Compilers

Compiler + Options	Notes
gcc 4.1.2 (-Os -freorder-blocks -fno-reorder-functions)	Baseline for testing. Very similar to our reference platform, which uses gcc 4.1.1. Those options above are the default options that we use for compiling. This compiler version apparently does not inline even trivial functions.[1]
