similar to: [LLVMdev] problems with llvmgcc

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

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

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

Since we only have a Solaris version of the front-end (llvmgcc), we need to compile .c -> .ll files on a solaris machines in order to run the tests in Programs/. Doing this manually for all the C source files is really difficult. I added a flag called RUN_GCC_ONLY in test/Programs/Makefile.programs that will cause gmake to run only llvmgcc. Run the following in test/Programs to build .ll

As I have been threatening: (http://mail.cs.uiuc.edu/pipermail/llvmdev/2002-October/000141.html) to do (http://mail.cs.uiuc.edu/pipermail/llvmdev/2002-September/000092.html) for some time now, I have regenerated the X86 and Sparc C frontends. They are now in-sync again and both emit the 'external' keyword instead of 'uninitialized' as appropriate (plus other changes). If you are

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

Hi all LLVMor, I just tried to compile a simple code and analyze the number of the basic blocks. But after compile, what I got, the bytecode is seems to be optimized bytecode. So the information of basic blocks is not what I expected. I want ot use the code as example to see how some of code optimization methods work. However, after compiling file using llvm test.c -o test, bytecode file

Thanks very much for taking the lead on this, Reid. I think this will prove to be a valuable thing and, as you

LLVMers, If you're not working from the CVS "head", you can ignore this. Otherwise, please read it! I have committed changes to CVS head that require changes to your build environment. This is part of PR432. The changes involve getting the CFE to build an executable named llvm-gcc instead of gcc. The hyphenated name was chosen to be consistent with other LLVM tools, it is also

Its basic I'm not sure that I agree with this. Compilers need to be extremely predictable and

Great, thanks, it solved it!

Here are a few bits of news about the C frontend: 1. I have ported it to compile and run under linux. On our research machines, it is available here: /home/vadve/lattner/cvs/gcc_install_x86 Note that this C compiler will still generate "64-bit" LLVM files, thus the code will probably not work right if run through the C backend, then compiled on x86. For middle-end

Ok, email the lists is preferred though, because then there is an archive, and others with similar questions can get them answered that way. I'm CC'ing the list because some of the info in my response may be useful to others.

Hello! I have compiled LLVM without errors and try to do a simple hello world test using the llvmgcc frontend, llvmgcc -o hello hello.c and I get this error message: gcc: installation problem, cannot exec `gccas': No such file or directory What have I one wrong/what needs to be done?

If that still doesn't work,

Finally lli and llvmgcc can work under my directory. I wrote the following simple program and compiled it using gcc and then run it without any problem. But when I tried to compile it using llvmgcc and lli, llvmgcc gave me the following error message which I cannot understand: xli3|csil-suna37|~/cs426|[181]% llvmgcc test.c -o test test.c: In function `init': test.c:10: warning: cast to

Hi, I'm a newbie and just installed LLVM on a Linux box. I followe "The LLVM Getting Started Guide" on the web and have some trouble on the section "An Example Using the LLVM Tool Chain". When I compile the simple hello.c program with "llvmgcc hello.c -o hello", the system complains -- gcc: installation problem, cannot exec `gccas': Permission denied. Does
