4a6a3aff5d em: add macro to force gcc to obey inline keyword 
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

9054d69446 em.c, etc: use gv.xxx instead of gvp->xxx for 13% speed increase, from 
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

New:

Timing CPU,  20.0 ticks per second...
  42.9 Prime MIPS for 16-bit ADD loop
  53.3 Prime MIPS for 16-bit MPY loop
  47.1 Prime MIPS for 16-bit DIV loop
  24.0 Prime MIPS for 32-bit ADD loop
  38.1 Prime MIPS for 32-bit MPY loop
  32.0 Prime MIPS for 32-bit DIV loop
  57.1 Prime MIPS for 16-bit X=0 loop

35adf0905a devpnc.h: moved xmit setup code from OTA to pncxmit; 
move loopback handling to pncxmit1 so it is used for broadcasts;
added reason to disconnects for better logging;
change some traces to prints for better logging;
my node is always authenticated

cd351506ea devpnc.h: drive connections from PNC xmit requests rather than 
ring.cfg, for faster start times of large rings
 2020-02-27 20:00:58 -05:00
Jim
120079666f devpnc.h: expand listen backlog for big rings, use TCP_DEFER_ACCEPT so 
Linux holds onto connections until the uid is sent.  Otherwise, the
delay between making a connection and sending the uid will be larger
than MAXACCCEPTTIME, causing large rings to fail
 2020-02-27 11:53:07 -05:00
Jim
bf3c1a3df2 devpnc: after accept, make fd non-blocking to avoid deadlock when multiple emulators make connect requests, then accept(), then block reading uid that never comes. 2020-02-26 21:39:21 -05:00

ebd8a8a3fa secure: muck up RP instead of keys if secure() is bypassed, because 
bad keys give an emulator error about a bad generic, while a bad RP
('7777/0) is a failure mechanism already in secure()
