7e41d08620 Fixed problem with shift imm instructions 2002-12-30 08:03:34 +00:00
Stanislav Shwartsman
e1d5cddc6d Fixed a problem with zero-count shift in following instructions: 
PSRAW_PqQq    (MMX)
PSRAD_PqQq    (MMX)
PSRAW_PqIb    (MMX)
PSRAD_PqIb    (MMX)

PSRAW_VdqWdq  (SSE)
PSRAD_VdqWdq  (SSE)
PSRAW_PdqIb   (SSE)
PSRAD_PdqIb   (SSE)

When register was shifted by 0 bits the result produced was incorrect.

Now Bochs fully passes MMX test provided by
Hentai Yagi [hentai_yagi@yahoo.com.au] !

1cd38bb7dd Recommitted SSE code reorganization. 
Fix in FXSAVE/FXRESTOR opcodes -> If the OSFXSR bitCR4 is not set, the FXRSTOR instruction does not restore the states of the XMM and MXCSR registers.

9b2914fd1d - Temporarily revert Stanislav's changes between 2002-12-18 and 2002-12-19. 
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"
