Yes, that is correct (I figured this out the hard way).
What would really help me, and wouldn't have much design impact on
gcj, is if there were a switch to create one __GLOBAL_foo per class,
not one per compilation unit. It would be even cooler if this
__GLOBAL_foo was named deterministically (right now the name seems to
be the mangling of a randomly chosen method). Since there would be a
1:1 mapping from classes to GLOBALs, the name could just be
Is this an easy change or a hard one? Would anybody be kind enough to
point me at the right part of gcc and give me a few hints? I feel
pretty comfortable screwing with libgcj, but I've never tried to
modify gcc before.
