You can try ldc and llvm intrinsics

Ah, yep!
pragma(LDC_alloca) void* alloca(size_t);
This appears to work with ldc. It would be nice if there was a
way to do this with dmd/other compilers as well though. If it
were up to me I'd have alloca defined by the language standard
and every compiler would have to provide an implementation
like this. At the very least I'd like to have an alloca that
works with dmd, as I want to do debug builds with dmd and
release builds with ldc.
embedded platform?
An embedded platform would be a good use-case for this, but I'm
just trying to do this on Linux x86_64 personally. It's a fun
experiment to see how far I can push D to give me low-level
control without dependencies
