Phoronix: LLVM 3.6 & Clang 3.6 Deliver More Features, Complete C++14 Support

LLVM 3.6 and Clang 3.6 are due to be released any day now and with this new version of the increasingly-used BSD-licensed compiler infrastructure stack are many improvements and new features to benefit the vast majority of users...

Nice to see that OpenMP support is finally getting in. I'm going to be very interested to see benchmarks when 3.7 comes out with full support as that's been the last stronghold of GCC.

as that's been the last stronghold of GCC.

Haha, right after LLVM will be able to generate code for MSP430 or Atmel AVR. You see, whole Arduino stuff is actually just some avr gcc, soome libs and limited subset of C++. So mumbluing about "last' stronghold is a misnomer .

Good to hear OMP is probably in 3.7. We'll finally get some apples to apples testing. I fully expect GCC to surrender the performance crown by 4.0.

There's really no reason to go with an Arduino over a Beaglebone Black or similar modern ARM-based hobbyist microcontrollers.

Regardless though I was talking about the performance arena. As it stands the primary reason to use GCC for production applications is OpenMP otherwise GCC and LLVM have been in a situation where they were trading blows with each other on binary performance, with LLVM winning out on compilation speed.

There is also runtime performance to consider. GCC has continues to improve as well. Competition in this space has been pretty good for both projects and I expect that to continue

Yes... That's what I was talking about, and then added that LLVM wins out in the end because it has a faster compilation speed, with comparable performance. I agree though, competition in this space has been a good thing particularly as it's forced things towards operating in a more standard compliant as opposed to GNU-reliant manner.

Wohoo! Finally nested namespace declaration! Why took it two decades?
Let's party!!

(Yes i am aware not being a productive part of the gcc vs clang discussion. For my current project I switched to clang a week ago. Much nicer errors, significant compile time speedup )

Isn't their power use in completely different spheres? One you can run off a small battery for weeks, the other would exhaust a big cellphone battery in a day?

(disclaimer: Have never used arduino, only msp430)

Have been using both gcc and clang for my projects for well over two years now, find compiler fanboyism rather hilarious.
