Hi,all I tried to run the generated whole-program bitcode of BIND,but I got some information: 0 lli 0x0000000000feda16 1 lli 0x0000000000fed88f 2 libpthread.so.0 0x0000003df340eee0 3 libc.so.6 0x0000003df28332f5 gsignal + 53 4 libc.so.6 0x0000003df2834b20 abort + 384 5 libc.so.6 0x0000003df282c2fa __assert_fail + 234 6 lli

Sorry i really forgot to mention one thing. I downloaded the X86 binaries of llvm+clang and llvm-gcc from llvm download site. i hope that is not a debug build.

Hi all, LLVM is built without debug enabled. Also i am not forcing lli to use interpreter mode. so i dont think the reason is not because of debug build or interpreter mode. *step 1: * compiled the 3 files (generic_replica.c ,xacc.c and dacc.c) with clang-cc to llvm bytecode files using -emit-llvm-bc and (-O0/-O3) options *step 2:* bytecode obtained from step 1 (generic_replica.bc, xacc.bc and

He is probably using the interpreter on a debug build. Evan On Nov 14, 2009, at 1:40 PM, Eric Christopher <echristo at apple.com> wrote: >> >> for -O3 results refer attachment. >> time clang (- >> O0) llvm-gcc(-O0) >> gcc(-O0) >> real >> 0m10.247s

Hi Eric, Here's the C code (example.c): include <stdio.h> int main() { printf("testing\n"); } Here's the LLVM IR (from llvm-gcc): ModuleID = 'example.c' target datalayout = "e-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-v64:64:64-v128:128:128-a0:0:64-s0:64:64-f80:128:128-n8:16:32:64" target triple =

Hi Alberto, Can you please file a bug for it, with the test case attached (if you haven't already). Thanks, Ehud.

Hi all, I have attached the complete test suite. it has different directories for gcc, llvm-gcc , clang and lli-clang. Source code , makefile and run script (contains number of times the program should execute) for each case are available inside each directory. * FOLLOWING ARE THE STATISTICS WHILE USING LLI FOR SINGLE ITERATION*

Hi Nick: The first problem have been solved by calling llvm-ld: $ llvm-ld -o hellosin.llvm hellosin.bc -lm $ lli -force-interpreter=true -load=/usr/lib/libm.so hellosin.llvm.bc hello sin: 0.50 The pthread problem remains after llvm-ld: $ lli -force-interpreter=true -load=/lib/libpthread.so.0 phello.llvm.bc 0 lli 0x08796bf8 Segmentation fault For those who are getting "invalid

Hi Nick: Thanks for the response. You are right about sinf. I changed the constant to sscanf(argv[1], ...), and it gave me back 0 again. I also compared the disassembled code, and saw it was indeed the case. The primary reason I use interpreter is because I wish to do runtime checking on memory access pattern in multithreaded C programs. for example, if thread one is in the critical section, I

Milind, Have you filed a bug on this? If not, can you please open a bug report (http://llvm.org/bugs)? -Hal ----- Original Message ----- > I am hitting an LLVM assertion from the llc tool iff the bitcode file > is optimized at -O3 level by opt). -O1 and -O2 levels of opt do not > cause this assert. > > LLVM version 3.4svn > DEBUG build with assertions. > Built Jul 14

Alberto: The usual recommendation in these circumstances is to use a JIT class instead of the interpreter. You're using -force-interpreter though, so I assume you really want to use the interpreter for your use case?

As of LLVM 3.2, is it possible to use iostream with the MCJIT or interpreter execution engines? I'm getting some errors... Each of these commands correctly prints "hello": echo -e '#include <stdio.h>\nint main(){ printf("hello"); }' | clang -cc1 -emit-llvm-bc -x c++ | lli -use-mcjit echo -e '#include <iostream>\nint main(){ std::cout <<

I am hitting an LLVM assertion from the llc tool iff the bitcode file is optimized at -O3 level by opt). -O1 and -O2 levels of opt do not cause this assert. LLVM version 3.4svn DEBUG build with assertions. Built Jul 14 2013 (15:39:08). Default target: x86_64-unknown-linux-gnu Host CPU: amdfam10 I have attached the input bc file before -O3 optimization :bzip2.del.bc.tgz I have attached

Hi David, Thanks for the suggestions. I can definitely provide the example bc file and image ( please see the attachments ). For the debug + asserts I need a bit of more time. Anyway the full output of lli is: lli --force-interpreter examples/pngpixel_crash.bc 0 0 examples/mini.png png_ptr->width: 1 max_pixel_depth: 24 row_bytes: 28 Unknown constant pointer type!

The entire program became 'print constant string'. There is certainly a bug

Hi, I don't see the LLVM bug I filed (http://llvm.org/bugs/show_bug.cgi?id=16780) making any progress. Can someone suggest me whether the bug is in the correct state? -Milind On Fri, Aug 2, 2013 at 1:29 PM, Milind Chabbi <Milind.Chabbi at rice.edu> wrote: > Hi Hal, > > I have filed http://llvm.org/bugs/show_bug.cgi?id=16780 > > -Milind > > On Fri, Aug 2, 2013 at
