sash to run.
1) fixed fetchdecode64.cc to fix the operand size at 64 bits in long mode for moves
to/from CRx
2) minor patches to sse2.cc to fix unimplemented and 64 bit variants of sse2
instructions.
Because source files were added/removed it would require an update
of the windows and macos project files, so I want to wait until after 2.0.
M Makefile.in 1.51 back to 1.50
M cpu.h 1.121 back to 1.120
M fetchdecode.cc 1.37 back to 1.36
M fetchdecode64.cc 1.33 back to 1.32
M sse.cc 1.17 back to 1.16
A sse2.cc 1.27 back to 1.26 (added back)
R sse_move.cc removed
R sse_pfp.cc removed
- to bring these changes back again, all we have to do is
"cvs update -j tmp-before1 -j tmp-after1"
sse.cc -> general SSE stuff and SSE integer (MMX extensions)
sse_move.cc -> memory transfer and shuffle opcodes
sse_pfp.cc -> packed floating point operations

debugger, SMP, and x86-64. A few macros were missing the CPU_ID argument,
and a few passed nonexistent variables to the instrumentation macros.
- I changed CPU_ID into a plain old macro instead of an inline call to a
trivial which_cpu() function, and removed which_cpu().

In bx_cpu_c::reset method I set bx_cpu->async_event to 2
so execution in the cpu_loop gets stopped early.
Previously, async_event was set to 0, and with repeatable
instructions, after reset, eip was incremented by the instruction
length, so execution would resume at 0xffffX (X being >0, the current
instruction length).
In halt state I check now for reset with async_event is 2, so
reset works also when the cpu is halted. (update to Peter change)
I hope I fixed this the right way, please report any strange behaviour.
For a whole lot of configure options, I put #if...#endif around code that
is specific to the option, even in files which are normally only compiled
when the option is on. This allows me to create a MS Visual C++ 6.0
workspace that supports many of these options. The workspace will basically
compile every file all the time, but the code for disabled options will
be commented out by the #if...#endif.
This may one day lead to simplification of the Makefiles and configure
scripts, but for the moment I'm leaving Makefiles and configure scripts
alone.
Affected options:
BX_SUPPORT_APIC (cpu/apic.cc)
BX_SUPPORT_X86_64 (cpu/*64.cc)
BX_DEBUGGER (debug/*)
BX_DISASM (disasm/*)
BX_WITH_nameofgui (gui/*)
BX_SUPPORT_CDROM (iodev/cdrom.cc)
BX_NE2K_SUPPORT (iodev/eth*.cc, iodev/ne2k.cc)
