[Bug regression/24556] New: gcc can't inline functions using setjmp

[samuel dot thibault at ens-lyon dot org]

Hi,

We have a thread library which can't be optimized as much as before, because
-starting from gcc 3.4- functions calling setjmp can not be inlined. Our
problem is with our switchto function:

void switchto(task_t *cur, task_t *next) {
        if (cur!=next) {
                if (setjmp(cur->buf) == 1)
                        return;
                longjmp(next->buf, 1);
        }
}

We would really prefer _not_ to have to define this as a macro for getting it
correctly inlined in every function that calls it.

Is there a really strong reason for not inlining such function ?

Regards,
Samuel
