[Gambas-user] JIT on archlinux fails to build

[Emil Lenngren]

Try revision 4774, it should solve that bug.

You can use the environmental variable GB_JIT=info to make LLVM dump out
the optimized code. To debug how the code looks like before optimization
passes, you have to uncomment a line //M->dump() in
gb.jit/src/jit_codegen.cpp.

Enumerating classes is apparently not that good implemented yet..
