The symbol flags field is reserved for future use. */ 1063 unsigned long ms_info; 1064 } Elf32_Internal_Msym; 1065 1066 #define ELF32_MS_REL_INDEX(i) ((i) >> 8) 1067 #define ELF32_MS_FLAGS(i) (i) & 0xff) 1068 #define ELF32_MS_INFO(r, f) (((r) << 8) + ((f) & 0xff)) 1069 1070 /* MIPS ELF reginfo swapping routines. */ 1071 extern void bfd_mips_elf64_swap_reginfo_in 1072 (bfd *, const Elf64_External_RegInfo *, Elf64_Internal_RegInfo *); 1073 extern void bfd_mips_elf64_swap_reginfo_out 1074 (bfd *, const Elf64_Internal_RegInfo *, Elf64_External_RegInfo *); 1075 1076 /* Masks for the info work of an ODK_EXCEPTIONS descriptor. */ 1077 #define OEX_FPU_MIN 0x1f /* FPEs which must be enabled. */ 1078 #define OEX_FPU_MAX 0x1f00 /* FPEs which may be enabled. */ 1079 #define OEX_PAGE0 0x10000 /* Page zero must be mapped. */ 1080 #define OEX_SMM 0x20000 /* Force sequential memory mode. */ 1081 #define OEX_FPDBUG 0x40000 /* Force precise floating-point 1082 exceptions (debug mode). */ 1083 #define OEX_DISMISS 0x80000 /* Dismiss invalid address faults. */ 1084 1085 /* Masks of the FP exceptions for OEX_FPU_MIN and OEX_FPU_MAX. */ 1086 #define OEX_FPU_INVAL 0x10 /* Invalid operation exception. */ 1087 #define OEX_FPU_DIV0 0x08 /* Division by zero exception. */ 1088 #define OEX_FPU_OFLO 0x04 /* Overflow exception. */ 1089 #define OEX_FPU_UFLO 0x02 /* Underflow exception. */ 1090 #define OEX_FPU_INEX 0x01 /* Inexact exception. */ 1091 1092 /* Masks for the info word of an ODK_PAD descriptor. */ 1093 #define OPAD_PREFIX 0x01 1094 #define OPAD_POSTFIX 0x02 1095 #define OPAD_SYMBOL 0x04 1096 1097 /* Masks for the info word of an ODK_HWPATCH descriptor. */ 1098 #define OHW_R4KEOP 0x00000001 /* R4000 end-of-page patch. */ 1099 #define OHW_R8KPFETCH 0x00000002 /* May need R8000 prefetch patch. */ 1100 #define OHW_R5KEOP 0x00000004 /* R5000 end-of-page patch. */ 1101 #define OHW_R5KCVTL 0x00000008 /* R5000 cvt.[ds].l bug 1102 (clean == 1). */ 1103 #define OHW_R10KLDL 0x00000010 /* Needs R10K misaligned 1104 load patch. */ 1105 1106 /* Masks for the info word of an ODK_IDENT/ODK_GP_GROUP descriptor. */ 1107 #define OGP_GROUP 0x0000ffff /* GP group number. */ 1108 #define OGP_SELF 0xffff0000 /* Self-contained GP groups. */ 1109 1110 /* Masks for the info word of an ODK_HWAND/ODK_HWOR descriptor. */ 1111 #define OHWA0_R4KEOP_CHECKED 0x00000001 1112 #define OHWA0_R4KEOP_CLEAN 0x00000002 1113 1114 1115 /* Object attribute tags. */ 1116 enum 1117 { 1118 /* 0-3 are generic. */ 1119 Tag_GNU_MIPS_ABI_FP = 4, /* Value 1 for hard-float -mdouble-float, 2 1120 for hard-float -msingle-float, 3 for 1121 soft-float, 4 for -mips32r2 -mfp64; 0 for 1122 not tagged or not using any ABIs affected 1123 by the differences. */ 1124 }; 1125 1126 #endif /* _ELF_MIPS_H */ 1127
