RFC: Strategy for cc0 -> CCmode conversion for the AVR target.

2005-06-04 Thread BjÃrn Haase
Hi, During the last weeks I have experimented a bit with the AVR back-end. IMO there presently are two areas where it is worth to concentrating efforts on: 1.) cc0 -> CCmode transition 2.) splitting of HI- and SI-mode operations so that the RTL finally gets some similarity with the actually exis

Missed optimizations: Constant propagation / algebraic simplification re-run after after reload.?

Hello, when working on the AVR target I stepped over the follwoing issue (IMO not urgent but still bearing quite some potential of improvement): When implementing "lowering" of SImode and HImode expressions to QImode sequences by splitters after reload, quite a number of new optimization oppor

Best thanks for your fast reply! ... did not know that gdb has support for printing RTX. *VERY* useful feature (and much better than temporary including debugging printout commands in the compiler itself :-) ). Yours, Björn
