Just a random idea to even more improve simulation speed in GHDL: Using Link Time Optimisation to inline parts of the GRT library. -GCC version >4.5 support Link Time Optimisation (LTO) -Alternatively LLVM code can be generated from a GCC frontend using the DragonEgg project (http://dragonegg.llvm.org/), LLVM is also a compiler middle-end/backend that support LTO. SVN r116 and r118 are commits about LLVM, but I don't know if it still works on recent versions of GCC/DragonEgg.
