This series implements floating point coprocessor and coprocessor context options for xtensa and fixes a couple of bugs to make it work.
Changes v1->v2: - add NO_SIGNALING_NANS and drop float32_maybe_silence_nan specialization - fix fp registers access in gdbstub - replace float32_mul/div in FP-to-integer convertors with float32_scalbn - reimplement comparison with zero in FP-to-integer convertors Max Filippov (10): softfloat: make float_muladd_negate_* flags independent softfloat: add NO_SIGNALING_NANS target-xtensa: handle boolean option in overlays target-xtensa: specialize softfloat NaN rules target-xtensa: add FP registers target-xtensa: implement LSCX and LSCI groups target-xtensa: implement FP0 arithmetic target-xtensa: implement FP0 conversions target-xtensa: implement FP1 group target-xtensa: implement coprocessor context option fpu/softfloat-specialize.h | 69 +++++++++- fpu/softfloat.h | 7 +- gdbstub.c | 8 + target-xtensa/cpu.h | 8 + target-xtensa/helper.h | 21 +++ target-xtensa/op_helper.c | 134 +++++++++++++++++ target-xtensa/overlay_tool.h | 1 + target-xtensa/translate.c | 338 ++++++++++++++++++++++++++++++++++++++++-- 8 files changed, 570 insertions(+), 16 deletions(-) -- 1.7.7.6
