I think Fogus was able to summarize it quite well in his "Six works of Computer Science-Fiction" blog post [0]: "Wirth’s magnum opus is the quintessential example of Computer Science alternative-history world-building."

You are right, but as you can see at page 11 (Figure 4 rightmost AST) of The Oberon System Family paper [0], Wirth's approach was extended to "hint" destinations as well. [0] https://www.research-collection.ethz.ch

It would be great to have a simple Virgil x86-64 backend based only on the destination-driven code generation technique, and compare the performance of the generated code (and compilation speed) with the official optimizing x86-64 backend.

It is interesting to see that this approach has been used by Niklaus Wirth in most of his compilers, see "Compiler Construction - The Art of Niklaus Wirth" by Hanspeter Mössenböck [0]. This technique was also described by David R

The Oberon programming language is 37 years old. Since it is a memory safe language a compiler for the JVM can be written (with some workarounds), for example see the self-hosting compiler oberonc [0]. [0] https://github.com&#x2F

When I benchmarked oberonc [0], an oberon-07 self-hosting compiler for the JVM, it took about 100 ms with a hot VM on a old Intel i5 @ 2.80GHz. That compiler follows the same one-pass compilation approach. [0] https://github.com&

I wrote a self-hosted one pass compiler exactly to showcase Niklaus Wirth's approach to writing compilers: https://github.com/lboasso/oberonc We often forget this alternative way (with its pros and cons).

by lboasso 7y ago
Here is the repo: https://github.com/lboasso/oberon0 Yes, you can write small Oberon-0 programs and compile them with an Oberon-07 compiler, but it is simpler to just use the Oberon-0 compiler from the repo above.

If you are interested in the Oberon-07 language, I made a port of Wirth's compiler for the JVM, see [0]. Several other implementations exist for different platforms [1]. [0] https://github.com/lboasso/oberonc [1]

Another excellent resource is "A Philosophy of Software Design" [0], from John Ousterhout (known for Tcl/Tk, Raft, RAMCloud, Log-Structured File System). Like Niklaus Wirth, he is striving for designs that fight complexities

Go was heavily influenced by Oberon, in fact Robert Griesemer is a former Wirth's PhD.

I have been following the development of Oberon-07 (and submitted minor fixes to Prof. Wirth) over the years. The compiler's source code is the fruit of refinements and simplifications accumulated over 30+ years (more if you include hi

Wirth's compilers generated reasonably good code: 80% of the performance of optimizing compilers with 20% of the effort. The first Java client jit compiler, was developed by Robert Griesemer (former PhD student of Wirth). The design of
