The module is shipped with the source code, so it's from the developers (not me). The path in the source tree is: llvm-3.4.2.src/lib/Transforms/Hello After compiled LLVM *#./configure --prefix=XXX --with-binutils-include=/path-to-binutils-2.24/include --enable-debug-symbols --enable-debug-runtime --enable-assertions --disable-optimized; make; make install* LLVMHello.so is generated at

I just follow the tutorial: http://llvm.org/docs/WritingAnLLVMPass.html Actually it's not only my module, I used the LLVMHello.so (a sample module in the source tree) and get the crash (I didn't do anything :-P). ~t On Tue, Aug 12, 2014 at 12:57 AM, Eric Christopher <echristo at gmail.com> wrote: > Weird, it definitely shouldn't be crashing.

no... I guess verifier runs by default and it points to the doFinailization() function :-( ~t On Tue, Aug 12, 2014 at 12:53 AM, Eric Christopher <echristo at gmail.com> wrote: > No idea, I was suggesting to just run the verifier to see if it would > pinpoint what's broken about the module. > > -eric > > On Tue, Aug 12, 2014 at 12:52 AM, Tianyin Xu <tixu at

Oh, you mean opt -disable-verify? Yes, it does eliminate the crashing... Do you know what's the problem, Eric?

Hi all, I find all my passes are all broken with LLVM 3.4. Then I tried out the LLVMHello.so specified in the LLVM doc, http://llvm.org/docs/WritingAnLLVMPass.html and it also crashes. It seems all the functions in the pass do work, but LLVM crashes in the doFinalization() step. Does anyone know this problem? Thanks! Tianyin

Hi, Rafael, Thanks a lot for the explanation! Could you explain a bit more (sorry I'm not from a compiler background)? So, what's the difference in the analysis perspective? What does "reading ELF files and archives" and "creating a list of symbols passed to llvm's internalize pass" do? I checked a little bit the corresponding .ll file generated according to the

Hi, I'm sorry if the question doesn't fit this mailing list. It seems that LLVM does not have a user support mailing list so I post it here. We're using the LLVM tool chain as our static analysis infrastructure. So, basically we use LLVM to generate an aggregated .bc file and analyze the .bc file. The question I want to ask is what's the difference between using the LLVM gold

Hi Justin, I believe the PTX section in the link below need some love, updating "lib/Target/PTX" to "lib/Target/NVPTX" for example. Would you like to take a look? http://llvm.org/docs/CodeGenerator.html#the-ptx-backend Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia Sinica, Taiwan (R.O.C.)

Hi all, I think it's Gentoo's bug, but I want to know if anyone has the same issue here. I am compiling LLVM trunk on Gentoo (gcc 4.5.2), and I get error message below, --- make[4]: Entering directory `/nfs_home/chenwj/llvm-3.1/svn/build/tools/clang/lib/Frontend' llvm[4]: Compiling InitHeaderSearch.cpp for Release+Asserts build

Hi Pawel, PTX already be replaced with NVPTX. However, PTX subdirectory still sit in lib/Target in 3.2 release. Do you think update the release tarball is a good idea? Also could you remove it from the trunk? Thanks. Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia Sinica, Taiwan (R.O.C.)

How about sending a patch which remove those obsolete code, and let others give comment? Cheers, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab,

Hi all, While building/testing LLVM/Clang on ARM, I often have problems that are undocumented on the website. I would like to contribute my experience if possible so that others can benefit from it.

Hi there, I compiled clang+gold using a gcc under path /s/gcc-4.3.1/bin/. Later on I do configure and make for flex-2.5.35, and the following command is invoked: "/path/to/my/gold/ld" --hash-style=gnu --no-add-needed --eh-frame-hdr -m elf_i386 -dynamic-linker /lib/ld-linux.so.2 -o flex /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../crt1.o

Hello all, I caught a problem related to pthread library. I built llvm and llvm-gcc then compiling a multithreaded benchmark written in POSIX thread library. The command "llvm-gcc -o bench bench.c -lpthread" ran well while "llvm-gcc -c bench; llvm-ld -o bench bench.o -lpthread" crashed. It told that "llvm-ld: error: Cannot find library 'pthread'". I could
