If foo is instantiated elsewhere then
this check could still be useful.
My opinion is that since it may be instantiated as an signed type,
then warning is pointless there.

Yes. But only very very late in the compilation, once all normal
re-ordering and optimization has been completed. I think it's probably
final that folds out
Hi! I'm new of Linux and I'm not good.
How can I install Gcc if I don't have any C compiler?

install rpm package for your distribution, or download gcc in binary form.

SECONDARY_RELOAD_CLASS has the option of limiting the reload class.
The mn10300 has a generic SImode reload_in that allows GENERAL_REGS,
but SECONDARY_RELOAD_CLASS specifies a smaller class based on the
registers that need reloading.

I think that's valid gnu99.
Speaking of typeof, should typeof (vla) follow the same rules as for
sizeof (vla)? vla, evaluate, otherwise, no eval.

How would typeof be able to eval anything?

I'd hesitate to apply patches to default_secondary_reload. If your port

as it provides a much better interface.

It's not yet supported. Remember, bl has a long range but clobbers lr, and
there's no long branch instruction, so you h

Thumb only has very limited (256 byte) direct branch offsets, so tail calls
aren't possible/useful.
