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.
