Make the opcode/riscv-opc.c and include/opcode/riscv.h tidy, move the
spec versions stuff to bfd/cpu-riscv.h. Also move the csr stuff and
ext_version_table to gas/config/tc-riscv.c for internal use. To avoid
too many repeated code, define general RISCV_GET_SPEC_NAME/SPEC_CLASS
macros. Therefore, assembler/dis-assembler/linker/gdb can get all spec
versions related stuff from cpu-riscv.h and cpu-riscv.c, since the stuff
are defined there uniformly.
bfd/
* Makefile.am: Added cpu-riscv.h.
* Makefile.in: Regenerated.
* po/SRC-POTFILES.in: Regenerated.
* cpu-riscv.h: Added to support spec versions controlling.
Also added extern arrays and functions for cpu-riscv.c.
(enum riscv_spec_class): Define all spec classes here uniformly.
(struct riscv_spec): Added for all specs.
(RISCV_GET_SPEC_CLASS): Added to reduce repeated code.
(RISCV_GET_SPEC_NAME): Likewise.
(RISCV_GET_ISA_SPEC_CLASS): Added to get ISA spec class.
(RISCV_GET_PRIV_SPEC_CLASS): Added to get privileged spec class.
(RISCV_GET_PRIV_SPEC_NAME): Added to get privileged spec name.
* cpu-riscv.c (struct priv_spec_t): Replaced with struct riscv_spec.
(riscv_get_priv_spec_class): Replaced with RISCV_GET_PRIV_SPEC_CLASS.
(riscv_get_priv_spec_name): Replaced with RISCV_GET_PRIV_SPEC_NAME.
(riscv_priv_specs): Moved below.
(riscv_get_priv_spec_class_from_numbers): Likewise, updated.
(riscv_isa_specs): Moved from include/opcode/riscv.h.
* elfnn-riscv.c: Included cpu-riscv.h.
(riscv_merge_attributes): Initialize in_priv_spec and out_priv_spec.
* elfxx-riscv.c: Included cpu-riscv.h and opcode/riscv.h.
(RISCV_UNKNOWN_VERSION): Moved from include/opcode/riscv.h.
* elfxx-riscv.h: Removed extern functions to cpu-riscv.h.
gas/
* config/tc-riscv.c: Included cpu-riscv.h.
(enum riscv_csr_clas): Moved from include/opcode/riscv.h.
(struct riscv_csr_extra): Likewise.
(struct riscv_ext_version): Likewise.
(ext_version_table): Moved from opcodes/riscv-opc.c.
(default_isa_spec): Updated type to riscv_spec_class.
(default_priv_spec): Likewise.
(riscv_set_default_isa_spec): Updated.
(init_ext_version_hash): Likewise.
(riscv_init_csr_hash): Likewise, also fixed indent.
include/
* opcode/riscv.h: Moved stuff and make the file tidy.
opcodes/
* riscv-dis.c: Included cpu-riscv.h, and removed elfxx-riscv.h.
(default_priv_spec): Updated type to riscv_spec_class.
(parse_riscv_dis_option): Updated.
* riscv-opc.c: Moved stuff and make the file tidy.
