Add support for the RISC-V-specific ELF flags
The RISC-V port defines ELF flags that enforce compatibility between various objects. This adds the shared support necessary for these flags. 2018-01-25 Palmer Dabbelt <palmer@sifive.com> * elf/cache.c (print_entry): Add FLAG_RISCV_FLOAT_ABI_SOFT and FLAG_RISCV_FLOAT_ABI_DOUBLE. * elf/elf.h (EF_RISCV_RVC): New define. (EF_RISCV_FLOAT_ABI): Likewise. (EF_RISCV_FLOAT_ABI_SOFT): Likewise. (EF_RISCV_FLOAT_ABI_SINGLE): Likewise. (EF_RISCV_FLOAT_ABI_DOUBLE): Likewise. (EF_RISCV_FLOAT_ABI_QUAD): Likewise. * sysdeps/generic/ldconfig.h (FLAG_RISCV_FLOAT_ABI_SOFT): New define. (FLAG_RISCV_FLOAT_ABI_DOUBLE): Likewise.
