6582536591 Inline ppc_set_cur_instruction 
It's used in the main emulator loop (ppc_exec_inner), and the function
call overhead adds up.

By inlining it, time to boot to the Finder using a 7.1.2 install CD
and a 6100 ROM goes from ~6700ms to ~6400ms (with clang 14 on a
M2 Max)

Merge pull request #67 from mihaip/upstream-power 
Fix emulation of doz, dozi, and nabs POWER instructions
 2023-12-01 07:48:38 -07:00
Mihai Parparita
1b4de3b64e Fix emulation of doz, dozi, and nabs POWER instructions 
doz and dozi were storing the result into the wrong register.

nabs was not taking into account two's complement storage of numbers
and was just setting the signed bit.

These two instructions are used in the implementation of text
measurement in native QuickDraw on 7.1.2/the PDM ROM, and the incorrect
values were resulting in nothing being rendered. With the fix text
appears when booting from the 7.1.2 CD.

Merge pull request #66 from mihaip/upstream-pending-events 
Fix keyboard events occasionally being dropped
 2023-11-24 19:17:51 +01:00

d08b486db0 Fix keyboard events occasionally being dropped 
AdbKeyboard would copy the event into its own fields and set the
changed field, so that we could return the event when register was 0.
However, if a subsequent event was received before ADB polling, the
previous event would be overwritten and lost.

Fix this by maintaining a queue of events, so that we can return
everything since the last poll.

Fix "a" key always being as as a keyup
 2023-11-24 11:35:18 +01:00

d45bba924d Fix "a" key always being as as a keyup 
We were using an empty value on the second byte of the ADB keyboard
register 0, but that maps to the "a" key. This manifested itself
as the Key Caps DA never showing the "a" key as being down.

Switch to a non-existent key for the second byte.
