Hello,
this series implements double precision floating point unit option for
target/xtensa, updates FPU tests and adds two new CPU cores, one with
FPU2000 option and one with DFPU option.
It is tagged xtensa-5.1-dfp-v4 in the qemu-xtensa tree at
git://github.com/OSLL/qemu-xtensa.git
I don't post the last two patches as they are too big for the list,
they can be found in the git tree mentioned above.
Changes v3->v4:
- split DFPU option addition into a separate patch, change DFP unit
detection logic
- avoid calling set_use_first_nan on every FPU operation in FPU2000
and single-precision only DFPU configurations
Changes v2->v3:
- handle infzero case in pickNaNMulAdd properly and reword commit
message
- add more infzero tests for FPU2000 and DFPU
- fix test names in test_dfp0_arith.S
- add licenses to newly imported cores
- rename DE_233L_FPU to de233_fpu to be more consistent with other
core names
Changes v1->v2:
- use inline function for no_signaling_nans property to allow for
constant folding on architectures that have this property fixed.
