I just want firstly to compile helloworldmodule.c into
helloworldmodule.bc.<br>
Then I run a LLVM pass on it to do some optimization, and then I
compile the modified .bc file into .ko file.<br>
<br>
So, could you tell me how to compile helloworldmodule.c into
helloworldmodule.bc? I think it's not the same command <b>"clang
-O3 -emit-llvm hello.c -c -o hello.bc". </b>Because it is a
device driver that will be at last compiled to be .ko file.<br>

No, that's exactly how you would do it, although you might need to
use GCC + Dragonegg instead of clang because the Linux 3.0 kernel
doesn't compile with Clang out-of-the-box (at least for me, anyway).<br>

<div style="line-height:1.7;font-size:14px;font-family:arial"> Hi,
my friends<br>
<br>
<br>
I know there is a difference between compiling a linux
module and a simple helloworld programme.<br>
If I compile a helloworld.c file, the command is <br>
<b>"clang -O3 -emit-llvm hello.c -c -o hello.bc"</b><br>
But what the command should be if I want to compile a
linux module into a .bc file? (I know it may be an easy
question to you guys, but I really don't know where to
find the answer on <a moz-do-not-send="true" href="http://llvm.org" target="_blank">llvm.org</a>.)<br>

<div>What do you mean by linux module? A shared library
(.so)? A kernel module (.ko)?</div>
