Russ Cox e419535f2a 5g, 6g, 8g: registerize variables again ... My previous CL: changeset: 9645:ce2e5f44b310 user: Russ Cox <rsc@golang.org> date: Tue Sep 06 10:24:21 2011 -0400 summary: gc: unify stack frame layout introduced a bug wherein no variables were being registerized, making Go programs 2-3x slower than they had been before. This CL fixes that bug (along with some others it was hiding) and adds a test that optimization makes at least one test case faster.
