From be12681896fab9455eb65ea124df423b462e0072 Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Tue, 18 Oct 2011 00:21:21 -0500 Subject: [PATCH] pack-objects: mark add_to_write_order() as inline This function is a whole 26 bytes when compiled on x86_64, but is currently invoked over 1.037 billion times when running pack-objects on the Linux kernel git repository. This is hitting the point where micro-optimizations do make a difference, and inlining it only increases the object file size by 38 bytes. As reported by perf, this dropped task-clock from 84183 to 83373 ms, and total cycles from 223.5 billion to 221.6 billion. Not astronomical, but worth getting for adding one word.
