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

I am curious how do you guys do it anyways?

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

Seems that Vijay is asking about converting C program to LLVM IR On Mon, Jul 29, 2013 at 9:26 PM, Eli Bendersky <eliben at google.com> wrote: > > > > On Sat, Jul 27, 2013 at 9:02 AM, Vijay Daultani <vijay.daultani at gmail.com>wrote: > >> Respected Sir/Madam, >> >> As I was developing some part of compiler for a project.

Reed, Are you working on a grammar of the LLVM syntax or also on a full semantics? Steve Zdancewic's group at U. Penn. is working on a formal operational semantics for LLVM. It is partially complete and Greg Morrisett at Harvard is planning to build further on it.

Hello Tim, Thank you for getting back to me. The language grammar as defined by the LLVM Language Reference Manual [1] does not include the details of the LLVM IR parser reference implementation. The following extract from "lib/AsmParser/LLParser.cpp" illustrates that unnamed globals are allowed [2]. > /// ParseUnnamedGlobal: > /// OptionalVisibility (ALIAS | IFUNC) ...

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

This might be a very beginner question, but I'm looking for an example for something that I have never done. Suppose that I wanted to express actions with respect to lifted semantics of CPU instructions to an intermediate representation, BAP IL or LLVM IR. How might I go about providing a Backus Naur Form specification and then dynamically interpreting those lifted instructions by also

Hi I am Yogesh M.Tech Student for my final year project i am trying to write a ANTLR grammar and generating CFG for same for more please help me or give any pointer                 Thanking you !                                                                                                               Regard

The LLVM IR language documentation is not, and isn't intended to be, a true language standard document in the same way that the C or C++ standards are. For any given case, check the docs first, and if your question isn't answered there, check the source

Has anyone seen any attempts to give Markdown a PEG (parsing expressions grammar) recognizable by some ruby PEG parser generator grammar like Treetop? http://treetop.rubyforge.org/

A long time ago, when I devised the grammar and structure of the Microsoft C++ name mangling scheme (decorated names), the document describing the object model and the name decoration scheme were made publically available. Perhaps this is still available publically, or perhaps Microsoft might be willing to share an up to date definition of the name-decoration grammar, especially in light of the

Hello Surinder, The existing hand-written parser is callable from almost anywhere so the only reason you'd need to have a parser for it would be to extend it. Originally it was written using Flex and Bison but Chris Lattner rewrote it from scratch to catch more errors at the parsing stage. The only feature I've found to be missing from the existing LLVM-AS utility was an include

Has anyone written a grammar for LLVM for ANTLR. I mean an ANTLR grammar that parses LLVM instructions. Is an LLVM grammar available for any other parsing tool? Surinder

Hi Sam, Thanks for your reply. I am implementing my research (http://www.it.usyd.edu.au/~suri/Detecting%20Buffer%20Over.pdf), a translation of LLVM to a simple non-deterministic language to detect buffer overflows. It involves (1) printing a control flow graph of basic blocks of a function (easily done) (2) translating each llvm statement to a corresponding data flow language (needs ASTs to
