[llvm-commits] [ARM] Scheduler FixedFrame object vs byval formal parameters

[Stepan Dyatkovskiy]

Hi all!

Small but very important issue is, that 
SchedulerDAGInstrs::buildSchedGraph ignores dependencies between 
FixedStack objects and byval parameters. So loading byval parameters 
from stack may be inserted *before* it will stored, since these 
operations are treated as independent.

Frankly right now, I couldn't found better solution than make byval 
arguments dependent from all fixed-frame objects. Perhaps guys, you have 
any ideas?

Please find patch in attachment.
