PandaBoard ES Texas Instruments OMAP4460 ARMv7 dual-core ARM Cortex A9 1.2GHz benchmarking of Ubuntu 12.04 LTS hard-float with Linux 3.2 kernel. This ARMv7 compiler testing of the Precise packages for LLVM Clang 3.0 versus GCC 4.6.3 compilers. Same compiler flags used each time with -O3 CFLAGS/CXXFLAGS. Initial look at LLVM Clang C/C++ compiler performance under dual-core ARMv7 platform dual-core. ARM Linux benchmarking for a future article on Phoronix.com.
