Hi,
I am needing a truly exceptions-clean (or exceptions-free) binary due to
some embedding systems platform.
-fno-exceptions is not enough of course.
I am thinking about taking the concept to the backend through multilibs:
add some general -mno-exceptions or alike so there can be a selectable

If the STL is compiled with exceptions support, I can't get rid
off its overhead. It's not just about not using

Did you think of making some extension (using MELT, see

Are there hooks in gcc to deal with negative latencies? In other words,
an architecture that permits an instruction to use a result from an
instruction that will be issued later.
At first glance it seems that it will will break a few things.
1) The definition of dependencies cannot come from th

Do you mean bypasses? If so there is a bypass feature whic

as the stage1 compiler? That would rule out the system compiler
miscompiling stage1.
