2021-08-09runtime/cgo: when using msan explicitly unpoison cgoCallersIan Lance Taylor
This avoids an incorrect msan uninitialized memory report when using runtime.SetCgoTraceback when a signal occurs while the fifth argument register is undefined. See the issue for more details.

2018-07-04runtime: support capturing C backtrace from signal handler on darwin/amd64Nikhil Benesch
The implementation is mostly copied from the commit that added linux/amd64 support for this feature (https://golang.org/cl/17761).

2016-05-31runtime: pass signal context to cgo traceback functionIan Lance Taylor
When doing a backtrace from a signal that occurs in C code compiled without using -fasynchronous-unwind-tables, we have to rely on frame pointers. In order to do that, the traceback function needs the signal context to reliably pick up the frame pointer.

2016-04-01runtime: support symbolic backtrace of C code in a cgo crashIan Lance Taylor
The new function runtime.SetCgoTraceback may be used to register stack traceback and symbolizer functions, written in C, to do a stack traceback from cgo code. There is a sample implementation of runtime.SetCgoSymbolizer at github.com/ianlancetaylor/cgosymbolizer. Just importing that package is sufficient to get symbolic C backtraces. Currently only supported on linux/amd64. Change-Id: If96ee2eb41c6c7379d407b9561b87557bfe47341 Reviewed-on: https://go-review.googlesource.com/17761 Reviewed-by: Austin Clements <austin@google.com>
