2023-05-18Hexagon (target/hexagon) Short-circuit more HVX single instruction packetsTaylor Simpson
The generated helpers for HVX use pass-by-reference, so they can't short-circuit when the reads/writes overlap. The instructions with overrides are OK because they use tcg_gen_gvec_*. We add a flag has_hvx_helper to DisasContext and extend gen_analyze_funcs to set the flag when the instruction is an HVX instruction with a generated helper. We add an override for V6_vcombine so that it can be short-circuited along with a test case in tests/tcg/hexagon/hvx_misc.c Signed-off-by: Taylor Simpson <tsimpson@quicinc.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20230427230012.3800327-15-tsimpson@quicinc.com>

2022-12-16Hexagon (target/hexagon) Add pkt and insn to DisasContextTaylor Simpson
This enables us to reduce the number of parameters to many functions In particular, the generated functions previously took all 3 as arguments Not only does this simplify the code, it improves the translation time Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Taylor Simpson <tsimpson@quicinc.com> Message-Id: <20221108162906.3166-2-tsimpson@quicinc.com>
