Interesting approach!
Are there any numbers available regarding compilation speed and execution speed?

MultiOberon is an Oberon Compiler with 3 different backends:

BlackBox Native x86 code Generator (now 1.6)
Ofront Generated C-Language Code Translator;
LLVM representation Generator.

The current version is 0.8 for BlackBox 1.6. BlackBox 1.7 and linux support is planned in 0.9.

Optimization usage is in development, the figures below are preliminary.
Compile time (no optimization) - 270% LLVM, 100% BlackBox;
Loading time - 1330% LLVM (JIT compiler), 100% BlackBox;
Execution time (no optimization) - similar.

The optimizer is not available now, llc.exe with -O0..-O3 can be used instead.

Does it support generating OCF modules with correct descriptors and meta information?

MultiOberon has 3 backends:
- Omb (based on DevCPP) generates OCF modules as usual;
- Omf (based on OFront) provides descriptors and meta, but does not support dynamic modules loading (to be implemented next);
- Oml (LLVM based) provides descriptors and meta, and dynamic loading is implemented in 2 ways:
--- LLVM bytecode .bc module file;
--- COFF and ELF .o module file.
