Improvement LDC support

Upstream issues

kassane commented 6 months ago

Based on some information, it is expected to improve support for nogc and/or betterC. Currently the user_data example requires GC because of AA (associative array)

kassane commented 5 months ago

Improvement wasm support

The latest changes are intended to remove support for custom-Druntime (obsolete and incomplete). Only wasm32-target as betterC will be allowed. #20 This needs to be re-tested and improved.

However, for a higher priority, it is still necessary to resolve the linking conflicts of the objects generated by ldmd2/ldc2

Note: ldmd2 is just the wrapper for the ldc2 compiler, using the dmd flags (ldc2 -ldmd - w/ dmd library).

Building wasm-target involves what steps?

Four steps (current)

libsokol build
Build an object with ldc2 (not an executable or library). [wasm32-unknown-unknwon-wasm is wasm32-freestanding]
- wasm-unknown-emscripten get Warning: unknown target OS: emscripten
Capture the previously built object and use zig to re-address the object references. [wasm32-emscripten]
Get the object to emcc. It will generate the final binary (*.wasm). [wasm32-unknown-emscripten]

Build tests

In the following, I have tested it manually (no zig build system).

ldc + emcc - same steps [both enable LTO]

No trouble! Enjoy your travels.

Note 2: LTO between ldc2 and emcc cause warnings. Prefer enable LTO in ldc2 only (no or minimum warnings)!!

After fix ldc2 (master) issue (add wasm32-unknown-emscripten)... I have discovered a strange situation, in that when enabling LTO on all in release mode.

warning: Linking two modules of different target triples: '/home/kassane/sokol-d/zig-cache/o/11f2f18f48ea24e538f790ad4c0e12f8/libsokol.a(sokol_gfx.o at 101382)' is 'wasm32-unknown-emscripten-musl' whereas 'ld-temp.o' is 'wasm32-unknown-emscripten'

wasm32-unknown-emscripten-musl ?? Maybe based on wasi target. The issue is fixed (without warnings) when passing -Dtarget=wasm32-emscripten-none.

kassane commented 5 months ago

After new updates and the possible inclusion of imgui support. As you can see, build.zig is quite long and complicated.

Unlike the sokol-zig approach (by @floooh), sokol-d has everything included, which requires extending the support in build.zig. So far, the port of pacman.c/pacman.zig to pacman.d is in progress, as a first external solution using sokol-d.

Any suggestions for other approaches to reduce such complexity?

Maybe pacman.d can serve as a reference.

kassane commented 3 months ago

After some testing with zig-master regarding external package management, I will need to postpone porting the build system modularization.
- https://ziggit.dev/t/how-to-get-fullpath-on-build-zig-from-v0-14-0-dev/5469
Also, it requires looking into the issues with shaded examples in wasm32, while knowing ldc2's poor support for the target.
Also evaluate the possibility of updating imgui support (replacing cimgui to dear-bindings).
Another alternative to try is to add nuklear support.

kassane commented 2 months ago

The next ldc2 version brings improved wasm32-emscripten-musl support.

Emscripten: The compiler now mimicks a musl Linux platform wrt. extra predefined versions.

More info: https://forum.dlang.org/post/xmrqpocmcfwpajxvzfal@forum.dlang.org

Remember: Currently, the wasm32 target in this project has LTO enabled (ldc2/zig cc/emcc) in release mode.

However, wasm32-emscripten and wasm32-wasi in Zig links musl-libc by default. Causing conflict on the part of the object generated by ldc2 and sokol library. Add -none in wasm triple-target to bypass linker error.

This compiler improvement, it might help linking with musl-libc on LTO enabled. In debug mode (LTO off) emit warnings yet!
