Bugpoint is a standalone too and does not require any separate script. The script is a helper for using ssh as a remote client. Bugpoint should not be aware of any details how the test program will be delivered to a remote target, get executed there, and

I've made quite a bit of progress getting bugpoint to work with our (non-gcc) tools. In fact I caught the alignment bug I recently posted about using it. But it's not there yet. In particular, I am seeing this scenario a lot (comments in brackets): *** Found miscompiling pass: -instcombine Emitted bitcode to 'bugpoint-passinput.bc' [ Good! This is progress! ] *** You can

I'm having some trouble using bugpoint with newer version of gcc (bugpoint debug output below). I looked into the "conflicting type for malloc" problem and it doesn't seem easy to solve due to the unknown size of size_t (see LowerAllocations.cpp). The "void main()" problem is probably a result of this test being converted from Fortran. I'll have to dig into

Attached is a patch that fixes it for the cmake build.

Hi, I am trying to reduce what I believe to be a miscompilation bug. Running lli on my bitcode file causes a segmentation fault. However, running bugpoint as bugpoint file.bc gives me the following errors, /tmp/ccAdmNqH.o: In function `_ZL17bus_error_handleriP7siginfoPv': bugpoint-test-program.bc-Vega5s.cbe.c:(.text+0x1b4e1): undefined reference to `std::cerr' /tmp/ccAdmNqH.o: In

Sorry to ask about a documented use of bugpoint, but I am having trouble understanding what to do. I would like to be able to use bugpoint to simplify test cases, when the symptom is a run time difference in the testprogram behavior. That looks like what is described in the documentation as "miscompilation or perhaps code generation problems". There are examples in the LLVM doc showing

While running the llvm tests, I get several error messages like these: [1/1] Running the LLVM regression tests FAILED: cd /home/steve/llvm-build/test && /usr/local/bin/python /home/steve/llvm/utils/lit/lit.py --param build_config=. --param build_mode=Release -sv --param llvm_site_config=/home/steve/llvm-build/test/lit.site.cfg --param

Hi, I have a program that runs when statically compiled using llc and gcc but crashes with a segmentation fault when run with lli. I am trying to debug it with bugpoint and the initial part of bugpoint seems to be suggesting that I am somehow missing the linking with the libraries having dlsym/dlopen although I am passing it to lli : *$ bugpoint -run-jit

I am trying to use bugpoint to reduce the bytecode for a bug in one of my transformations. Normally I run opt as such: opt -load=libmine.so -mypass -param1 -param2 -o b.bc a.bc Here, -mypass specifies a pass and -param1 and -param2 are just parameters that -mypass uses. I added them using the command line parsing library that llvm supports. I tried running bugpoint with the following:

Hi all, I've been running into what appears to be an optimization bug in llvm, while compiling the latest ruby 1.9.3 with the latest llvm/clang 2.9 version. From hands on experimentation I do know that the gvn pass for the "vm.c" compilation is the culprit of the miscompilation (clang -O2/-O3 options produce the miscompilation, however -O1 is fine!). I've also tried to
