<pre>Hello,
In lib/Transforms/Utils/SimplifyCFG.cpp, function 'SpeculativelyExecuteBB()',
when we create a new SelectInst (named 'spec.store.select') and make it operand
0 of the speculated store instruction, why do we need to modify the debug
location of the speculated store?
IIUC, the debug location of the speculated store should not be changed: the
debug location of the branching instruction is already attached to the
SelectInst.
Thanks for your time</pre>
