile application with -fstack-limit-register=R10, but seems no binary change with or without this option. 3. anybody tried -fstack-check option on ARM or other mmuless system? will this option help in runtime stack check? Thanks, Haitao _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
