Description

What steps will reproduce the problem?

  1. Compile svn revision 4756 on OSX 10.6 using instructions from wiki to
    get dev environment set up (see comment from celgil near the bottom),
    modifying SConstruct according to mailiam's comment on Nov 10 and the
    command scons osx=64cocoa nowx=true
  2. Create configuration in ~/Library/Application
    Support/Dolphin/User/Config/ (my config is attached)
  3. Run DolphinNoGUI with a game iso.

What is the expected output? What do you see instead?
The game should run, but instead it crashes. Output:

What version of the product are you using? On what operating system?
revision 4756

Please provide any additional information below.
Turning the JIT option "UseDynarec" off prevents a crash, but of course, it
runs very slowly.

For completeness, I'll note that I was testing against New Super Mario Brothers Wii,
and I have verified that Dolphin in windows (also revision 4756) can load and run the
iso properly (dual boot system) with comparable settings.

Oh, and OS X builds a crash report to send to Apple. The contents of which are attached
here. Not sure how much it helps.

Not sure what dev handles osx issues.

jit crash but jittest works fine

  • Category set to jit

  • Relates to performance set to Yes
  • Operating system OS X added

This is due to the LoadStore parts of the cores, now applicable to both JIT and
JITIL. Currently these parts of the core are disabled, but games that rely on them
heavily (Ikaruga) will run VERY slowly. Only way to fix them is to make sure the code
generated by the cores are 16bit aligned, which is a requirement that OSX has.

Right, I haven't updated this in a while. A while ago, it was found it wasn't
destroying the 16bit alignment at all. This error is due to MAP_32BIT not available
in OSX, so all of the casts from 64bit pointers to 32bit pointers fail because we are
using regular 64bit addressing. I've tried working on the core with a little bit of
success, but not much. This is over my head, I can't work on it.

Obviously started this. Only thing I'm currently failing to fix is Optimize
Quantizers, and I'm failing at that just because I'm a horrible programmer.
