[LLVMdev] problem with visitBranchInst()

[Jun Koi]

hi,

my code inherits InstVisitor class, and visitBranchInst() method.

however, i notice that inside the virtual method
visitBranchInst(BranchInst &I), on the LLVM instruction like:

br i1 %1, label %2, label %3

my code doesnt return expected info. for ex, the code

I.getCondition->getName().str()

would return empty string. and at the same time, the code

I.getSuccessor(0)->getName()

would also return emtpy string.

i am pretty confused, as i am expecting non-empty strings returned
from the above functions.
any idea on why this happens?

this is on LLVM 3.0, Ubuntu 12.04.

thanks so much,
Jun
