> clang+llvm package takes 300-400 MB, that's almost an order of magnitude difference

I ship a statically compiled llvm + clang with my software and it does not add 300-400 mb to the binary at all, only something like 20-30 mb.

If you’re willing to compile, ship and support custom builds of .NET runtime, gonna be less than 20-30 MB.

coreclr.dll (the runtime) is 4.9 MB, clrjit.dll (JIT compiler) is 1.3 MB. The rest is mostly standard libraries, the largest piece of that is System.Private.CoreLib.dll at 9 MB. The numbers are for Win64 version of .NET 5.0.2.

Another thing, for .NET apps the runtime is required anyway, the overhead for runtime code generation is zero.

For C++ apps, llvm + clang (or an equivalent) is only needed on developer’s computers, not something you’d normally ship.

unless you want to JIT-compile C++ code at runtime which is the original point.
