Hi,
The jmp_buf defined in setjmp.h needs a large buffer, typedef __int64 jmp_buf[48]; //384 bytes
As we checked in function setjmp/longjmp used by Cortex M0/M3, it is used to save only few run-time data such as R0, R1, ...
On some platform which has very limited memory resource, the 384 bytes seems too expensive. What's the minimal size of jmp_buf?
Thanks!
I have to agree with you! Haha ...
