Hi, I am working on SDCC for quite some time
now. I have noticed that many a times iCode generation phase Produces incorrect iCode but in the CSE
pass (for eg. In algebraicOpts()) Sandeep Dutta have put some kludgy
fixes which convert that Incorrect iCode to correct one. I wanted to know was there any specific
reason for this behavior. Why don’t we generate the correct iCode in the
ast2iCode pass itself. I am asking this because there is a
SERIOUS DRAWBACK of this approach that one cannot disable the optimization pass
(CSE) as In such case incorrect assembly will be
produced. If I use –nogcse option then compiler will generate incorrect
code. Please let me know the reason for it as I want
to disable the optimization passes. Regards, Jatin Bhateja
