Subject: Link standalone programs at 0x80010000.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6478085c7b04fe15435e520d0ed8888a650c643b;p=riscv-isa-sim.git

Link standalone programs at 0x80010000.

This leaves some memory for pk, where it keeps tohost/fromhost which we
cannot just write to.
