disas: Rename include/disas/bfd.h back to include/disas/dis-asm.h Commit dc99065b5f9 (v0.1.0) added dis-asm.h from binutils. Commit 43d4145a986 (v0.1.5) inlined bfd.h into dis-asm.h to remove the dependency on binutils. Commit 76cad71136b (v1.4.0) moved dis-asm.h to include/disas/bfd.h. The new name is confusing when you try to match against (pre GPLv3+) binutils. Rename it back. Keep it in the same directory, of course.

riscv: Add support for the Zfa extension This patch introduces the RISC-V Zfa extension, which introduces additional floating-point instructions: * fli (load-immediate) with pre-defined immediates * fminm/fmaxm (like fmin/fmax but with different NaN behaviour) * fround/froundmx (round to integer) * fcvtmod.w.d (Modular Convert-to-Integer) * fmv* to access high bits of float register bigger than XLEN * Quiet comparison instructions (fleq/fltq) Zfa defines its instructions in combination with the following extensions: * single-precision floating-point (F) * double-precision floating-point (D) * quad-precision floating-point (Q) * half-precision floating-point (Zfh) Since QEMU does not support the RISC-V quad-precision floating-point ISA extension (Q), this patch does not include the instructions that depend on this extension. All other instructions are included in this patch. The Zfa specification can be found here: https://github.com/riscv/riscv-isa-manual/blob/master/src/zfa.tex The Zfa specifciation is frozen and is in public review since May 3, 2023: https://groups.google.com/a/groups.riscv.org/g/isa-dev/c/SED4ntBkabg The patch also includes a TCG test for the fcvtmod.w.d instruction. The test cases test for correct results and flag behaviour. Note, that the Zfa specification requires fcvtmod's flag behaviour to be identical to a fcvt with the same operands (which is also tested).

disas/riscv: Encapsulate opcode_data into decode This patch adds a reference to a struct rv_opcode_data object into struct rv_decode. This further allows to remove all references to the global variable opcode_data (which is renamed to rvi_opcode_data). This patch does not introduce any functional change, but prepares the code for more struct rv_opcode_data objects in the future. This patch is based on previous work from Liu Zhiwei: https://lists.nongnu.org/archive/html/qemu-devel/2022-08/msg03662.html Co-developed-by: LIU Zhiwei <zhiwei_liu@linux.alibaba.com> Reviewed-by: Alistair Francis <alistair.francis@wdc.com> Signed-off-by: Christoph Müllner <christoph.muellner@vrull.eu> Message-Id: <20230612111034.3955227-6-christoph.muellner@vrull.eu> Signed-off-by: Alistair Francis <alistair.francis@wdc.com>

riscv/disas: Fix disas output of upper immediates The GNU assembler produces the following output for instructions with upper immediates: 00002597 auipc a1,0x2 000024b7 lui s1,0x2 6409 lui s0,0x2 # c.lui The immediate operands of upper immediates are not shifted. However, the QEMU disassembler prints them shifted: 00002597 auipc a1,8192 000024b7 lui s1,8192 6409 lui s0,8192 # c.lui The current implementation extracts the immediate bits and shifts the by 12, so the internal representation of the immediate is the actual immediate. However, the immediates are later printed using rv_fmt_rd_imm or rv_fmt_rd_offset, which don't undo the shift. Let's fix this by using specific output formats for instructions with upper immediates, that take care of the shift.

riscv/disas: Fix disas output of upper immediates The GNU assembler produces the following output for instructions with upper immediates: 00002597 auipc a1,0x2 000024b7 lui s1,0x2 6409 lui s0,0x2 # c.lui The immediate operands of upper immediates are not shifted. However, the QEMU disassembler prints them shifted: 00002597 auipc a1,8192 000024b7 lui s1,8192 6409 lui s0,8192 # c.lui The current implementation extracts the immediate bits and shifts the by 12, so the internal representation of the immediate is the actual immediate. However, the immediates are later printed using rv_fmt_rd_imm or rv_fmt_rd_offset, which don't undo the shift. Let's fix this by using specific output formats for instructions with upper immediates, that take care of the shift.

disas/riscv.c: Remove unused decomp_rv32/64 value for vector instructions Currently decomp_rv32 and decomp_rv64 value in opcode_data for vector instructions are the same op index as their own. And they have no functional decomp_data. So they have no functional difference from just leaving them as zero.

riscv: Add support for the Zfa extension This patch introduces the RISC-V Zfa extension, which introduces additional floating-point instructions: * fli (load-immediate) with pre-defined immediates * fminm/fmaxm (like fmin/fmax but with different NaN behaviour) * fround/froundmx (round to integer) * fcvtmod.w.d (Modular Convert-to-Integer) * fmv* to access high bits of float register bigger than XLEN * Quiet comparison instructions (fleq/fltq) Zfa defines its instructions in combination with the following extensions: * single-precision floating-point (F) * double-precision floating-point (D) * quad-precision floating-point (Q) * half-precision floating-point (Zfh) Since QEMU does not support the RISC-V quad-precision floating-point ISA extension (Q), this patch does not include the instructions that depend on this extension. All other instructions are included in this patch. The Zfa specification can be found here: https://github.com/riscv/riscv-isa-manual/blob/master/src/zfa.tex The Zfa specifciation is frozen and is in public review since May 3, 2023: https://groups.google.com/a/groups.riscv.org/g/isa-dev/c/SED4ntBkabg The patch also includes a TCG test for the fcvtmod.w.d instruction. The test cases test for correct results and flag behaviour. Note, that the Zfa specification requires fcvtmod's flag behaviour to be identical to a fcvt with the same operands (which is also tested).

disas/riscv: Support zcmop disassemble Although in QEMU disassemble, we usually lift compressed instruction to an normal format when display the instruction name. For C.MOP.n, it is more reasonable to directly display its compressed name, because its behavior can be redefined by later extension.

riscv: Add support for the Zfa extension This patch introduces the RISC-V Zfa extension, which introduces additional floating-point instructions: * fli (load-immediate) with pre-defined immediates * fminm/fmaxm (like fmin/fmax but with different NaN behaviour) * fround/froundmx (round to integer) * fcvtmod.w.d (Modular Convert-to-Integer) * fmv* to access high bits of float register bigger than XLEN * Quiet comparison instructions (fleq/fltq) Zfa defines its instructions in combination with the following extensions: * single-precision floating-point (F) * double-precision floating-point (D) * quad-precision floating-point (Q) * half-precision floating-point (Zfh) Since QEMU does not support the RISC-V quad-precision floating-point ISA extension (Q), this patch does not include the instructions that depend on this extension. All other instructions are included in this patch. The Zfa specification can be found here: https://github.com/riscv/riscv-isa-manual/blob/master/src/zfa.tex The Zfa specifciation is frozen and is in public review since May 3, 2023: https://groups.google.com/a/groups.riscv.org/g/isa-dev/c/SED4ntBkabg The patch also includes a TCG test for the fcvtmod.w.d instruction. The test cases test for correct results and flag behaviour. Note, that the Zfa specification requires fcvtmod's flag behaviour to be identical to a fcvt with the same operands (which is also tested).

riscv: Add support for the Zfa extension This patch introduces the RISC-V Zfa extension, which introduces additional floating-point instructions: * fli (load-immediate) with pre-defined immediates * fminm/fmaxm (like fmin/fmax but with different NaN behaviour) * fround/froundmx (round to integer) * fcvtmod.w.d (Modular Convert-to-Integer) * fmv* to access high bits of float register bigger than XLEN * Quiet comparison instructions (fleq/fltq) Zfa defines its instructions in combination with the following extensions: * single-precision floating-point (F) * double-precision floating-point (D) * quad-precision floating-point (Q) * half-precision floating-point (Zfh) Since QEMU does not support the RISC-V quad-precision floating-point ISA extension (Q), this patch does not include the instructions that depend on this extension. All other instructions are included in this patch. The Zfa specification can be found here: https://github.com/riscv/riscv-isa-manual/blob/master/src/zfa.tex The Zfa specifciation is frozen and is in public review since May 3, 2023: https://groups.google.com/a/groups.riscv.org/g/isa-dev/c/SED4ntBkabg The patch also includes a TCG test for the fcvtmod.w.d instruction. The test cases test for correct results and flag behaviour. Note, that the Zfa specification requires fcvtmod's flag behaviour to be identical to a fcvt with the same operands (which is also tested).

riscv: Add support for the Zfa extension This patch introduces the RISC-V Zfa extension, which introduces additional floating-point instructions: * fli (load-immediate) with pre-defined immediates * fminm/fmaxm (like fmin/fmax but with different NaN behaviour) * fround/froundmx (round to integer) * fcvtmod.w.d (Modular Convert-to-Integer) * fmv* to access high bits of float register bigger than XLEN * Quiet comparison instructions (fleq/fltq) Zfa defines its instructions in combination with the following extensions: * single-precision floating-point (F) * double-precision floating-point (D) * quad-precision floating-point (Q) * half-precision floating-point (Zfh) Since QEMU does not support the RISC-V quad-precision floating-point ISA extension (Q), this patch does not include the instructions that depend on this extension. All other instructions are included in this patch. The Zfa specification can be found here: https://github.com/riscv/riscv-isa-manual/blob/master/src/zfa.tex The Zfa specifciation is frozen and is in public review since May 3, 2023: https://groups.google.com/a/groups.riscv.org/g/isa-dev/c/SED4ntBkabg The patch also includes a TCG test for the fcvtmod.w.d instruction. The test cases test for correct results and flag behaviour. Note, that the Zfa specification requires fcvtmod's flag behaviour to be identical to a fcvt with the same operands (which is also tested).

The Zfa specification can be found here: https://github.com/riscv/riscv-isa-manual/blob/master/src/zfa.tex The Zfa specifciation is frozen and is in public review since May 3, 2023: https://groups.google.com/a/groups.riscv.org/g/isa-dev/c/SED4ntBkabg The patch also includes a TCG test for the fcvtmod.w.d instruction. The test cases test for correct results and flag behaviour. Note, that the Zfa specification requires fcvtmod's flag behaviour to be identical to a fcvt with the same operands (which is also tested).

disas/riscv: Encapsulate opcode_data into decode This patch adds a reference to a struct rv_opcode_data object into struct rv_decode. This further allows to remove all references to the global variable opcode_data (which is renamed to rvi_opcode_data). This patch does not introduce any functional change, but prepares the code for more struct rv_opcode_data objects in the future.

riscv: Add support for the Zfa extension This patch introduces the RISC-V Zfa extension, which introduces additional floating-point instructions: * fli (load-immediate) with pre-defined immediates * fminm/fmaxm (like fmin/fmax but with different NaN behaviour) * fround/froundmx (round to integer) * fcvtmod.w.d (Modular Convert-to-Integer) * fmv* to access high bits of float register bigger than XLEN * Quiet comparison instructions (fleq/fltq) Zfa defines its instructions in combination with the following extensions: * single-precision floating-point (F) * double-precision floating-point (D) * quad-precision floating-point (Q) * half-precision floating-point (Zfh) Since QEMU does not support the RISC-V quad-precision floating-point ISA extension (Q), this patch does not include the instructions that depend on this extension. All other instructions are included in this patch. The Zfa specification can be found here: https://github.com/riscv/riscv-isa-manual/blob/master/src/zfa.tex The Zfa specifciation is frozen and is in public review since May 3, 2023: https://groups.google.com/a/groups.riscv.org/g/isa-dev/c/SED4ntBkabg The patch also includes a TCG test for the fcvtmod.w.d instruction. The test cases test for correct results and flag behaviour. Note, that the Zfa specification requires fcvtmod's flag behaviour to be identical to a fcvt with the same operands (which is also tested).

riscv: Add support for the Zfa extension This patch introduces the RISC-V Zfa extension, which introduces additional floating-point instructions: * fli (load-immediate) with pre-defined immediates * fminm/fmaxm (like fmin/fmax but with different NaN behaviour) * fround/froundmx (round to integer) * fcvtmod.w.d (Modular Convert-to-Integer) * fmv* to access high bits of float register bigger than XLEN * Quiet comparison instructions (fleq/fltq) Zfa defines its instructions in combination with the following extensions: * single-precision floating-point (F) * double-precision floating-point (D) * quad-precision floating-point (Q) * half-precision floating-point (Zfh) Since QEMU does not support the RISC-V quad-precision floating-point ISA extension (Q), this patch does not include the instructions that depend on this extension. All other instructions are included in this patch. The Zfa specification can be found here: https://github.com/riscv/riscv-isa-manual/blob/master/src/zfa.tex The Zfa specifciation is frozen and is in public review since May 3, 2023: https://groups.google.com/a/groups.riscv.org/g/isa-dev/c/SED4ntBkabg The patch also includes a TCG test for the fcvtmod.w.d instruction. The test cases test for correct results and flag behaviour. Note, that the Zfa specification requires fcvtmod's flag behaviour to be identical to a fcvt with the same operands (which is also tested).
