From 1ac09ef2c611d3113665ec8c74e38b125217edb3 Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Tue, 14 May 2019 14:59:42 +0000 Subject: libgo: reduce overhead for memory/block/mutex profiling Revise the gccgo version of memory/block/mutex profiling to reduce runtime overhead. The main change is to collect raw stack traces while the profile is on line, then post-process the stacks just prior to the point where we are ready to use the final product. Memory profiling (at a very low sampling rate) is enabled by default, and the overhead of the symbolization / DWARF-reading from backtrace_full was slowing things down relative to the main Go runtime.
