Bug ID: 86414
Summary: AIX generates wrong
Product: gcc

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

Target Milestone: ---
The generated code for test cases

gcc/testsuite/gcc.target/powerpc/mulkc3-3.c
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.
