Hello AMD
I have replaced all a*b+c integer calculations with mad24 in my code (and I have quite a few of those!). Unfortunately I see no runtime difference at all.
Questions:
1) Does your OpenCL compiler automatically replace all a*b+c with mad24 ?
2) Does your OpenCL implementation support mad24 - or does the compiled code silently replace all mad24 with a*b+c ?
Thanks for your reply Micah.
The code runs on a HD6970. Yes, it is memory bound - but since I have lots of those a*b+c I thought I might see at least *some* difference. No?
