This is a reland of dc32cc00e80972223767be339f9318b803f4a2ae Relanding because this CL was not the culprit for the Chrome bot. (This code shouldn't even be executed in Chrome). Original change's description: > Android: Add helper methods for printing native stack traces > > This CL adds utility functions to unwind the stack for a given thread on > Android ARM devices. This works on top of unwind.h and unwinds native > (C++) stack traces only. Unwinding a thread from another thread is done > by overriding the signal handler with a custom function and then > interrupting the specific thread. > > Bug: webrtc:10168 > Change-Id: If5adffd3a6bb57bf502168743e09a7eefc292bf3 > Reviewed-on: https://webrtc-review.googlesource.com/c/118141 > Commit-Queue: Magnus Jedvert <magjed@webrtc.org> > Reviewed-by: Tommi <tommi@webrtc.org> > Cr-Commit-Position: refs/heads/master@{#26328} TBR=tommi Bug: webrtc:10168 Change-Id: I4c33c2c147cf10c0172c98a55d32dd35a08517c8 Reviewed-on: https://webrtc-review.googlesource.com/c/118704 Reviewed-by: Magnus Jedvert <magjed@webrtc.org> Commit-Queue: Magnus Jedvert <magjed@webrtc.org> Cr-Commit-Position: refs/heads/master@{#26341}
