The later. From <elf.h>:
/* Legal values for st_other field of Elf64_Sym. */
#define STO_ALPHA_NOPV 0x80 /* No PV required. */
#define STO_ALPHA_STD_GPLOAD 0x88 /* PV only used for initial ldgp. */
If you are using these, should ELF64_ST_VISIBILITY be extended?
Also from <elf.h>:
/* How to extract and insert information held in the st_other field. */
#define ELF32_ST_VISIBILITY(o) ((o) & 0x03)
/* For ELF64 the definitions are the same. */
#define ELF64_ST_VISIBILITY(o) ELF32_ST_VISIBILITY (o)
That is what elflint checks here.
