From 1c1df0198b30e180bd63891727fa1c3e0c96eb8e Mon Sep 17 00:00:00 2001 From: Pranith Kumar Date: Sun, 26 Feb 2017 11:53:44 -0500 Subject: linux-user: Add signal handling support for x86_64 Note that x86_64 has only _rt signal handlers. This implementation attempts to share code with the x86_32 implementation.
