1998-02-20* PKE sim unit testing continuing. The DIRECT and MPG instructionsFrank Ch. Eigler1-28/+53
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.

1998-02-20* Continuing unit testing of PKE simulator. It now successfully matchesFrank Ch. Eigler2-155/+210
