[LLVMdev] LLVM parsers for popular languages? - Python, Rust, Go

[mats petersson]

Typically, the AST is language-specific [as concepts in one language often
doesn't exist at all in another language, e.g. Python List and Dictionaries
don't exist in C], so outputting it as "another language" is not always
easy (or even possible without much infrastructure in the target language).

I also have absolutely no idea what you mean by "Summary" - I expect you
mean the essential parts of the code, minus error checking and such, but I
have a hard time understanding how you differentiate between the
algorithm's essential parts, and "unnecessary error checks" [unless your
code understands the algorithm, but then you could just as well write a
program that outputs various algorithms in different languages, which would
be easier than taking in source in one language and output it in another
language].
