Looking at following codes in glibc source
(sysdeps/mips/elf/ldsodefs.h), I thought r_info on 64bit mips needs
special handling. Is not this structure used for 64bit kernel
modules?
typedef struct
{
Elf32_Word r_sym; /* Symbol index */
unsigned char r_ssym; /* Special symbol for 2nd relocation */
unsigned char r_type3; /* 3rd relocation type */
unsigned char r_type2; /* 2nd relocation type */
unsigned char r_type1; /* 1st relocation type */
} _Elf64_Mips_R_Info;
typedef union
{
Elf64_Xword r_info_number;
_Elf64_Mips_R_Info r_info_fields;
} _Elf64_Mips_R_Info_union;
...
typedef struct
{
Elf64_Addr r_offset; /* Address */
_Elf64_Mips_R_Info_union r_info; /* Relocation type and symbol index */
Elf64_Sxword r_addend; /* Addend */
} Elf64_Mips_Rela;
#define ELF64_MIPS_R_SYM(i) \
((__extension__ (_Elf64_Mips_R_Info_union)(i)).r_info_fields.r_sym)
...
#undef ELF64_R_SYM
#define ELF64_R_SYM(i) ELF64_MIPS_R_SYM (i)
