The relocs are always passed as Rela structures; if the section

LOCAL_SECTIONS is an array giving the section in the input file

The global hash table entry for the global symbols can be found

When generating relocateable output, this function must handle

STB_LOCAL/STT_SECTION symbols specially. The output symbol is
