This patch series try to improve the SH4 target by using the (more or less) recently introduced TCG features. It also fixes some issues spot when writting the patches (linking of TB with different flags, SH4-A specific instructions allowed on SH4) and correctly trap unaligned accesses.
v3: - Use extr instead of extrh/extrl in gen_store_fpr64, as suggested by Richard Henderson - Use cpu_loop_exit_restore instead of cpu_loop_exit/cpu_restore_state in superh_cpu_do_unaligned_access - Add a patch to convert the remaining cpu_loop_exit/cpu_restore_state to cpu_loop_exit_restore - Add Reviewed-by entries v2: - Add some comments in the struct DisasContext declaration, as suggested by Philippe Mathieu-Daudé Aurelien Jarno (15): target/sh4: split ctx->flags into ctx->tbflags and ctx->envflags target/sh4: get rid of DELAY_SLOT_CLEARME target/sh4: do not include DELAY_SLOT_TRUE in the TB state target/sh4: move DELAY_SLOT_TRUE flag into a separate global target/sh4: fix BS_STOP exit target/sh4: fix BS_EXCP exit target/sh4: only save flags state at the end of the TB target/sh4: fold ctx->bstate = BS_BRANCH into gen_conditional_jump target/sh4: optimize gen_store_fpr64 target/sh4: optimize gen_write_sr using extract op target/sh4: generate fences for SH4 target/sh4: implement tas.b using atomic helper target/sh4: movua.l is an SH4-A only instruction target/sh4: trap unaligned accesses target/sh4: use cpu_loop_exit_restore target/sh4/cpu.c | 1 + target/sh4/cpu.h | 18 ++- target/sh4/helper.c | 4 +- target/sh4/op_helper.c | 26 ++-- target/sh4/translate.c | 322 +++++++++++++++++++++++-------------------------- 5 files changed, 181 insertions(+), 190 deletions(-) -- 2.11.0
