similar to: [LLVMdev] LLVM LL(k) grammar

Hello; I was planning to add a new instruction to the LLVM IR (and later to MIPS backend) for TLS(Thread level speculation) support. For this I tried to follow the steps described in http://llvm.org/docs/ExtendingLLVM dot html#instruction. But I could not find any llvm/lib/AsmParser/Lexer.l and llvm/lib/AsmParser/llvmAsmParser.y file in both the svn repository and the source code downloaded

Try removing

For VC++, I solved this by having bison/flex put the files into the obj directories. I also have it unconditionally regenerate the files if bison/flex is available, and copy them from src if they are not. Chris Lattner wrote: > On Wed, 11 Jan 2006, Vladimir A.

No solutions come to mind. Conflicts are conflicts and must be resolved manually. This situation should only occur if you change the .l/.y file and then update the .h/.cpp files after someone else has changed the .l/.y file and regenerated the .h and .cpp. That doesn't seem like a high frequency scenario that we need to worry about. Not sure there's much we could do even if it was. Reid.

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) ...

The syntax in the IR reference doesn't make it optional: @<GlobalVarName> = [Linkage] [Visibility] [DLLStorageClass] [ThreadLocal] ... Cheers. Tim.

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

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

Checking in ParserInternals.h would probably be a good thing about now... because if you take this update, it doesn't compile. -scooter On Thu, Jan 1, 2009 at 11:12 PM, Chris Lattner <clattner at apple.com> wrote: > I just checked in a new parser for .ll files, deleting the old bison > parser.

I just checked in a new parser for .ll files, deleting the old bison parser. This means that the last of the ".cvs" files are gone from the tree, which will hopefully make the world a happier place for windows users in particular. I tested it thoroughly but expect minor fallout, if you notice any problems, please let me know.

I have a new instruction that takes 2 labels, and in SelectionDAGISel, I have it doing "CurMBB->addSuccessor()" for both machine blocks. The DAG node it creates also takes both blocks as SDOperands. When I lower to x86, the not-fallthrough block disappears. If I run llc with --fast, the blocks stay around, so it must be an optimization pass of some sort that doesn't realize my

I recently subscribed and saw in the archive that Eric Astor was asking for a formal grammar (unlikely the first time for such request.) Currently there are a few problems in making such a thing so I was curious if Mr. Gruber has made any thoughts about moving toward one? This would also allow a more ?clean? parser which would get rid of some of the current problems (bad nesting[^1],

Hello all, I am trying to add a new type; however, I found the information in the web site out of date. The modification was: 2008-12-11 12:23:24 -0600. I am interested in the below files: 1. llvm/lib/AsmReader/Lexer.l: add ability to parse in the type from text assembly 2. llvm/lib/AsmReader/llvmAsmParser.y: add a token for that type I could not find them. Could someone tell me what
