ACE claims better result than LLVM for ARM 9 ?

Weird that they don't give any number and use ARM 9, do they mean cortex-a9 ?

Why don't ask them? ARM9 is either ARMv4 (ARM9) or ARMv5 (ARM9E), so,
not even close to ARMv7 :slight_smile:
Also ask them about time machine they used - "latest LLVM" at 12 July
wasn't 3.0, really.

They’re also using 3.0, which is the release from December 2011.

It's impossible to say. This sort of marketing statement is impossible to refute, because there are no details. Who knows whether they compared against LLVM fairly with it tuning for the right architecture, had frame pointers set the same way, etc...

ps, it's hard to take them seriously when they make factually incorrect statements like LLVM 3.0 being the latest, and give no way to validate their claims.

I guess we should be flattered that companies are using LLVM as the baseline for their bogus assertions.
