This comment here seems imply that `If the function linkage is internal, then the function descriptor symbol can have different linkage as the function symbol.`? And I vaguely recall that why we choose to omit `.lglobl foo{DS}` when foo is internal is because by default, for csect name, it would be `.lglobl` linkage if we don't explicitly set `'.globl` as assembler manual state:

Thanks, You are right. If we can always emit the linkage why not do so? I understand its redundant because the default is correct anyway, but it slightly simplifies the code.
