ab59a34604 bandit: Modify address ranges. 
- Increase I/O space from 22 bits (4 MB) to 23 bits (8 MB).
- Add Special Cycles and Interrupt Acknowledge Cycles at 14 MB offset.
- Pass Through range at 16 MB offset is 16 MB size. VGA and 24 bit physical addresses can go here.
- Bandit is 32 MB except for pci1 which has GrandCentral at Bandit's 16 MB offset.

4479387580 Remove using namespace std from remaining header files 
It's somewhat of an anti-pattern, and can lead to conflicts with
other symbols (e.g. the Windows build failure in https://github.com/dingusdev/dingusppc/actions/runs/11762906342/job/32766290288,
I removed `using namespace std` from timermanager.h to fix that one).

Merge pull request #127 from mihaip/upstream-opcode-dispatcher 
ppc: Use a unified opcode lookup table
 2024-11-30 12:51:08 -07:00
Mihai Parparita
b759f25d87 ppc: Use a unified opcode lookup table 
Instead of a primary opcode lookup table with 64 entries and a few
smaller tables with 4-2048 entries, use a single 64 * 2048 (128K)
entry table to dispatch opcodes.

Helps with performance, since we avoid the function call overhead for
some frequently-used instructions (e.g. branch, integer, floating point).
Saves ~2 seconds from the time to Welcome to Macintosh (same measurement
methodology as #125)

Secondarily also makes opcode registration/decoding a bit more uniform,
and scannable, since it's now all in initialize_ppc_opcode_table.

564c43c907 Remove ppc_cur_instruction global variable 
Replace it wth an explicit opcode parameter that is passed around. That
is both slightly easier to reason about (to trace where it comes from)
and slightly faster, since it can be read from a register.

On my machine takes booting to "Welcome to Macintosh" being output in
a verbose boot of Mac OS X 10.2.8 from 31.8s to 30.6s (average of 5
runs, measured using deterministic mode and looking at when execution
reaches PC 0x90004a88).

2d90aff408 ppc: Remove unncesessary function declarations 
ppc_opcode16 and other functions are only needed in the implementation in
ppcexec.cpp, they don't need to be in the header.

fp_return_double and fp_return_uint64 have no uses (as of 2141a72b87)
can can thus be removed altogether.

Similarly ppc_fpu_off has no uses (as of bb3f4e596e)
and can be removed.
