mechanism is starting to subside.
* sky-pke.h (PKE_FLAG_INT_NOLOOP): Added device flag to indicate
presence of stalled & interrupted PKEcode.
* sky-pke.c (pke_issue): Added PKEcode interrupt bit handling.
(pke_flip_dbf): Changed double-buffering logic to match SCEI
clarification.
(pke_code_*): Added interrupt bit stalling clause.
(pke_code_pkems*): Added ITOP/ITOPS transmission code.
(pke_code_unpack): Added more careful logic for processing
overflows of VU data memory addresses.
(engine_resume_full): Keep accurate core profile data.
* cgen-utils.c (sim_disassemble_insn): Don't use
sim_core_read_aligned_N, it messes up profiling results.
* sky-pke.h (PKE_MEM_READ): Removed "read" entry from FIFO trace.
* sky-pke.c (pke_attach): Set trace file to line buffering iff
open.
(pke_io_read_buffer, pke_io_write_buffer): Handle erroneous
reads/writes by zero-padding.
(pke_io_write_buffer): Switch to more bit-field definition macros.
(pke_issue): Remove "stalled" entry from FIFO trace.
(pke_pc_advance): Correct logic for DMA-tag-skipping, PKEcode
classification.
(pke_code_mskpath3): Sketch of possible PATH3 masking method.
(pke_code_mpg): Keep order of lower/upper VU words as supplied.
(pke_code_unpack): Logic change for wl/cl/num unpacking. Weird.
little struct.
interp.c: Update. Also add floating point Max/Min functions.
mips.igen: Remove r5900 tag from any floating point instructions.
r5900.igen: Rewrite. Implement *all* floating point insns (except ld/st).
r5400.igen: Tag mdmx functions as being mdmx specific.
discarded function warning.
* igen.c (main): Clarify -Wnodiscard.
* ld-insn.c (parse_function_record): For functions, allow use of
instruction style function model records
were hammered in today's runs. Work is beginning in endian-proofing
the code.
* sky-pke.c (pke1_issue): Issue on correct PKE device.
(pke_io_write_buffer, pke_code_mpg, pke_code_unpack): Perform more
endian conversions.
(pke_code_mpg, pke_code_direct): Add operand alignment assertions.
(pke_code_mpg): Correct VU stall checks. Correct VU opcode
transfer ordering.
(pke_code_direct): Correct typos in DIRECT operand accessing.
(pke_code_unpack): Correct conditional sign-extension handling.
* sky-gpuif.c (gif_io_read_buffer, gif_io_write_buffer): Correct
assertion polarity.
(gif_read_tag): Disable faulty DMA-tag testing code.
the SCEI PKE simulator's output on its own test sample (tsv432.in).
* sky-pke.h (PKE_MEM_READ, PKE_MEM_WRITE, PKE_REG_MASK_SET): Add
trace file records.
* sky-pke.c: (pke_track_write): Removed function. Replaced with
in-line modifications to VU tracking tables.
(pke_attach): Attach VU tracking tables. Use line buffering on
trace files.
(pke_issue): Spit out additional trace records.
(pke_pc_operand_bits): Correct bitfield masking error.
(*): Replace sim_read/write with kludge PKE_MEM_READ/WRITE
throughout.
(pke_code_unpack): Correct numerous small bugs in operand decoding
etc.
