Closed as program error.
XLC compiler does not detect __rotatel4 pattern. Other compilers detect rotate code automatically.
USERS AFFECTED: Users that compile with -q64 and optimization and have a specific shift pattern that could be a rotate may be affected by this issue. PROBLEM DESCRIPTION: The optimizer failed to detect opportunity to use a rotate instruction in 64-bit mode.
The issue has been fixed.
