yay for steamroller approach without actually addressing any of my
valid concerns. I'd expect nothing less from you Chandler, nice job..
It's not like they will be contributing code to this area and or have
contributed much to the areas of offloading. (Sorry Hal, but I may be
mistaken in your case.. I'd need to check commit logs)
The reasons Hal and others "support" your proposal is based on
"interest" or speculation at best. They haven't committed to
contribute code and their expertise in the areas of offloading is
probably narrow band. (Again sorry Hal, I know you work inside the OMP
I expect if we had to take a vote it would be myself (who has
contributed to OMP btw, most of the ARM port, cmake stuff and lots of
code reviews) and Intel - (who has significantly contributed to OMP).
Just because I don't submit patches to the pass manager doesn't mean I
have zero contribution. I'm annoyed you don't even have your facts
My vote isn't -1, but it is lets revisit this when the project is more
mature. Are you totally blind to the fact that we DO NOT NEED ANOTHER
PROGRAMMING MODEL. There should be super strong and compelling reasons
to do that, which you have not demonstrated.
New programming model == super big hammer. It's like saying everything
else is so broken beyond repair we need to invent something wholly
Intel can you please weigh in
