Hi,
I have written a pass to compute the reaching definitions for variables
using loads and stores. The class for this pass is named ReachingDef and the
pass itself is registered as reaching-def. The compiled reaching-def.so file
goes to llvm-home/Release/lib/. This pass is used by another function pass
that is registered as iel and the class is named SIL. I have setup
AnalysisUsage
object of SIL by doing the below:
AU.setPreservesAll();
AU.addRequired<*ReachingDef*>();
AU.addRequired<*some other pass*>();
When I load the pass iel, I get the following error:
opt -load ../../../Release/lib/*iel*.so
<premain>: CommandLine Error: Argument 'inline-threshold' defined
more than
once!
opt: CommandLine Error: Argument 'inline-threshold' defined more than
once!
*Error opening '../../../Release/lib/iel.so':
../../../Release/lib/iel.so:
undefined symbol: _ZTI11ReachingDef
-load request ignored.
*
It looks like the ReachingDef pass is not being recognized. Please tell me
how to fix this.
Thanks

Thank you for the answer. That worked. I had defined another pass but I had actually installed that with the rest of llvm but that was quite some time back. Since I was not adding "-load" for that, I thought its not needed for reaching-def as well.
