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 fpu/softfloat-specialize.inc.c | 276 +- fpu/softfloat.c | 2 +- include/fpu/softfloat-helpers.h | 10 + include/fpu/softfloat-types.h | 2 + target/xtensa/Makefile.objs | 2 + target/xtensa/core-DE_233L_FPU.c | 31 + target/xtensa/core-DE_233L_FPU/core-isa.h | 727 + target/xtensa/core-DE_233L_FPU/core-matmap.h | 717 + .../xtensa/core-DE_233L_FPU/gdb-config.inc.c | 277 + .../core-DE_233L_FPU/xtensa-modules.inc.c | 20758 ++ target/xtensa/core-dsp3400.c | 31 + target/xtensa/core-dsp3400/core-isa.h | 452 + target/xtensa/core-dsp3400/core-matmap.h | 312 + target/xtensa/core-dsp3400/gdb-config.inc.c | 400 + .../xtensa/core-dsp3400/xtensa-modules.inc.c | 171906 +++++++++++++++ target/xtensa/cpu.c | 4 + target/xtensa/cpu.h | 7 +- target/xtensa/fpu_helper.c | 314 +- target/xtensa/helper.c | 4 +- target/xtensa/helper.h | 53 +- target/xtensa/overlay_tool.h | 6 + target/xtensa/translate.c | 1345 +- tests/tcg/xtensa/fpu.h | 142 + tests/tcg/xtensa/macros.inc | 10 +- tests/tcg/xtensa/test_dfp0_arith.S | 153 + tests/tcg/xtensa/test_fp0_arith.S | 266 +- tests/tcg/xtensa/test_fp0_conv.S | 299 +- tests/tcg/xtensa/test_fp0_div.S | 82 + tests/tcg/xtensa/test_fp0_sqrt.S | 76 + tests/tcg/xtensa/test_fp1.S | 62 +- tests/tcg/xtensa/test_lsc.S | 170 +- 31 files changed, 198354 insertions(+), 542 deletions(-) create mode 100644 target/xtensa/core-DE_233L_FPU.c create mode 100644 target/xtensa/core-DE_233L_FPU/core-isa.h create mode 100644 target/xtensa/core-DE_233L_FPU/core-matmap.h create mode 100644 target/xtensa/core-DE_233L_FPU/gdb-config.inc.c create mode 100644 target/xtensa/core-DE_233L_FPU/xtensa-modules.inc.c create mode 100644 target/xtensa/core-dsp3400.c create mode 100644 target/xtensa/core-dsp3400/core-isa.h create mode 100644 target/xtensa/core-dsp3400/core-matmap.h create mode 100644 target/xtensa/core-dsp3400/gdb-config.inc.c create mode 100644 target/xtensa/core-dsp3400/xtensa-modules.inc.c create mode 100644 tests/tcg/xtensa/fpu.h create mode 100644 tests/tcg/xtensa/test_dfp0_arith.S create mode 100644 tests/tcg/xtensa/test_fp0_div.S create mode 100644 tests/tcg/xtensa/test_fp0_sqrt.S -- 2.20.1
