Specification: https://github.com/riscv/riscv-code-size-reduction/tree/main/Zc-specification The port is available here: https://github.com/plctlab/plct-qemu/tree/plct-zce-upstream-v11 To test Zc* implementation, specify cpu argument with 'x-zca=true,x-zcb=true,x-zcf=true,f=true" and "x-zcd=true,d=true" (or "x-zcmp=true,x-zcmt=true" with c or d=false) to enable Zca/Zcb/Zcf and Zcd(or Zcmp,Zcmt) extensions support. This implementation can pass the basic zc tests from https://github.com/yulong-plct/zc-test v11 * update format and field name based on the latest spec in patch 5, 6, 7 (without other functional changes) * rebase on riscv-to-apply.next v10: * rebase on Daniel's series(riscv-to-apply.next) and adjust riscv-tests to test on sifive related CPUs v9: * rebase on riscv-to-apply.next v8: * improve disas support in Patch 9 v7: * Fix description for Zca v6： * fix base address for jump table in Patch 7 * rebase on riscv-to-apply.next v5: * fix exception unwind problem for cpu_ld*_code in helper of cm_jalt v4: * improve Zcmp suggested by Richard * fix stateen related check for Zcmt v3: * update the solution for Zcf to the way of Zcd * update Zcb to reuse gen_load/store * use trans function instead of helper for push/pop v2: * add check for relationship between Zca/Zcf/Zcd with C/F/D based on related discussion in review of Zc* spec * separate c.fld{sp}/fsd{sp} with fld{sp}/fsd{sp} before support of zcmp/zcmt Weiwei Li (9): target/riscv: add cfg properties for Zc* extension target/riscv: add support for Zca extension target/riscv: add support for Zcf extension target/riscv: add support for Zcd extension target/riscv: add support for Zcb extension target/riscv: add support for Zcmp extension target/riscv: add support for Zcmt extension target/riscv: expose properties for Zc* extension disas/riscv.c: add disasm support for Zc* disas/riscv.c | 228 +++++++++++++++- target/riscv/cpu.c | 56 ++++ target/riscv/cpu.h | 10 + target/riscv/cpu_bits.h | 7 + target/riscv/csr.c | 38 ++- target/riscv/helper.h | 3 + target/riscv/insn16.decode | 62 ++++- target/riscv/insn_trans/trans_rvd.c.inc | 18 ++ target/riscv/insn_trans/trans_rvf.c.inc | 18 ++ target/riscv/insn_trans/trans_rvi.c.inc | 4 +- target/riscv/insn_trans/trans_rvzce.c.inc | 313 ++++++++++++++++++++++ target/riscv/machine.c | 19 ++ target/riscv/meson.build | 3 +- target/riscv/translate.c | 15 +- target/riscv/zce_helper.c | 55 ++++ 15 files changed, 833 insertions(+), 16 deletions(-) create mode 100644 target/riscv/insn_trans/trans_rvzce.c.inc create mode 100644 target/riscv/zce_helper.c
