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, th...

While adding support for branch instructions in my backend, I run into a trouble. The code to handle branches looks like: void visitBranchInst(BranchInst& BI) { BB->addSuccessor (MBBMap[BI.getSuccessor(0)]); if (BI.isConditional()) BB->addSuccessor (MBBMap[BI.getSuccessor(1)]); ........... BuildMI(BB, NM::GOTO, 1).addPCDisp(BI.getSuccessor(0));...

All, So far I've tried LLVM on amd64, i386, ia64 and powerpc under FreeBSD and aside for ia64, things look pretty good for a first try. There are 2 unexpected failures for PowerPC, which appear to be caused by uninitialized memory. I'm still working on a fix for that (need to brush up on my C++ skills). [sidenote: In FreeBSD -current, the memory allocator initializes memory with 0xa5
