The static PIE patch was updated by Juro Bystricky <juro.bystricky@intel.com> to work with gcc 7.3. This update from the stable gcc 7 branch includes the retpoline functionality which is useful to assist with recent security issues. Two backported patches were dropped as they're included in 7.3.

Prevent a segmentation fault which occurs when using incorrect
|
|
structure trying to access name of some named operators, such as
|
|
CPP_NOT, CPP_AND etc. "token->val.node.spelling" cannot be used in
|
|
those cases, as is may not be initialized at all.
