IRIX used to use EF_MIPS_* macros and in elf/elf.h there also has comments "The following are unofficial names and should not be used". So we should use EF_MIPS_* to keep same style with the beginning. --- elf/elf.h | 48 +++++++++++++++++++++++++++++++++++++++++++++++- 1 file changed, 47 insertions(+), 1 deletion(-) diff --git a/elf/elf.h b/elf/elf.h index 9c51073f75..43657f6b46 100644 --- a/elf/elf.h +++ b/elf/elf.h @@ -1685,11 +1685,25 @@ typedef struct #define EF_MIPS_PIC 2 /* Contains PIC code. */ #define EF_MIPS_CPIC 4 /* Uses PIC calling sequence. */ #define EF_MIPS_XGOT 8 -#define EF_MIPS_64BIT_WHIRL 16 +#define EF_MIPS_UCODE 16 #define EF_MIPS_ABI2 32 #define EF_MIPS_ABI_ON32 64 +#define EF_MIPS_OPTIONS_FIRST 0x00000080 /* Process the .MIPS.options + section first by ld. */ +#define EF_MIPS_32BITMODE 0x00000100 /* Indicates code compiled for + a 64-bit machine in 32-bit + mode (regs are 32-bits + wide). */ #define EF_MIPS_FP64 512 /* Uses FP64 (12 callee-saved). */ #define EF_MIPS_NAN2008 1024 /* Uses IEEE 754-2008 NaN encoding. */ +#define EF_MIPS_ARCH_ASE 0x0f000000 /* Architectural Extensions + used by this file. */ +#define EF_MIPS_ARCH_ASE_MDMX 0x08000000 /* Use MDMX multimedia + extensions. */ +#define EF_MIPS_ARCH_ASE_M16 0x04000000 /* Use MIPS-16 ISA + extensions. */ +#define EF_MIPS_ARCH_ASE_MICROMIPS 0x02000000 /* Use MICROMIPS ISA + extensions. */ #define EF_MIPS_ARCH 0xf0000000 /* MIPS architecture level. */ /* Legal values for MIPS architecture level. */ @@ -1703,6 +1717,38 @@ typedef struct #define EF_MIPS_ARCH_64 0x60000000 /* MIPS64 code. */ #define EF_MIPS_ARCH_32R2 0x70000000 /* MIPS32r2 code. */ #define EF_MIPS_ARCH_64R2 0x80000000 /* MIPS64r2 code. */ +#define EF_MIPS_ARCH_32R6 0x90000000 /* MIPS32r6 code. */ +#define EF_MIPS_ARCH_64R6 0xa0000000 /* MIPS64r6 code. */ +#define EF_MIPS_ABI 0x0000F000 /* The ABI of the file.
