Re: [patch] Fix behavior of TER on unrolled loops



Seems to me that for a lot of things, e.g. loop optimizations, you really need to know target details such as addressing modes,

What? You must be thinking of different types of loop opts than i am. What high level loop optimization do you think requires knowledge of addressing modes?


strength reduction needs to know about addressing modes, but that's
about it.  No other loop optimization should need to care about them.
And I would not consider SR a "high level loop optimization".

We went through all this on IRC... no it's not a high level loop optimization, but it's part of the middle end, and Dan claimed that that should be completely target independent, which I thought was a silly notion.
