I'm talking about Go's linker. In the Go runtime, the G and M
pointers need to be in a per-process storage area. On Plan 9,
this is the stack. Right now, the offset of the pointers is
hard-coded in the linker to be just before the Tos structure.
The problem is that the value that was chosen is not correct
when running on 9vx because the top of the stack is is at
0x10000000 instead of 0xdffff000 (as it is on native Plan 9).
I think that the Go 8l should not hard-code this value but,
instead, discover it somehow ... though I'm not sure how.
Anthony
