Subject: [RFC PATCH v2 0/2] Segmentation-hardened SafeStack support
Date: Fri, 28 Oct 2016 20:09:19 +0000	[thread overview]
Message-ID: <390CE752059EB848A71F4F676EBAB76D3AC263B8@ORSMSX114.amr.corp.intel.com> (raw)

This series of patches adds support for the separate stack segment feature that I have submitted to LLVM.

I sought to address the feedback from Nagy by defining the "ss" subarch when this feature is enabled.

Michael LeMay (2):
  add support for separate stack segment
  avoid invoking vDSO when separate stack segment is enabled
