From 66286a53d5f325b1b396d0d590dfa1c6aa51cbca Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Thu, 30 Apr 2015 17:21:29 +0000 Subject: [PATCH] compiler: Mark non-escaping variables that aren't addressed. When optimizing allocations, only variables that had their address taken somewhere in the program were marked as non-escaping. There are several cases where non-addressed variables might cause extra allocations.
