History: when the emulator was first developed on OSX 10.4 (PowerPC),
the inline keyword was added by profiling with Apple's pretty
fantastic Shark profiler. Apple's version of gcc had an -fobey-inline
switch that the makefile used to force gcc to obey the inline keyword.
This macro does the same thing
37.5 Prime MIPS on Linode VM to 42.5 MIPS. gvp-> was faster on the
PowerPC architecture when gvp was kept in a dedicated register, but
that does not apply to Intel.
Old:
Timing CPU, 20.0 ticks per second...
35.3 Prime MIPS for 16-bit ADD loop
40.0 Prime MIPS for 16-bit MPY loop
42.1 Prime MIPS for 16-bit DIV loop
21.4 Prime MIPS for 32-bit ADD loop
30.8 Prime MIPS for 32-bit MPY loop
28.6 Prime MIPS for 32-bit DIV loop
57.1 Prime MIPS for 16-bit X=0 loop
44.4 Prime MIPS for 32-bit X=0 loop
37.5 average Prime MIPS

- Remove long integers so x86_64, where long is 8 bytes, is like i686
compile, where long is 4 bytes.
- Dont' handle xon/xoff on sys console in full duplex
- Add geom hash for DEMO emulator
- Add -mmacosx-version-min=10.4 option for DEMO emulator
- Add 1-line AMLC and 2-node PNC to DEMO emulator
problem with remote terminal sessions:
1. netlink to remote Prime
2. a prirun
3. l (list directory)
4. displays a little, then a longish pause up to 30 seconds, then the rest
Does a similar thing with stat us. Hitting Enter will cause it to
finish, while typing characters does not. I suspect this is a problem
with Prime's networking code, but not sure.
Also, if async I/O is used, the QUIT. OK, message doesn't appear after
ctrl-p. I think they are getting wiped out by Primenet's buffer
flushes.
All of this might be subtle timing problems because I changed the
default clock rate from 250/330/500/whatever times per sec to 20 times
per second in this rev 19 version of Primos.
