Summary: GCC testcases that clang fails to devirtualize
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
The attached testcases were recently posted to the gcc mailing list. GCC from
top-of-tree apparently manages to completely devirtualize the code in "main"
for
each of them, but clang does not at -O4.
