AMD Releases Optimizing C/C++ Compiler For Ryzen

[andrei_me]

What part of "we have been pushing changes upstream for a quite a while" was not clear ?

Should we expect no differences in performance of the generated binaries then?

Why would marketing claim it is an "AMD compiler" if it's just upstream llvm instead of advertising that the company is contributing to free software?

1. We're talking about marketing teams
2. We're talking about AMD's marketing team

Why would we try to push a binary upstream ?

I won't use any vendor compiler!

Because it sure looks like you took clang, made some Ryzen optimizations, and are now trying to make your own icc/icl.

While technically legal, it's a shitty thing to do. It seems like a very backwards step given all of your recent open-source work.

[bridgman]

yeahhh I don't think this is gonna be upstreamed

That one is pretty interesting, fuck you AMD

Huh ? The compiler teams have been submitting Ryzen support upstream into LLVM for quite a while now.

This is just a binary release with the standard binary EULA as far as I know.

Why would we try to push a binary upstream ?

But the application has to be compiled with a specialized architecture flag? Thus, no one will benefit from it?

Erh ... surely people who turn on the relevant architecture flag will benefit?

Or are you assuming that the people who want the extra performance won't recompile from source for some unspecified reason?

[ossuser]

Seeing AMD going opensource big time, I don't understand this.

Does this also mean that gcc /clang didn't get the full set of Ryzen optimizations yet ?

Might this be a 'temporary' compiler for demonstrating the power of Ryzen 7/Whitehaven/Naples etc ?

@bridgman: any idea ?

Judging only by the description given in the article does it sound very much like they couldn't have cared less if they've tried and that this was the last compiler ever to have come from AMD.

I'm curious if the benchmark will reflect this or if it turns out to be some wonder-magic compiler against all expectations.
