[PATCH 00/21] target/xtensa: implement double precision FPU

[Max Filippov]

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.

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
  tests/tcg/xtensa: update test_fp0_arith for DFPU
  tests/tcg/xtensa: expand madd tests
  tests/tcg/xtensa: update test_fp0_conv for DFPU
  tests/tcg/xtensa: update test_fp1 for DFPU
  tests/tcg/xtensa: update test_lsc for DFPU
  tests/tcg/xtensa: add fp0 div and sqrt tests
  tests/tcg/xtensa: test double precision load/store
  tests/tcg/xtensa: add DFP0 arith tests
  target/xtensa: import DE_233L_FPU core
  target/xtensa: import DSP3400 core
