This patchset improves the SH4 emulation by using the lately added TCG instructions, namely add2, sub2 and movcond. For that the T, Q and M bits are split out from the SR register.
The last two patches are doing cleanup in the code. Aurelien Jarno (8): target-sh4: use bit number for SR constants target-sh4: Split out T from SR target-sh4: optimize addc using add2 target-sh4: optimize subc using sub2 target-sh4: optimize negc using add2 and sub2 target-sh4: split out Q and M from of SR and optimize div1 target-sh4: factorize fmov implementation target-sh4: remove dead code target-sh4/cpu.c | 3 +- target-sh4/cpu.h | 51 +++++--- target-sh4/gdbstub.c | 8 +- target-sh4/helper.c | 29 ++--- target-sh4/helper.h | 1 - target-sh4/op_helper.c | 148 +---------------------- target-sh4/translate.c | 316 +++++++++++++++++++++++++----------------------- 7 files changed, 226 insertions(+), 330 deletions(-) -- 1.7.10.4
