...quickly ran my tests with your changes and a few of them breaks llc while a few other have incorrect assembly. I am attaching the .bc files here. The llc options I use --pre-RA-sched=list-burr and -regalloc=pbqp fun_in_expr3.bc (llc breaks) struct_args_5.bc (incorrect assemly, execution fails) char_char.bc (llc breaks) I haven't really examined what is the reason of failures. Will do so as soon as I get some time off from rest of the stuff. Let me know if you need any specific inputs on pic16 port. - Sanjiv > ------------------------------------------------------------------------ >...

Hello, Attached is a patch which significantly reworks how calls, incoming arguments, and outgoing return values are lowered. It's a major change, affecting all targets, so I'm looking for feedback on the approach. The goal of the patch is to eliminate a bunch of awkward code, eliminate some unnecessary differences between targets, and to facilitate future refactoring and feature work.
