I was half suggesting that, half wondering. I suspect that most of the
queries on the value
of that flag are inside some "if <platform>" test so we may only need
to make the OS X
build path understand the combined setting for those cases, minimising
the disruption.

Would it be feasible to overload ARCH_DATA_MODEL to take a string like "32+64", "32/64",
or "Universal" (even though that's an ambiguous misnomer)?

'ARCH_DATA_MODEL' has historically been used to select a build as 32 or 64 bit.
So 'ARCH_DATA_MODEL=32' ought to be able to select a 32 bit only build without
too many build changes. Making that support 32+64 as well may be appropriate
for OS X builds.

Awesome, thanks much James.
Is there a pre-existing flag or naming convention for architecture-related
build flags? Obviously we want to align with existing precedent, and get the
HotSpot and JDK sides to use the same flag. :-)

Yes. I can file a bug and look into this, Mike.

One caveat...
For the JVM, we've preserved 32/64-bit universal builds. Currently, the
JVM universal build only includes 64-bit support. Additionally including
32-bit requires 3 Makefile uncomments. However, there may likely be
additional work on the JDK side to fully support the same.
That's good to know, but that should really be keyed off of a build flag (which
can default to 64-bit only). Should we file a CR through the Oracle bug
reporter to get the process started to change this for HotSpot?
Is there someone who can help restore the 32/64-bit build-ability for the JDK
side, or at least direct us as to where we can start filing a CR?
Curious,
