What am I misunderstanding about the SPARC v8plus mode?

You also need to look at stuff conditionalized on TARGET_V9.


Apple's PowerPC patch holds function-local 64-bit values in GPRs
and allows all 64-bit arithmetic and logical operations to be performed.
The functionality is broader, so it requires internal changes to the
common parts of GCC.

I don't believe you.




David is correct on the first account. Apple patch keeps 64bit values in GPRs. If this can be accomplished without
changes to common part please let us know how sparc port accomplishes this.
