You've only "moved" it on nabble.com, that doesn't magically change
history so the email went to the right list and doesn't resend it to
the gcc-help list.

Try using the mailing list, or reposting it to gcc-help.

I really hate this damn machine, I wish that they would sell it.
It never does just what I want, but only what I tell it.

Is possible get label address?

[Borneq]

I send second time this post, because first I send to not this forum, only
move to this.
Is possible in GCC get addres of specified point of code? not function begin
but label, for example:
#include <stdio.h>
#include <stdlib.h>

void* getLabelAddr(void* addr)
{
   return addr;
}
int main()
{
label:
    getLabelAddr(label);
    printf("Hello world!\n");
    return 0;
}

It is error. This is needed for exception handling tests.
