I tried a simple hack on 9vx.
First, I had sysbrk_ return the max possible value instead of the
requested value. I.e., if go runtime asked for 768MB, I had it return
something less than TSTKTOP, which is around 256 MB. I like this
because if we change the USTKTOP on 9vx in future we don't have to
recompile the go runtime, and a single binary can run on many 9vx
systems which might have different limits compiled in.
Unfortunately the runtime code ignores the returned value from sbrk_;
strike one.
I then had it return -1 when asked for more memory than could be
returned; Got this:
term% ./testgo.out
throw:
and that was it.
Russ, could the go runtime maybe use the value returned by sbrk
instead of assuming it got all it asked for?
