--- Comment #3 from TabonyEE at austin dot rr dot com 2007-03-11 18:57 --- By the way, I think emit-rtl.c: change_address_1 could at least use an assert that if the modes are different and the addresses are the same, then mode_dependent_address_p is not true. That is unless

--- Comment #2 from TabonyEE at austin dot rr dot com 2007-03-11 18:28 --- Hhmm. I have made a few other changes and now when I don't define WORD_REGISTER_OPERATIONS, I get correct code. I get an HI load followed by a QI -> SI zero extend, not the preferred POST_MODIFY. I l

--- Comment #1 from TabonyEE at austin dot rr dot com 2007-03-04 02:25 --- For some reason, defining WORD_REGISTER_OPERATIONS prevents Combine from transforming the HI load followed by the AND with 0xFF into a zero-extending QI load. I don't know why this would be. I thin
