From 2541cc81978dc5e41e2e2db6345d8ca7a365ca8c Mon Sep 17 00:00:00 2001 From: Russ Cox Date: Wed, 19 Feb 2014 10:00:44 -0500 Subject: [PATCH] cmd/ld: drop gcargs, gclocals symbols from symbol table Update #6853 Every function now has a gcargs and gclocals symbol holding associated garbage collection information. Put them all in the same meta-symbol as the go.func data and then drop individual entries from symbol table. Removing gcargs and gclocals reduces the size of a typical binary by 10%.
