similar to: [LLVMdev] Running llvmgcc only (under test/Programs)

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. Thanks, xiaodong xli3|csil-suna48|~/cs426|[13]% llvmgcc scalarize.c -o scalarize xli3|csil-suna48|~/cs426|[14]% scalarize Cannot load value of

The problem with llvmgcc invoking as instead of llvm-as has been fixed. 3 llvm-specific executables needed to be copied into a default location where gcc can find them if it does not find them as configured (gcc was configured for the paths on our research machines and copied over). Let us know if you have additional problems. --Vikram > -----Original Message----- > From: llvmdev-admin

For some reason, it is trying to use the 'as' in your path, which is the LLVM

Rahul, Were you talking about tracing in the sense of "profiling" (which Anand did), or tracing of values as they are computed for debugging generated code (which I did)? For tracing of values for debugging, the answer is yes: we insert code in each BB and print out the values computed in that BB that are live at the end of the BB (so we don't print out temporaries computed and

I just had a chance to read some of follow-up comments on Reid's initial document. I agree with Chris's discussion below of what is needed for users to get IPO/lifelong opt'n via LLVM without extensive changes to Makefiles, and about what .o files should contain. This is in perfect agreement with what I just said about how users should view LLVM. --Vikram

Sorry for that last message, it was intended for llvm at cs instead of llvmdev at cs. --Vikram http://www.cs.uiuc.edu/~vadve > -----Original Message----- > From: Vikram S.

Great! Could you please add a /localhome directory to each of them? Since there are 2 disks per machine, perhaps the best thing to do would to make /localhome a real directory and make separate local directories on each disk, so that we can each do something like this: /localhome/vadve -> /mounts/seraph/disks/0/localhome/vadve /localhome/lattner ->

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,

Dear llvm, I just tried to compile a simple file hello.c. But each time I used llvmgcc hello.c, it gave me the following error: xli3|csil-suna33|~/cs426|[13]% llvmgcc hello.c as: error opening '/var/tmp//ccapglpE.o': file exists! Use -f command line argument to force output I really got confused. Could you please let me know what's wrong? thanks, Jerry

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

Our department outreach coordinator spotted this and forwarded it to me. It's a lot of speculation but I thought many of you would be interested. --Vikram http://www.cs.uiuc.edu/~vadve http://llvm.org Begin forwarded message: > From: "Jennifer C La Montagne" <jsandone at uiuc.edu> > Date: June 8, 2007 12:53:00 PM CDT > To: "Vikram Sadanand Adve"

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

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
