LLVM/Clang vs. GCC On The ARM Cortex-A15 Preview

The latest ARM Cortex-A15 benchmarks on Phoronix is an extension of the earlier compiler testing from this modern ARM CPU found on the Samsung Exynos 5 Dual within the Samsung Chromebook. In this round of performance testing, the LLVM/Clang compiler performance is compared to recent releases of the GNU Compiler Collection on this latest-generation ARM hardware.

Benchmarking LLVM/Clang 3.2, GCC 4.8, DragonEgg Compilers

Earlier this week I shared some updated benchmarks of the latest development code for LLVM/Clang 3.2 on an Intel Core i7 processor. Now from this same setup to complement the LLVM 3.1/3.2 benchmarks are results of the GCC 4.7.2 compiler, the latest GCC 4.8 development snapshot, and benchmarks of GCC when using LLVM's DragonEgg 3.1/3.2-SVN optimizer plug-in.

GCC 4.8 Compiler On AMD's Eight-Core Piledriver

This month from CPUs based upon AMD's new Piledriver micro-architecture I have delivered results of compiler tuning on AMD's Open64 compiler as well as GCC bdver2 tuning. That initial testing from an AMD FX-8350 Eight-Core processor didn't show any big boost out of the "bdver2" target with the new BMI/TBM/F16C/FMA3 instruction set extensions. Testing in this article from the AMD FX-8350 are GCC compiler benchmarks of the 4.6.3, 4.7.2, and 4.8.0 development snapshots to look for performance improvements on this new high-end AMD processor when using the very latest GCC compiler code.
