I am the maintainer of clisp, a package that has had portability a problem on sparc. I have found a solution to the problem, but it involves disabling the allocation of various globals to registers. clisp uses the registers g4-g7 to store such things as it's stack pointer. These registers are obviously being clobbered somewhere. Are there any other registers available that could be used? I suspect not... Or can anyone point me to documentation on when these registers need to be saved?
Thanks,
