Changes: 23 Jun 2004: (Early in the morning.) Performing a general code cleanup (comments, fixing stuff that led to compiler warnings, ...). Disabling MIPS16 support by default, and making it a configure time option to enable it (--mips16). This gives a few percent speed increase overall. Increasing performance by assuming that instruction loads (reading from memory) will be at the same page as the last load. First by assuming that a vaddr -> paddr translation for instruction loads almost always is preserved (gaining a few percent speed), and then that a paddr -> host memblock translation also holds if the instruction is in normal RAM (which led to some more percents of speed increase). :-) This is definitely a fine night for coding... For example, the total time from starting the emulator until Ultrix 4. 2 shows it graphical login dialog is 48 seconds! 22 Jun 2004: (Late.) Trying to track down the last SCSI tape bugs. Removing all dynamic binary translation code (bintrans), starting from scratch again. 22 Jun 2004: (Early in the morning.) Finally! After many many hours of trial and error, I got the SCSI tape stuff to work; when going past the end of a file, automagically switch to the beginning of the next. 21 Jun 2004: Removing the Nintendo 64 emulation mode, as it is too uninteresting to support. Adding SCSI tape device support (read-only, so far, and not 100% working). Fixing a bug which caused the cursor to be corrupted if new data was written to the framebuffer, but the cursor wasn't moved. 20 Jun 2004: Adding a program which converts SGI prom dumps from text capture to binary, and some hacks to try to make such an IP22 PROM to work better in the emulator.
