2023-07-19riscv/disas: Fix disas output of upper immediatesChristoph Müllner
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.

2023-07-10riscv: Add support for the Zfa extensionChristoph Müllner
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).

2023-06-20meson: Replace softmmu_ss -> system_ssPhilippe Mathieu-Daudé
We use the user_ss[] array to hold the user emulation sources, and the softmmu_ss[] array to hold the system emulation ones. Hold the latter in the 'system_ss[]' array for parity with user emulation. Mechanical change doing: $ sed -i -e s/softmmu_ss/system_ss/g $(git grep -l softmmu_ss) Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20230613133347.82210-10-philmd@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

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.
