CSKY: Add FPUV3 instructions, which supported by ck860f.
Co-Authored-By: Lifang Xia <lifang_xia@c-sky.com>
gas/
* config/tc-csky.c (float_work_fpuv3_fmovi): New function,
helper function to encode fpuv3 fmovi instructions.
(float_work_fpuv3_fstore): New function.
(struct literal): Add new member 'offset'.
(csky_cpus): New cpu CK860f.
(enter_literal): Return literal pool pointer instead of offset.
(parse_rt): Adjust the change of enter_literal.
(parse_rtf): Likewise.
(v1_work_lrw): Likewise.
(v1_work_jbsr): Likewise.
(v2_work_lrw): Likewise.
(v2_work_jbsr): Likewise.
(v2_work_jsri): Likewise.
(vdsp_work_vlrw): Likewise.
(is_freglist_legal): Add handler for FPUV3.
(parse_type_freg): Likewise.
(is_imm_within_range): Set e.X_add_number if it is a signed and
negtive number.
(get_operand_value): Add handler for OPRND_TYPE_IMM9b,
OPRND_TYPE_HFLOAT_FMOVI, OPRND_TYPE_SFLOAT_FMOVI
and OPRND_TYPE_DFLOAT_FMOVI.
(float_to_half): Convert float number to harf float.
opcodes/
* csky-dis.c (csky_output_operand): Add handlers for
OPRND_TYPE_HFLOAT_FMOVI, OPRND_TYPE_SFLOAT_FMOVI and
OPRND_TYPE_DFLOAT_FMOVI. Refine OPRND_TYPE_FREGLIST_DASH
to support FPUV3 instructions.
* csky-opc.h (enum operand_type): New enum OPRND_TYPE_IMM9b,
OPRND_TYPE_HFLOAT_FMOVI, OPRND_TYPE_SFLOAT_FMOVI and
OPRND_TYPE_DFLOAT_FMOVI.
