Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: X86
Assignee: unassignedb...@nondot.org
Reporter: efrie...@quicinc.com

Testcase:
void ext();

Compile with "clang -O2 -mcmodel=large -fcf-protection". Note the indirect
call to "a", which does not have an endbr.
