C++ Doesn't Change The Speed Of GCC

With GCC 4.8 using C++ as its implementation language of the compiler, some have questioned whether the compiler is as fast as when written in C. Here's some benchmarks showing C vs. C++ performance with GCC.

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.

GCC 4.8 Has Support For AMD Steamroller, Jaguar

Aside from improvements to Link-Time Optimizations, run-time library improvements, and a new optimization level, the coming release of GCC 4.8 also features support for yet-to-be-out AMD hardware. AMD's Steamroller "Bulldozer 3" processor is already supported with compiler optimizations and so is AMD Jaguar, their new low-power APU that's rumoured to be in the next-generation consoles.
