digitalmars.D.announce - LDC 1.43.0

Glad to announce LDC 1.43. Some major changes:

* Based on D 2.113.0.
* Support for LLVM 22. The prebuilt packages use v22.1.8.
* Minimum LLVM version raised to 18.
* DRuntime and Phobos now support WASI preview levels 1 and 2, as 
well as Emscripten, incl. general WebAssembly fixes for EH and GC 
support. Thanks to Demetrius for making this happen!
* New prebuilt addon packages for simple cross-compilation, for 
Windows, Android, WASI and Emscripten targets.
* The ` restrict` UDA is now supported for dynamic-array 
parameters too. Builtin array ops use it, enabling 
auto-vectorization.
* Revamped codegen for *naked* DMD-style inline assembly, lifting 
a few former restrictions.
* dcompute: Support embedding native device code (PTX and SPIR-V) 
into the host executable's `.rodata` section.

Thanks to all contributors & sponsors!

Very nice job with this release, and it seems like a big one! I 
tested my emscripten demos with the new release and everything 
seems to be working on my end. I will look forward to trying out 
the Android addon packages later on this term. Thank you to 
everyone for your hard work!

Thanks. I missed this announcement. I tried cross-compiling for 
Windows, and it's obviously way easier than setting up a Windows 
environment, especially for those of us that don't use Windows.

In case anyone else gets confused when setting it up, the 
installation directory and the addon both have /etc 
subdirectories. You need to merge them.

 Wow!


I am just a fan boy at this point about this, but it works really 
well.
Here are some posts I made where I'm using Phobos with 
`wasm32-wasip1` on the web:
- https://x.com/Kapendev/status/2101410708315394168
- https://x.com/Kapendev/status/2101690051557998751

Only thing I am not sure is how to avoid that WASI Libc error the 
compiler prints if you try to compile without `-c`. Right now I 
am linking manually like this:

```sh
ldc2 -c --mtriple=wasm32-wasip1 source/index.d source/wasip1libc.d
wasm-ld \
     -o index.wasm \
     index.o wasip1libc.o \
     "$LDC_WASIP1_FOLDER/libphobos2-ldc.a" 
"$LDC_WASIP1_FOLDER/libdruntime-ldc.a" \
     --export=_start --gc-sections --error-limit=0
```

Update. We got it to build with this now :)
```sh


ldc2 --mtriple=wasm32-wasip1 -c source/wasip1libc.d
ldc2 --mtriple=wasm32-wasip1 -link-internally source/index.d 
wasip1libc.o

Any intention to make an addon for amd64-linux-glibc2.17? I heard 
many complaints that people can't easily compile backward 
compatible executables.

No. That should primarily be a question of having and using an 
according ancient C toolchain (`-gcc=…`) for linking; prebuilt 
static druntime and Phobos from the regular `linux-x86_64` 
package might just work (just unsure about their C parts). And 
there's the Alpine packages too, to build fully static musl-based 
binaries (`-static`) - either on Alpine directly or with a musl 
toolchain -, or cross-compile to glibc-Linux on an ancient distro 
(since the `ldc2` executable is e.g. fully static).

Another option is to use opend's zig-based helper, described here:
