llvm dev - Oct 2011 - [LLVMdev] release notes: please mention Intrinsic::memory_barrier removal in 3.0

Hi,

Looks like the memory_barrier intrinsic got removed in 3.0 and replaced with
fence intrinsics.
Could someone who understands this change better than me please update the 3.0
release notes?
Also the LangRef still mentions llvm.memory.barrier but this is gone from 3.0.

Best regards,
--Edwin

Any comments on your transition would be appreciated.

Thanks.
My code compiles now, but I haven't actually had time to test it on a
non-x86 architecture
(on an x86 architecture the fence I was using was a nop).
I'll probably do some tests in the weekend and let you know how the
conversion went.

Do these need to go into the 3.0 branch?
