Hi All - I wish some insight on the possibility of reallocating a
function stack to a malloced regions in realtime ie I jump out of a
function and the next time I jump in the stack would have moved along
with its data. To me it seems unreliable cause the values in the stack
have no type hence I would not know if the stack value is a data value
or a pointer. If I mistakenly interpret a data value as a pointer I will
update the data value resulting in data corruption. I would really wish
some expert insight in this on this subject.
What you're talking about is something long these lines:
a=malloc(chunk);
memcpy( chunk, SP, size);
SP=chunk;
The only way you "know" what's on your stack is by the variable
declarations you've made in your code. The stack, wherever it is, does
not contain any type info.
