Incompatible extension sets FMA4 and FMA3

I have deleted the statement regarding the impossibility of implementing both extensions simultaneously. Either you can or you can't. Near the bottom of the article, it is stated that it "is also possible that future processors will support both forms". I have decided to get on with it by making the change.Swapshop1 (talk) 00:54, 23 April 2011 (UTC)[reply]

Out of date tag

An editor tagged this article with 'out of date' in June 2012, apparently concerned that we do not indicate whether future Intel processors will support the FMA4 instruction. In my opinion we have accurately stated the level of uncertainty about Intel FMA support based on the references currently in the article, so I have removed the tag. Per WP:CRYSTAL it is not up to Wikipedia to predict what Intel will do in the future. It appears that chips supporting the Haswell (microarchitecture) will be the first to support either FMA3 or FMA4. Haswell chips will not be on the market until June 2013. AMD's Piledriver chips are already available and are said to support both FMA3 and FMA4. For example see New “Bulldozer” and “Piledriver” Instructions (PDF), AMD, 2012-10 {{citation}}: Check date values in: |date= (help). EdJohnston (talk) 07:55, 19 March 2013 (UTC)[reply]

AMD Zen and FMA4 support

https://sourceware.org/ml/binutils/2015-03/msg00078.html says: "TBM, FMA4, XOP, LWP: ISAs are not supported." Thus it seems that FMA4 is not supported by AMD Zen. Otherwise an explanation needs to be added. Vincent Lefèvre (talk) 23:02, 21 March 2015 (UTC)[reply]
