APAR status
Closed as program error.
Error description
Wrong program output if routine is inlined in source compiled using Altivec and IPA.
Local fix
If possible avoid explicit cast of vector types to other vector types. Or lower optimization level to avoid using IPA.
Problem summary
USERS AFFECTED: Users using altivec in their source and invoking IPA may be affected by this issue. PROBLEM DESCRIPTION: IPA is changing the type of a symbol to avoid a conversion, but this is causing incorrect behavior when the temporary is being used else where.
Problem conclusion
IPA has been changed so that it will not change the type of the symbol, but leave the conversion in the code.
Temporary fix
