That's usually the case nowadays. It seems all TCG related part are already well optimized, and that most targets are now limited by the MMU emulation. That said I agree it makes sense, and also makes the code cleaner (even if bigger). > > r~ > > > Richard Henderson (3): > target-alpha: Use separate TCGv temporaries for the shadow registers > target-alpha: Inline call_pal > target-alpha: Inline hw_ret > > target-alpha/cpu.h | 3 +- > target-alpha/gdbstub.c | 4 +- > target-alpha/helper.c | 63 ++++++--------- > target-alpha/helper.h | 3 - > target-alpha/machine.c | 4 +- > target-alpha/sys_helper.c | 22 ----- > target-alpha/translate.c | 201 > ++++++++++++++++++++++++++++++---------------- > 7 files changed, 166 insertions(+), 134 deletions(-) The whole series is: Reviewed-by: Aurelien Jarno <aurel...@aurel32.net> -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurel...@aurel32.net http://www.aurel32.net
