llvm dev - Jul 2014 - [LLVMdev] LLVM Problem

Hello,

I am a presently doing undergraduate studies at IIIT-Delhi and have been
trying to install LLVM and facing some issues installing it which you guys
could help resolving. I am able to generate the byte code but unable to
generate the assembly code from the byte code. Below is the commands that I
executed along with the error.



clang hello.c -o hello
clang -O3 -emit-llvm hello.c -c -o hello.bc
llvm-dis < hello.bc | less
or
llc hello.bc -o hello.s
on running any of the last two lines I am getting an error which I an
unable to resolve and understand:

llvm-dis: invalid module_code_globalvar record

Hoping for an early response.

Thanks

Hi,

As a first step you can try emitting LLVM assembly directly rather than
using llvm-dis

$ clang -O3 -emit-llvm hello.c -S -o hello.ll

You're more likely to get help if you provide more information.

* What version of LLVM and clang are you using? E.g. from trunk? You should
also be careful not to mix LLVM and clang versions (e.g. a bitcode file
produced by clang 3.2 might not work properly with LLVM 3.4)

* What are the contents of hello.c?
If you don't provide the source file nobody apart from you can try to
reproduce the issue.

Thanks,
Dan
