This reverts commit e3d522dd6b52025191bacfab241f130e9870941f. Reason for revert: Disabling test failing in downstream projects. Original change's description: > Revert "Floating-point exception observer for unit tests" > > This reverts commit 3fb3939896f6270d48aff34eee2946bd7661bd63. > > Reason for revert: Downstream projects failures. > > Original change's description: > > Floating-point exception observer for unit tests > > > > This CL adds a simple tool that let a unit test fail if a floating > > point exception occurs. It is possible to focus on specific exceptions. > > Note that FloatingPointExceptionObserver is only effective in debug > > mode. For this reason, the related unit tests only run in debug mode. > > Plus, due to some platform-specific limitations, not all the floating > > point exceptions are available on Android. > > > > Bug: webrtc:8948 > > Change-Id: I0956e27f2f3aa68771dd647169fba7968ccbd771 > > Reviewed-on: https://webrtc-review.googlesource.com/58097 > > Commit-Queue: Alessio Bazzica <alessiob@webrtc.org> > > Reviewed-by: Patrik Höglund <phoglund@webrtc.org> > > Cr-Commit-Position: refs/heads/master@{#22768} > > TBR=phoglund@webrtc.org,alessiob@webrtc.org,kwiberg@webrtc.org > > Change-Id: I0fd3d114ab4a348fd46339e98273e19c1ac1c6dc > No-Presubmit: true > No-Tree-Checks: true > No-Try: true > Bug: webrtc:8948 > Reviewed-on: https://webrtc-review.googlesource.com/67380 > Reviewed-by: Alessio Bazzica <alessiob@webrtc.org> > Commit-Queue: Alessio Bazzica <alessiob@webrtc.org> > Cr-Commit-Position: refs/heads/master@{#22769} TBR=phoglund@webrtc.org,alessiob@webrtc.org,kwiberg@webrtc.org # Not skipping CQ checks because original CL landed > 1 day ago.
