Is Assembly Still Relevant To Most Linux Software?

Steve McIntyre and the Linaro Enterprise Group recently analyzed Ubuntu and Fedora software packages to see what software was still relying upon hand-written Assembly code. This was done to see how much real Assembly is being used, to see what the code was used for, and whether it was worth porting to 64-bit ARM / AArch64 / ARMv8.

C Language Modules For LLVM Still Being Tackled

Last year at the LLVM developers' meeting it was proposed by an Apple engineer the concept of "modules" for C code in LLVM/Clang to replace the common development approach for C/C++ languages of including header files and passing the library to the linker. LLVM modules seek to take a different approach.

Compilation Times, Binary Sizes For GCC 4.2 To GCC 4.8

Compiler benchmarks at Phoronix commonly look at the performance of resulting binaries while less of a focus is the compilation time and binary sizes. However, a developer has carried out GCC benchmarks of the compilation times and binary sizes in different scenarios for GCC releases going from GCC 4.2 to the upcoming GCC 4.8.
