Subject: [PATCH v6 00/61]  target/riscv: support vector extension v0.7.1
Date: Tue, 17 Mar 2020 23:05:52 +0800
Message-ID: <20200317150653.9008-1-zhiwei_liu@c-sky.com> (raw)

This patchset implements the vector extension for RISC-V on QEMU.

You can also find the patchset and all *test cases* in
my repo(https://github.com/romanheros/qemu.git branch:vector-upstream-v3).
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:
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
