RRichard Hendersontcg/sparc64: Implement tcg_out_extrl_i64_i32

tcg/sparc64: Use standard slow path for softmmu Drop the target-specific trampolines for the standard slow path. This lets us use tcg_out_helper_{ld,st}_args, and handles the new atomicity bits within MemOp. At the same time, use the full load/store helpers for user-only mode. Drop inline unaligned access support for user-only mode, as it does not handle atomicity. Use TCG_REG_T[1-3] in the tlb lookup, instead of TCG_REG_O[0-2]. This allows the constraints to be simplified. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org> | 3 年前 | |

tcg: Split out tcg-target-reg-bits.h Often, the only thing we need to know about the TCG host is the register size. Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org> | 3 年前 | |
