The official answer from IBM XLC is the section is for both .debug_macinfo and .debug_macro For DWARF4 and below, the dwmac section corresponds to .debug_macinfo. For DWARF5 and above, the dwmac section corresponds to .debug_macro. XLC currently does not generate any macro debugging information for DWARF4. - David
