2f6a740b65 works on Linux x64
still needs to be fixed for everything else

090627b3c1 Remove the last ConfigEntry state (#1902)
* Get rid of `ConfigEntry::ExternalBIOSEnable`

- Now the BIOS files themselves are checked
- The frontend's `Config::ExternalBIOSEnable` is not affected

* Add `JITArgs`

* Pass the JIT status to the `ARM` constructors

* Encapsulate `NDS::EnableJIT`

* Pass `JITArgs` to `ARMJIT`'s constructor

* Remove the `JIT_*` `ConfigEntry`s in favor of members

- Allow all the JIT args to be set with `NDS::SetJITArgs`
- Encapsulate the JIT-related parameters in `ARMJIT` so they can reset the block cache if changed
- Update the active (or newly-created) console in the frontend with adjusted JIT args

* Make audio bit depth and interpolation configurable in `NDSArgs`

- Define enums for both
- Give those settings default values in `NDSArgs`
- Remove `ConfigEntry::AudioBitDepth`
- Initialize these settings in the relevant SPU constructors

* Move the last DSi-specific logic in `Reset` to its own subclass

* Remove `ConfigEntry::DSi_FullBIOSBoot`

- Add members to `DSi` instead for getting and setting this
- Update the frontend to accommodate these changes

* Oops, missed a spot

* Remove `ConfigEntry::Firm_MAC` and `Platform::GetConfigArray`

- Also move the MAC parsing code to `ROMManager`

* Remove the last `ConfigEntry` state

- Make GDB support configurable via members

* Add some `#ifdef`s that I'd almost forgotten

e973236203 Refactor NDS and DSi to be objects (#1893)
* First crack at refactoring NDS and DSi into objects

- Remove all global/`static` variables in `NDS` and related classes
- Rely more on virtual dispatch when we need to pick methods at runtime
- Pass `NDS&` or `DSi&` to its constituent components where necessary
- Introduce some headers or move some definitions to break `#include` cycles

* Refactor the frontend to accommodate the core's changes

* Move up `SchedList`'s declaration

- Move it to before the components are initialized so the `map`s inside are initialized
- Fields in C++ are initialized in the order they're declared

* Fix a crash when allocating memory

* Fix JIT-free builds

* Fix GDB-free builds

* Fix Linux builds

- Explicitly qualify some member types in NDS, since they share the same name as their classes

* Remove an unnecessary template argument

- This was causing the build to fail on macOS

* Fix ARM and Android builds

* Rename `Constants.h` to `MemConstants.h`

* Add `NDS::IsRunning()`

* Use an `#include` guard instead of `#pragma once`

346dd4006e Move all core types into namespaces (#1886)
* Reorganize namespaces

- Most types are now moved into the `melonDS` namespace
- Only good chance to do this for a while, since a big refactor is next

* Fix the build
2023-11-25 18:32:09 +01:00
544fefa27f Refactor the JIT to be object-oriented (#1879)
* Move TinyVector to a new file

- So it's less sensitive to #include ordering

* Forgot to include assert.h

* Refactor ARMJIT_Memory into an object

* Oops, forgot a declaration

* Refactor ARMJIT to be contained in an object

* Remove an unused function declaration

* Add a missing #include

* Remove a now-unused global

* Use ARMJIT_Memory's own memory access functions

* Fix some omissions in the ARM JIT

* Move libandroid to be a member of ARMJIT_Memory instead of a global

* Default-initialize most fields in ARMJIT_Compiler.h

* Define NOOP_IF_NO_JIT

* Finish refactoring the JIT to be object-oriented

79dfb8dc8f Introduce Platform::Log (#1640)
* Add Platform::Log and Platform::LogLevel

* Replace most printf calls with Platform::Log calls

* Move a brace down

* Move some log entries to one Log call

- Some implementations of Log may assume a full line

* Log the MAC address as LogLevel::Info

78839f862e JIT fixes
- fix fastmem problems on linux
- small fix memory leak
- SlowWrite functions always take in a 32-bit variable so that the C compiler knows that the values aren't necessary zero extended
- a few other stylistic things
- handle SIGBUS as well (for macos)

0d845c9e69 Random minor fixes (#757)
* Fix incorrect/questionable assert() usage

Originally reported by https://lgtm.com/projects/g/Arisotura/melonDS/?mode=tree&ruleFocus=2159000700,
but also includes a bunch of other fixes.

* Fix some `printf` warnings

Rule https://lgtm.com/projects/g/Arisotura/melonDS/?mode=tree&ruleFocus=2160310550

* Remove useless check

It is never passed thanks to `if (num_in < 1) {...; return}` before
Rule https://lgtm.com/projects/g/Arisotura/melonDS/?mode=tree&ruleFocus=2154840804

* Add missing header guard, rename other to avoid conflicts

Rule https://lgtm.com/projects/g/Arisotura/melonDS/?mode=tree&ruleFocus=2163210746

* Make DSi_SDDevice destructor virtual

Rule https://lgtm.com/projects/g/Arisotura/melonDS/?mode=tree&ruleFocus=2158670642

* Use thread-safe localtime_r, assign `time` result directly

Rule https://lgtm.com/projects/g/Arisotura/melonDS/?mode=tree&ruleFocus=2154840805

* Fix MinGW build

It needs _POSIX_THREAD_SAFE_FUNCTIONS to export `localtime_r`

3001d9492c abandon pipelining on jit
fixes Golden Sun Dawn
this makes the cpu state incompatible between interpreter and JIT. That's why switching cpu mode requires a restart(not requiring is stupid anyway) and the pipeline is manually filled when making a save state.
