6e254743c1 Added missing sanity check. 
The sanity check would help to detect real Bochs crash issue under Win x64 with MSDEV
configure script under Mingw env decided that SIZEOF_INT_P == 4 which is terribly wrong for 64-bit host.

6252632e31 Fixed segmentation fault that could happen under rare conditions with handlers chaining speedups enabled. 
I saw that issue under gcc 4.9.0. for some reason gcc 4.9.0 didn't optimize next handler call in all fpu opcode handlers.
As result, instead of finishing the handler and jumping to next one, the next handler is called blowing up stack.
After some long period stack overflow might occur.

The fix simply limit the max chaining depth to 1000 traces (should be enough)
The same fix should be able to address the stack overflow problem when compiling with -O0 and handlers chaining speedup enabled.

f8267ec3a7 rework in CPUID code (fixed code duplication). Re-enable perfmon reporting in CPUID because Win8/Win10 installation doesn't want to start without perfmon reported. TODO: implement basic perfmon support (at least only fixed counters) because win7-64 doesn't install with perfmon reported but not implemented 2014-10-15 08:04:38 +00:00

8d1e3b2ac1 Added statistics collection infrastructure in Bochs and 
implemented important CPU statistics which were used for Bochs CPU model performance analysis.
old statistics code from paging.cc and cpu.cc is replaced with new infrastructure.

In order to enale statitics collection in Bochs CPU:

- Enable statistics @ compilation time in cpu/cpustats.h
- Dump statistics periodically by adding -dumpstats N into Bochs command line
