From db72219339ae0366e28cd53e20e8afafa1422e6c Mon Sep 17 00:00:00 2001 From: ian Date: Fri, 17 Apr 2015 21:29:20 +0000 Subject: [PATCH] PR go/64683 runtime/pprof: Assume function with no name is in runtime. GCC PR 65797 causes some of the runtime functions to be compiled with no name in the debug info. This in turn causes the runtime/pprof test to fail as reported in GCC PR 64683. There are no good choices when a function has no name in the debug info, but here we assume that if we see such a function while reading the runtime functions, we assume that it is also a runtime function. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@222200 138bc75d-0d04-0410-961f-82ee72b054a4 --- libgo/go/runtime/pprof/pprof.go | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/libgo/go/runtime/pprof/pprof.go b/libgo/go/runtime/pprof/pprof.go index 9c63ccd90b5..38593afb6f2 100644 --- a/libgo/go/runtime/pprof/pprof.go +++ b/libgo/go/runtime/pprof/pprof.go @@ -351,6 +351,10 @@ func printStackRecord(w io.Writer, stk []uintptr, allFrames bool) { if !show && !strings.Contains(name, ".") && strings.HasPrefix(name, "__go_") { continue } + if !show && name == "" { + // This can happen due to http://gcc.gnu.org/PR65797. + continue + } show = true fmt.Fprintf(w, "#\t%#x\t%s+%#x\t%s:%d\n", pc, name, pc-f.Entry(), file, line) } -- 2.11.4.GIT
