Re: [avr-llvm-devel] Current Status?

[Borja F. <bor...@gm...>]

Ahh ok, I will take a look then.

Update: I've already implemented conditional branches for if() conditions
(BR_CC node). I still need to work on overriding some virtual functions in
some interfaces to improve the generated code. Then I will move to SETCC
and SELECT nodes which are used in things like: a = (b > c) and a = (b > c)
? 1 : 2 respectively.
I'm happy because we can now compile loops :)
