Subject: [PATCH 00/21] target/xtensa: implement double precision FPU
Date: Wed, 8 Jul 2020 15:20:40 -0700 [thread overview]
Message-ID: <20200708222101.24568-1-jcmvbkbc@gmail.com> (raw)
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-v3 in the qemu-xtensa tree at
git://github.com/OSLL/qemu-xtensa.git
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.
Max Filippov (21):
softfloat: make NO_SIGNALING_NANS runtime property
softfloat: pass float_status pointer to pickNaN
softfloat: add xtensa specialization for pickNaNMulAdd
target/xtensa: add geometry to xtensa_get_regfile_by_name
target/xtensa: support copying registers up to 64 bits wide
target/xtensa: rename FPU2000 translators and helpers
target/xtensa: move FSR/FCR register accessors
target/xtensa: don't access BR regfile directly
target/xtensa: add DFP option, registers and opcodes
target/xtensa: implement FPU division and square root
tests/tcg/xtensa: fix test execution on ISS
