Redirecting to the gcc list for discussion. I'll follow up on that thread directly. r~ -------- Forwarded Message -------- Subject: Re: GCC libatomic questions Date: Wed, 6 Jul 2016 10:27:20 -0700 From: Bin Fan Organization: Oracle Corporation To: Richard Henderson Hello Richard, This is Bin in Sun/Oracle compiler group. Sorry about the long delay for the libatomic ABI specification I mentioned a long long time ago. I was assigned to some other tasks. Please find a draft of the libatomic ABI specification attached. The text is also pasted at the end of the email. The goal of the ABI specification is twofold. First is to check with the GCC community that the ABI matches the latest GCC libatomic implementation. This would make sure that GCC and Oracle Developer Studio C/C++ compiler can work well together w/o any compatibility issues on Solaris/Linux + SPARC/x86. Second and a longer term goal is to integrate the libatomic ABI into the current SPARC/x86 ABI specifications. Could you please review the draft and/or forward it to the community for review? Thanks, - Bin
