PADDSIW, PSUBSIW, PMULHRW (named PMULHRWC in the code as recognized by some assemblers), PMULHRIW, PDISTIB, PMACHRIW, PAVEB, PMAGW, PMVZB, PMVNZB, PMVLZB, PMVGEZB, FTSTP, FRINT2, FRINEAR, FRICHOP are implemented for Cyrix 6x86MX. Cyrix 6x86(L) only has the last 4 instructions.
1. vga_on global variable removed, as it didn't play well with 2 subsystems at once (8514/A and XGA both enabled).
2. Emulate the Foreground/Background Color aliases of PIX_TRANS properly when not executing a command.
3. Voodoo 3D override now works properly (again) with Mach32 PCI cards and others by turning the 8514/A timer off and on accordingly.
* separate (ibm8514|xga)_enabled into (ibm8514|xga)_standalone_enabled
and (ibm8514|xga)_active, the former being enabled only for standalone
8514/A or XGA cards, the latter for all 8514/A and XGA-capable cards
and not saved into the config file;
* remove (ibm8514|xga)_has_vga and replace all uses of it with
(ibm8514|xga)_standalone_enabled;
* Qt UI: the checkboxes for standalone 8514/A and XGA are now correctly
grayed out if an (S)VGA card with 8514/A or XGA capability is selected,
including cases when the card is an internal/onboard one; said cards are
now no longer appear as SVGA multi-monitor compatible.
Cursor and mapping on Windows 2.x' 286/808x XGA driver.
Pattern and DMA bus master fixes to OS/2 2.x/Warp's XGA driver.
Software reset no longer causes glitches to the screen using XGA (x86.c)
- Added SL-Enhanced versions of Intel 486 CPUs and Enhanced AMD Am486DX2/DX4 CPUs
- Cleaned up the 486 CPU types and updated intel_4x0.c to reflect this
- Fixed some incorrect EDX reset and CPUID values
- Blacklisted non-SMM capable 486 CPUs on the Soyo 4SA2 motherboard
- Merged the non-OverDrive and OverDrive Intel DX4s because of further research confirming them to be functionally identical
- Removed SMM support on early 486 CPUs
