Respected Sir/Madam, As I was developing some part of compiler for a project. I require grammar (BNF or EBNF) for converting the C code in the IR as it is not been mentioned any where over your official website. Awaiting for your help. Regards, Vijay Daultani. M.Tech student IIT Delhi

I don't know what you mean by "converting the C code in the IR". Regardless, LLVM does not have BNF or EBNF forms (or any formalized grammar) for C, nor for LLVM IR. Sorry!...

I am curious how do you guys do it anyways?

...iable Also, using lli to interpret the following example program [3] produces the status code 42. global i32 42 define i32 @main() { %foo = load i32, i32* @0 ret i32 %foo } As neither the LLVM Language Reference Manual, nor the comments of the LLVM IR reference implementation, include a full EBNF of the language grammar, one has to make educated guesses and cross-reference information from LangRef.html, comments in LLParser.cpp and the code in LLParser.cpp. I'd love to see an EBNF grammar for LLVM IR at some point in the future, as this would open up for very interesting possibilit...

Hello everyone, While developing a parser for LLVM IR, I seem to have stumbled upon a potential ambiguity in the LLVM IR assembly language grammar. Most likely there is something which I may have overlooked, so wanted to reach out to a more experienced crowed for some feedback. How would the following set of tokens be interpreted [1]? declare void @foo() unnamed_addr global i32 42 As far as

...e formal language specifications for LLVM IR. A lot of these are in the language reference manual online, but it's difficult to dig some of the things out of that document. For instance I was wondering what are all the tokens for the language. Some of the CFG grammar definitions are there in EBNF, but some of them are not and only examples are given. Are these documents online anywhere? Thank you, Tim -------------- next part -------------- An HTML attachment was scrubbed...

...own educated guess is that for an LLVM expert, NAC backend development will require something between 6 to 12 weeks. Thus the proposed contract is for a 2 or 3 month duration. However, this can also be negotiated. We can also supply you with additional helper materials and tools such as: - EBNF NAC grammar. - NAC yacc/bison grammar. - NAC lex/flex scanner. - NAC grammar for the Gold Parsing System. - TXL grammar for NAC. - Numerous examples of C code translated to NAC using our prototype C frontend. - Numerous examples of handwritten NAC programs. - A NAC-to-C backend tool to help you w...

Does anyone have a good working e-mail validator? or even some regexp to make the validates_format_of work right... that would be awesome. Also, maybe an online tutorial for regexp. i''ve always been afraid of it but i think it''s time to face the fears. thanks! -- Posted via http://www.ruby-forum.com/.

As I go along in my project and explore these features I might be willing to produce code for additional chapters but I don't think I have time to dedicate to it now. What was the problem?
