Subject: [RFC PATCH v2 0/2] Segmentation-hardened SafeStack support
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
