when run occurs error

[beizishaozi]

Hi,
when I try to generate LLVM IR for a binary, it cause errors as follows:
anna@ubuntu:/llvm/build/llvm/bin$ gcc hello.c
anna@ubuntu:/llvm/build/llvm/bin$ ./llvm-mctoll -d a.out
llvm-mctoll: /home/anna/llvm/src/llvm/tools/llvm-mctoll/MachineFunctionRaiser.cpp:264: bool ModuleRaiser::collectDynamicRelocations(): Assertion `(DotRelaDotPltShdr.get()->sh_info == DotGotDotPltSec.getIndex()) && ".rela.plt does not refer .got.plt section"' failed.

besides, the OS is "Linux ubuntu 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux"

I don't know where is the problem. Could you give me some suggestions?
best regards

Thanks for trying the tool and for reporting the failure.

This failure was fixed with commit 21218e9 a couple of days ago.

Is it possible that your sources need to be updated?

Please let me know if you see the problem even with the tip of the tree.

Looking at the OS version you included, it appears that you may be running on an older Linux distro (may be Ubuntu Trusty?? 14.04??) and hence are using older compiler and binutils. llvm-mctoll has not yet been tested on that distro. Support for any codegen and/or ELF binary packaging differences needs to be added.

As noted in README.md, at present development and testing is being done using Ubuntu 18.04. It is expected that build and test would work on Ubuntu 16.04, 17.04 and 17.10.
