Devang, I read Chris's notes so I got all this information there already.

Right now I am writing passes just to look for arrays & structs I am trying to identify the array by parsing the memory description(use regex's) ex./ { [20 x i8], i32 } *- for a struct. is a structure with a character array of size 20 and an integer. I'm not sure if llvm provides an easier way to do this? The type id for most arrays comes out to be a pointer rather than an array, its

Dear All, Here's a question Vikram and I received. Is the LLVM JIT thread safe? -- John T. -------------- next part -------------- An embedded message was scrubbed...

Does llvmgcc4 convert the high-level AST to LLVM (like llvmgcc3x) or does it go from GIMPL to LLVM? If the latter, would it be possible to allow some TreeSSA optimizations before emitting LLVM? --Vikram http://www.cs.uiuc.edu/~vadve http://llvm.cs.uiuc.edu/ On Jul 31, 2006, at 1:10 PM, Devang Patel wrote: > llvmgcc4 emits LLVM byte code before executing GCC optimizations, > so one

Our department outreach coordinator spotted this and forwarded it to me.

That sounds like a problem. Just so I understand, do you mean there isn't the run-time support etc. to write back ends for the C++ language, or that the compiler IR is also somehow insufficient to write a code generator? --Vikram Associate Professor, Computer Science University of Illinois at Urbana-Champaign http://llvm.org/~vadve On Jul 11, 2009, at 3:00 PM, Granville Barnett

I too am disappointed that not all talk slides are posted. To me it speaks poorly of the whole meeting since there were parallel sessions and not everyone could attend in person all the sessions they wanted to. The slides are, I thought, meant to be like the "proceedings" and If I recall some of the Apple slides are present from previous years but not this year. Vinod On Sat, Oct 17,

When you create a parser via ANTLR you specify the output language of the resulting recursive descent parser, at the moment there exists no C++ output template to my knowledge, thus you would have to generate the parser as C code for which a template exists. The runtime support should be there, at least partially but it won't use things like exceptions, nor will it have a very modular design

Dear Prof. Adve, Now I can use llvmgcc to compile a .c file into .bc file. But I still have trouble simply run the .bc code. Below is the sequence I got when I tried. I really don't know what's going on here. Please let me know how can I fix it.

Dear LLVM users, The development of LLVM has been supported primarily by funding from the National Science Foundation and the University of Illinois. in order to maintain our sources of funding and attract new ones, It is important for us to be able to document how LLVM is benefiting companies, universities, other organizations, and individuals in the outside world.

The gcc front-end page in llvm.cs.uiuc.edu seems to be down for the last 18 hrs. I was finding that tool very useful to get the syntactic constructs, could someone fix it ?

How do you define a data structure for this purpose? Do you mean individual data types like structs or arrays? Or higher-level "logical" structures like lists, trees, or hash tables? The former is obviously easier but even the latter is possible, in some cases. --Vikram Associate Professor, Computer Science University of Illinois at Urbana-Champaign http://llvm.org/~vadve On

So isn’t it a good example that shows that your intrinsic *cannot* be opaque and that IR passes need to be modified to handle not only the IR-region
