Bug ID: 81645
Summary: Learn UBSAN to support -fsanitize=builtin
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org

Target Milestone: ---
I've just read LLVM weekly:
* The Undefined Behavior Sanitizer (UBSan) learned to detect undefined
behaviour in calls to builtins. [r309459](http://reviews.llvm.org/rL309459).
And we can also support that. Currently they instrument CLZ and CZT builtins
family. But maybe there are also others that worth adding?
