Hello, Is there a way to disable this for a specific function? Something like __attribute__((unprotected)) maybe? I have a function that appends two string literals* (of known size to the compiler) into a char array that is 43 bytes larger than the two literals, but gcc is still emitting the stack guard instructions. Since I know the stack cannot be smashed (and gcc is apparently unable to determine that for itself), I'd like to turn it off for that function. It's a a heavily used function that is inlined, so it's causing increased code size and slower performance for no reason. Thanks, --Mike *It actually does more, but eliminating all but these two memcpy()s still produces the stack guard; if reduced to a single memcpy(), gcc does detect it cannot smash the stack and doesn't emit the stack guard.
