--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
I frequently use raise(SIGSTOP) ... (or x86 specific you can do asm ("int 3");
or whatever that break thing was...

Note I think that a compiler-only-side implementation might not be possible
on all targets given it might be dependent on OS and debugger preferences
as well?
