target-sh4: switch to AREG0 free mode Add an explicit CPUState parameter instead of relying on AREG0 and switch to AREG0 free mode. Acked-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

DEF_HELPER_1(ldtlb, void, env)
target-sh4: rework exceptions handling Since commit fd4bab102 PC is restored in case of exception through code retranslation. While it is clearly the thing to do in case it is not not known if an helper is going to trigger an exception or not (e.g. for load/store, FPU, etc.), it just make things slower when the exception is already known at translation time. Partially revert this commit and save PC in the TCG code. Set bstate to BS_BRANCH to not generate TCG exit code. Micro-optimize the sleep helper. Make all the exception helpers to call raise_exception and mark it as noreturn. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

SH: Improve movca.l/ocbi emulation. Author: Vladimir Prus <vladimir@codesourcery.com> Fix movcal.l/ocbi emulation. * target-sh4/cpu.h (memory_content): New. (CPUSH4State): New fields movcal_backup and movcal_backup_tail. * target-sh4/helper.h (helper_movcal) (helper_discard_movcal_backup, helper_ocbi): New. * target-sh4/op_helper.c (helper_movcal) (helper_discard_movcal_backup, helper_ocbi): New. * target-sh4/translate.c (DisasContext): New field has_movcal. (sh4_defs): Update CVS for SH7785. (cpu_sh4_init): Initialize env->movcal_backup_tail. (_decode_opc): Discard movca.l-backup. Make use of helper_movcal and helper_ocbi. (gen_intermediate_code_internal): Initialize has_movcal to 1. Thanks to Shin-ichiro KAWASAKI and Paul Mundt for valuable feedback. Acked-by: Edgar E.
