B.2.11 #pragma must_have_frame
#pragma must_have_frame(funcname [,funcname])
|
This pragma requests that the specified list of functions always
be compiled to have a complete stack frame (as defined in the System V ABI).
You must declare the prototype for a function before listing that function
with this pragma.
extern void foo(int);
extern void bar(int);
#pragma must_have_frame(foo, bar)
|
This pragma is permitted only after the prototype for the specified
functions is declared. The pragma must precede the end of the function.
void foo(int) {
.
#pragma must_have_frame(foo)
.
return;
}
