[Aldor-l] Compiler development

[Pippijn van Steenhoven]

Hello Aldor developers,

tonight, I have restarted my work on the compiler (I had no time for it
anymore and now I have forgot most of the things I knew back then). I
would like to verify the quality of the compiler by splitting it up into
subsystems and perform extensive regression tests on each. By splitting
them up, I also want to understand and possibly document the internal
working of these subsystems.

The problem I am currently having is that the memory allocation subsystem
crashes in various ways. The most annoying crash happens when I try to
make it output debug information using the STO_DEBUG_DISPLAY macro and
the GC_DETAIL environment variable. It causes a segmentation fault in
vfprintf where something tries to access memory at address 0xc0. This is
clearly caused by undefined behaviour elsewhere.

Is anybody actually still developing Aldor or does anybody have a clue
about the compiler internals? I'll have uploaded the code I have here to
svn://svn.xinutec.org/aldor/trunk. It does not include the changes I made
before tonight. It does not include the make scripts either, since they
are not license-compatible with the APLv2. (Would it be possible to use
SVN external repositories and just let svn fetch the required files
without those being license-compatible?)

Regarding license issues, I no longer care about it. If the Aldor
Software Organisation wants the "royalty-free" "unrestricted" right to
modify and redistribute my changes, that would only be good, since it
would mean there are actually people out there besides me who care about
the quality of the compiler.
