Re: [avr-chat] The silent death of -mint8

[Weddington, Eric]

Hi Ruud,

This is nothing new. The developers are aware of this, and we've been talking 
about it recently.

-mint8 was already a hack, it never worked with avr-libc, and if you ever ran 
into a bug with it, you've always been on your own.

Yes, we all know that the point is to improve the optimization such that -mint8 
would never be necessary. I know that Georg-Johann Lay has been working on that 
recently in trunk.

And it's wrong of you to think that we "forget" our developers, or that we have 
no interest in improving the situation.

Why not try your hand at helping to fix the avr backend of gcc?
