You can also find the patchset and all *test cases* in my repo(https://github.com/romanheros/qemu.git branch:vector-upstream-v8). All the test cases are in the directory qemu/tests/riscv/vector/. They are riscv64 linux user mode programs. You can test the patchset by the script qemu/tests/riscv/vector/runcase.sh. Features: * support specification riscv-v-spec-0.7.1.(https://github.com/riscv/riscv-v-spec/releases/tag/0.7.1/) * support basic vector extension. * support Zvlsseg. * support Zvamo. * not support Zvediv as it is changing. * SLEN always equals VLEN. * element width support 8bit, 16bit, 32bit, 64bit. Changelog: v8 * support different float rounding modes for vector instructions. * use lastest released TCG GVEC DUP IR. * set RV_VLEN_MAX to 256 bits, as GVEC IR uses simd_desc. v7 * move vl == 0 check to translation time by add a global cpu_vl. * implement vector element inline load and store function by TCG IR. * based on vec_element_load(store), implement some permutation instructions. * implement rsubs GVEC IR. * fixup vsmul, vmfne, vfmerge, vslidedown. * some other small bugs and indentation errors. v6 * use gvec_dup Gvec IR to accellerate move and merge. * a better way to implement fixed point instructions. * a global check when vl == 0. * limit some macros to only one inline function call. * fixup sew error when use Gvec IR. * fixup bugs for corner cases. v5 * fixup a bug in tb flags. v4 * no change v3 * move check code from execution-time to translation-time * use a continous memory block for vector register description. * vector registers as direct fields in RISCVCPUState. * support VLEN configure from qemu command line. * support ELEN configure from qemu command line. * support vector specification version configure from qemu command line. * probe pages before real load or store access. * use probe_page_check for no-fault operations in linux user mode. * generation atomic exit exception when in parallel environment. * fixup a lot of concrete bugs. V2 * use float16_compare{_quiet} * only use GETPC() in outer most helper * add ctx.ext_v Property LIU Zhiwei (62): target/riscv: add vector extension field in CPURISCVState target/riscv: implementation-defined constant parameters target/riscv: support vector extension csr target/riscv: add vector configure instruction target/riscv: add an internals.h header target/riscv: add vector stride load and store instructions target/riscv: add vector index load and store instructions target/riscv: add fault-only-first unit stride load target/riscv: add vector amo operations target/riscv: vector single-width integer add and subtract target/riscv: vector widening integer add and subtract target/riscv: vector integer add-with-carry / subtract-with-borrow instructions target/riscv: vector bitwise logical instructions target/riscv: vector single-width bit shift instructions target/riscv: vector narrowing integer right shift instructions target/riscv: vector integer comparison instructions target/riscv: vector integer min/max instructions target/riscv: vector single-width integer multiply instructions target/riscv: vector integer divide instructions target/riscv: vector widening integer multiply instructions target/riscv: vector single-width integer multiply-add instructions target/riscv: vector widening integer multiply-add instructions target/riscv: vector integer merge and move instructions target/riscv: vector single-width saturating add and subtract target/riscv: vector single-width averaging add and subtract target/riscv: vector single-width fractional multiply with rounding and saturation target/riscv: vector widening saturating scaled multiply-add target/riscv: vector single-width scaling shift instructions target/riscv: vector narrowing fixed-point clip instructions target/riscv: Update fp_status when float rounding mode changes target/riscv: vector single-width floating-point add/subtract instructions target/riscv: vector widening floating-point add/subtract instructions target/riscv: vector single-width floating-point multiply/divide instructions target/riscv: vector widening floating-point multiply target/riscv: vector single-width floating-point fused multiply-add instructions target/riscv: vector widening floating-point fused multiply-add instructions target/riscv: vector floating-point square-root instruction target/riscv: vector floating-point min/max instructions target/riscv: vector floating-point sign-injection instructions target/riscv: vector floating-point compare instructions target/riscv: vector floating-point classify instructions target/riscv: vector floating-point merge instructions target/riscv: vector floating-point/integer type-convert instructions target/riscv: widening floating-point/integer type-convert instructions target/riscv: narrowing floating-point/integer type-convert instructions target/riscv: vector single-width integer reduction instructions target/riscv: vector wideing integer reduction instructions target/riscv: vector single-width floating-point reduction instructions target/riscv: vector widening floating-point reduction instructions target/riscv: vector mask-register logical instructions target/riscv: vector mask population count vmpopc target/riscv: vmfirst find-first-set mask bit target/riscv: set-X-first mask bit target/riscv: vector iota instruction target/riscv: vector element index instruction target/riscv: integer extract instruction target/riscv: integer scalar move instruction target/riscv: floating-point scalar move instructions target/riscv: vector slide instructions target/riscv: vector register gather instruction target/riscv: vector compress instruction target/riscv: configure and turn on vector extension from command line target/riscv/Makefile.objs | 2 +- target/riscv/cpu.c | 49 + target/riscv/cpu.h | 82 +- target/riscv/cpu_bits.h | 15 + target/riscv/csr.c | 82 +- target/riscv/fpu_helper.c | 52 +- target/riscv/helper.h | 1068 +++++ target/riscv/insn32-64.decode | 11 + target/riscv/insn32.decode | 372 ++ target/riscv/insn_trans/trans_rvv.inc.c | 2884 +++++++++++++ target/riscv/internals.h | 44 + target/riscv/translate.c | 27 +- target/riscv/vector_helper.c | 4898 +++++++++++++++++++++++ 13 files changed, 9537 insertions(+), 49 deletions(-) create mode 100644 target/riscv/insn_trans/trans_rvv.inc.c create mode 100644 target/riscv/internals.h create mode 100644 target/riscv/vector_helper.c
