from glibc (and binutils), I have: /* RISC-V ELF Flags */ #define EF_RISCV_RVC 0x0001 #define EF_RISCV_FLOAT_ABI 0x0006 #define EF_RISCV_FLOAT_ABI_SOFT 0x0000 #define EF_RISCV_FLOAT_ABI_SINGLE 0x0002 #define EF_RISCV_FLOAT_ABI_DOUBLE 0x0004 #define EF_RISCV_FLOAT_ABI_QUAD 0x0006 Perhaps you can also define EF_RISCV_FLOAT_ABI_SOFT and EF_RISCV_FLOAT_ABI?
