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.
Some of them are "generic" in hotspot (eg in the else of a !windows
check or a !zero check). Didn't check JDK side.

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

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,
