about

nx_gcc_race.nx -- the team's OWN capability to race a production compiler. Until now I measured gcc by hand in a shell; that is not the team racing. This lets the TEAM do it: it forks gcc -O2 to compile a C source, forks objdump to disassemble, and PARSES the instruction count of the function body itself. With this, the team can race gcc on any kernel, autonomously, and judge its own standing (win / tie / loss) -- the prerequisite for hunting an EXCEED instead of me hand-picking targets. license_tier: ORIGINAL
