In terms of the run time library, I think everything should work except the g-table and g-dyntab units which also use virtual addressing. ^ permalink raw reply [flat|nested] 3+ messages in thread

But at least on OpenBSD i386, I haven't been able to get most java runtime tests to run: boehm-gc doesn't work with dynamic libraries for us. I don't know why, and I haven't had time to find out. boehm-gc needs very specific support for each processor, each OS. I've read through parts of it, it's really not simple code, a real maze of a mess of #ifdef. the current gc used by gcc is, comparatively, very easy to work with. And it works on most everything, as there are degraded versions of it that demand very little where the OS suppport is concerned. ^ permalink raw reply [flat|nested] 3+ messages in thread
