Only three days after the 0.8 version, I finished the 0.8.1 version.
It’s a minor version, so there is no big changes to the language. However, I added support for the do while loop in the source code.
Another change is that assignment is now returning a value. That allows you to make some code like this one:
int a = b = 5; b = (a = 4) + 1;
This new version includes also some new changes for the optimization engine. I implemented constant propagation and copy propagation for offset assignment. For example:
a(8) = 4; b = a(8);
becomes:
a(8) = 4; b = 4;
And the last change is that the concatenations that are detected to be constant after some optimization are made at compile-time by the optimization engine. This simplify a lot the generated code for source file with a lot of concatenations.
The next version (the 0.9) will introduce floating point operations and parameter passing with registers (probably only in 64 bit). It’s also possible that I will try to implement a first version of global optimization.

You can find the compiler sources on the Github repository: https://github.com/wichtounet/eddic
The exact version I refer to is the v0.8.1 available in the github tags or directly as the release branch.
