Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Compiling History: A brief tour of C compilers
> QBE is a new optimizing backend much simpler than LLVM; cproc and cparser are two of the C compilers that target it, in addition to its own minic.
I thought cparser targeted libFirm. That's what their GitHub page says [0].
"It acts as a frontend to the libFirm intermediate representation library."
> We really need a production quality open source C compiler that is actually written in C.
I honestly think cproc or cparser are almost there already. For cproc, you just need to improve the quality of code optimization; it's really QBE you'd need to change. For example, you could change unnecessary multiplications by powers of 2 into left shifts, improve instruction selection so that subtraction is always something like "sub rax, rdi" and not "neg rdi / add rax, rdi" [1]).
For cparser, I notice slightly higher quality codegen; libFirm just needs more architecture support (e.g. AMD64 support appears to work for me, but it's labeled as experimental).
