APAR status
Closed as program error.
Error description
When using the -qnospeculateabsolutes option with a -bImport symbol file and an IPA link step, struct member accesses are not correctly treated as speculative-load unsafe.
Local fix
Problem summary
Members of struct data structures are not being marked as do-not-speculate when -qnospeculateabsolutes is used.
Problem conclusion
The compiler was modified to ensure that all struct members are marked as do-no-speculate when the struct variable name is listed in the -bImport file.
Temporary fix
