similar to: [LLVMdev] I try to compile to LLVM code

Hello Borneq, If you want to compile bitcode into assembly, you need to invoke the llvm-as and llc commands on it to convert it from LLVM Assembly source to bitcode and then native assembly source instead of llvm-gcc. If that doesn't work, post back here, --Sam ----- Original Message ---- > From: Borneq <borneq at wp.pl> > To: llvmdev at cs.uiuc.edu > Sent: Wed, August

How link it with stdio - I use printf llc is virtual machine? If I call llc with hello.s.bc it do

I've been tossing around some ideas about high-level backends. Say, have LLVM emit Perl code. Sounds whacky but isn't. It's good for the first bootstrapping phase in environments where you don't have a C compiler, where you don't have a cross-compiled binary for download, but you can execute Perl. It also makes a great inspect-the-sources-with-an-editor stage for aspiring

Anyone, can you say what was the reason to rename bytecode?

Hmm.. I didn't explain the problem completely last time. I am creating a drop-in replacement for gcc and gfortran that runs an additional pass on the bitcode before generating the native binary. Here's whats happening: If the source code compilation process builds a static library (.a archive file), I need a means to link the `.a' file statically into the application. So if the

Thats correct. But using llc becomes a problem when I have archives (.a files). I could, in theory, extract its contents to a tempdir and then use llc and link but just wondering if there is a more elegant solution. Ashay On Mon, Sep 12, 2011 at 3:00 PM, Dmitry N.

Sorry, at what step do you need archive? llc emits binary, it does not perform any linking, thus it does not need anything except the input bytecode file. Then during linking you can link whatever archives of binaries you want. 2011/9/13 Ashay Rane <ashay.rane at tacc.utexas.edu>: > Thats correct.

Hi list, As long as I know English the word "bit" is a "small pice", . Why in set of documentation ir is "bytecode", in other set or llvm source is "bitecode"? What is the right? Different people call the same thing such differently. -- best regards Ariel -------------- next part -------------- An HTML attachment was scrubbed... URL:

I see. And what's the purpose for outputting bitcode into *.o and *.a files? Do you want to perform an LLVM pass on linking step? 2011/9/13 Ashay Rane <ashay.rane at tacc.utexas.edu>: > Hmm..

No, I am running the LLVM pass at the compilation step. So by the time I reach the link step, the transformed bitcode has been generated. Ashay On Mon, Sep 12, 2011 at 4:12 PM, Dmitry N.

Teja, Your mention of .s being bytecode confuses me, but if you're asking how to lower a bitcode (.bc) or IR file (.ll) to assembly (.s) than llc is the tool you are looking for. llc -O2 path/to/bitcode/input.bc -o output.s -Chris On Mar 7, 2013, at 10:39 PM, teja tamboli wrote: > Hello, > > I am looking for tool to convert file from either (.s) bytecode or (.bc) bitcode to

Hi, I want to compile apache httpd using LLVM compiler. However, I am interested in generating llvm bytecode files [.s or .ll] files along with its executables. I followed steps mentioned in link : http://stackoverflow.com/questions/13851661/compiling-apache-httpd-into-llvm-bytecode-using-clang However after following all instructions when I compile httpd with following options I get directly

Hello, I am looking for tool to convert file from either (.s) bytecode or (.bc) bitcode to .asm file. Basically assembly instruction file for my x86 backend. I think so we can use llvm-objdump. However I am not able to figure out its exact options. Could you please tell me how to do that? -- Thanks, Teja -------------- next part -------------- An HTML attachment was scrubbed... URL:

Ashay, If I understand correctly, in hw.o you would have llvm bytecode, while linker expects regular object binary. Probably first you need to emit asm out of bytecode using llc? - D. 2011/9/12 Ashay Rane <ashay.rane at tacc.utexas.edu>: > Hello, > Sorry for the late reply.

Hi all, I am working on my Master's project in security and for this I need to do following things : 1. I have a IR bytecode of the main program. I want to insert dead code from other source files (e.g. cygwin files or the Linux files) in main program's IR byte code. 2. In order to insert code, I can try following two ways : (i) I have observed that these IR bytecode files are just

Here is the bulk of the sanitizing. My residual doubts center around the question whether we still do/want to support (un)compressed *byte*code in 2.0/2.1. I need a definitive word on this to proceed. My understanding is that bytecode is already gone, but there are still some functions/enums that really deal with *byte*code (instead of *bit*code). I did not touch those areas, so the attached

Hello, I'm considering LLVM for a project, and I wanted to take a look at its bytecode representation/instruction set. So I decided to try to compile the /bin/ls command as bytecode (no particular reason to use ls) and look at it. So I got GNU coreutils from http://ftp.gnu.org/gnu/coreutils/coreutils-5.0.tar.gz, built it to make sure it works, then replaced gcc, ld, ar and ranlib with

I tried to install the SAFECode in LLVM 2.6 following the instruction in Install.html. But when I do the step: # cd projects/poolalloc # make I get the errore below: llvm[2]: Compiling qsort.c for Release build (bytecode) llvm[2]: Compiling strdup.c for Release build (bytecode) llvm[2]: Compiling qsort.c for Release build llvm[2]: Compiling strdup.c for Release build llvm[2]: Compiling qsort.ll
