pass example.<br>

<div style="direction:ltr; font-family:Tahoma; color:#000000; font-size:10pt">Hmmm, I just thought of something. Perhaps I need to set the MODULE cmake flag (via -DMODULE=ON)? I will try this today. (I remembered the LOADABLE_MODULE=1 flag in the makefile,
and the if ( MODULE ) check in the AddLLVM cmake module.)<br>

<div>After building the pass out of source with cmake, when I load it with opt, I get an undefined symbol error: _ZTIN4llvm12FunctionPassE undefined in the .so.
<br>
<br>
(_ZTVN4llvm12FunctionPassE is also undefined -- a "U" when I run nm. This symbol -is- in all of the llvm libraries.)<br>
<br>
Platform: ubuntu 12.10 LTS, x86 64<br>
gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3<br>
<br>
Build: LLVM 3.2 (svn), tried debug and release<br>
</div>
<div>Test suite builds and runs without error<br>
No other versions of llvm or clang are present<br>
</div>
<div><br>
I also tried building debug and release versions of the pass. No build errors or warnings when producing the pass .so.<br>
<br>
</div>
<div>I don't see this symbol in any of the llvm libraries, so I have no idea how it is being introduced into the pass .so.<br>
<br>
</div>
Interestingly, when I build llvm in source with autotools, and build the pass in source with the provided makefile template, it works, and _ZTIN4llvm12FunctionPassE is not in the pass .so. (Also, _ZTVN4llvm12FunctionPassE is now "B" when I run nm.).
