Reorg handling of $zero, with different accessors for source and destination. Reorg handling of csrs, passing the actual write_mask instead of a regno. Use more helpers for RVH expansion. Changes for v2: * Retain the requirement to call gen_set_gpr. * Add DisasExtend as an argument to get_gpr, and ctx->w as a member of DisasContext. This should help in implementing UXL, where we should be able to set ctx->w for all insns, but there is certainly more required for that. Because of this, I've dropped most of the r-b from v1. r~ Richard Henderson (21): target/riscv: Use tcg_constant_* target/riscv: Clean up division helpers target/riscv: Add DisasContext to gen_get_gpr, gen_set_gpr target/riscv: Introduce DisasExtend and new helpers target/riscv: Add DisasExtend to gen_arith* target/riscv: Remove gen_arith_div* target/riscv: Use gen_arith for mulh and mulhu target/riscv: Move gen_* helpers for RVM target/riscv: Move gen_* helpers for RVB target/riscv: Add DisasExtend to gen_unary target/riscv: Use DisasExtend in shift operations target/riscv: Add gen_greviw target/riscv: Use get_gpr in branches target/riscv: Use {get,dest}_gpr for integer load/store target/riscv: Reorg csr instructions target/riscv: Use {get,dest}_gpr for RVA target/riscv: Use gen_shift_imm_fn for slli_uw target/riscv: Use {get,dest}_gpr for RVF target/riscv: Use {get,dest}_gpr for RVD target/riscv: Tidy trans_rvh.c.inc target/riscv: Use {get,dest}_gpr for RVV target/riscv/helper.h | 6 +- target/riscv/insn32.decode | 1 + target/riscv/op_helper.c | 18 +- target/riscv/translate.c | 702 +++++------------------- target/riscv/insn_trans/trans_rva.c.inc | 51 +- target/riscv/insn_trans/trans_rvb.c.inc | 382 ++++++++++--- target/riscv/insn_trans/trans_rvd.c.inc | 127 ++--- target/riscv/insn_trans/trans_rvf.c.inc | 149 +++-- target/riscv/insn_trans/trans_rvh.c.inc | 266 ++------- target/riscv/insn_trans/trans_rvi.c.inc | 360 ++++++------ target/riscv/insn_trans/trans_rvm.c.inc | 176 ++++-- target/riscv/insn_trans/trans_rvv.c.inc | 151 ++--- 12 files changed, 1058 insertions(+), 1331 deletions(-)
