OK, yeah, csect is special to XCOFF, so this is not the same concept of sections in ELF. > I haven't verified but it is possible that PGO picks the first pair (zero > value) and have an incorrect counter for `foo`. As I mentioned before, we verified (with `llvm-profdata show --all-functions --counts`) that all the counters are good. > --- > > Does your example imply that the weak symbol `__profc_foo` has 2 definitions > with conflicting values? No, they are identical weak functions. Those offsets are actually from real example using `std::stringbuf`, the foo is actually `_ZNSt3__115basic_stringbufIcNS_11char_traitsIcEENS_9allocatorIcEEEC2Ej`. > Any idea whether the linker bug will be fixed? Unfortunately, I just double confirmed with AIX linker (binder) owner, there is NO plan of lifting the limitation that binder can NOT discard only part of a csect.
