Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org

The generated code for test cases

make a call to the DC mode routine not the expected KC mode routine when
compiled on AIX.
Specifically on gcc119, with GCC mainline revision 262441

The generated code for the other test files fail similarly on AIX.
