Subject: RE: [PATCH] [ARC] Add support for atomic memory built-in.
Date: Wed, 09 Dec 2015 14:31:00 -0000 [thread overview]
Message-ID: <098ECE41A0A6114BB2A07F1EC238DE896616B33C@de02wembxa.internal.synopsys.com> (raw)
In-Reply-To: <5667B7FA.5070801@amylaar.uk>
I will add this text before "*memory_barrier" pattern:
;; For ARCHS, we use a hardware data memory barrier that waits for
;; completion of current data memory operations before initiating
;; similar data memory operations.
Once done, I will commit it.
Thanks,
Claudiu

The comment before "*memory_barrier" could use some elaboration on what it does for TARGET_HS.
Otherwise, this is OK.
