Overall the only important question is what hosts will do on 64Bit.
Do any
of you any other 64Bit compatible AU host other than AULab?
None that I know of.
I almost totally migrated my CarbonViewBased AU to using a Cocoa UI
but have
no other app to test with and just found out that GarageBand 09
doesn't
include a 64Bit version.
You're right it doesn't. I'm pretty sure they will come out with a
64bit version when Snow Leopard is ready...
I was about to ask about 64 bit hosts, for entirely different
reasons! Because my additive synth is very register heavy in its
inner loops, I see a significant performance improvement in the x86_64
version over the i386 version. (Like, 20 - 30%). Currently I'm happy
running it under the minimal host I wrote that lets me to run the
synth standalone, but I'd like to know if there are any "real" 64 bit
hosts out there.
By the way, I don't know if anyone else has noticed it, but Mac OS
seems to occasionally get itself into a state where it prefers to run
the 32 bit code rather than the 64 bit code. During debugging I
thought I was going mad, so I modified the code and now the 64 bit
version of my code displays a special indicator in my UI. For
testing, I also found it helpful to use /usr/bin/lipo to split out 32-
bit-only and 64-bit-only executables from AULab, just to remove any
last traces of doubt about what I was running.....
