Hi, I don't see a way to convert an Instruction to a string or const char *, although '<<' works on it. http://llvm.org/doxygen/classllvm_1_1Instruction.html How to figure this out? Thanks. -- Regards, Peng

See http://llvm.org/doxygen/classllvm_1_1Instruction.html (the LLVM doxygen info on llvm::Instruction) for more details. I believe these methods describe whether memory is read/written in a way visible from the LLVM IR; I don't believe they'll take into account things like read/writes due to register spills created by the code generator....

Hi all, Would it be correct to say that the only instructions in LLVM IR that modify/access memory potentially are the following: (1) LoadInst : Ref (2) StoreInst : Mod (3) VAArgInst : Ref (?) (4) AllocaInst : Mod (5) MallocInst : Mod (6) FreeInst : Mod (7) CallInst : Mod/Ref ? Also, my earlier impression was that the GEP instruction only computes the effective address and does not

Hi Kenneth, Can you elaborate what you mean by instruction pointer value? Like the actual instruction with opcode and operands? With the sample code that I showed you, the instrucrtion pointer in the innermost for loop will have access to the following functions: http://llvm.org/doxygen/classllvm_1_1Instruction.html Alternatively, you can use the dump() operation to dump the instructions out. Unfortunately I don't know how to address your second question. That's stretching my knowledge in LLVM.

Thank you so much! What about discovering the instruction pointer value? Also, does anybody know how to embed an artifact as a resource in a binary? I'd like to have two text sections, and have one copied in from another binary.

...want some piece of advice regarding a LLVM pass. My particular problem is: There is a method bool patternDC::runOnFunction(Function &F) { ... if ( CC->operEquiv(icmpInstrArray[i], icmpInstrArray[j]) ) {...} ... } having the array elements of type Instruction* : http://llvm.org/doxygen/classllvm_1_1Instruction.html The called method is bool ifChecker::operEquiv(Instruction *I1, Instruction *I2) { ... } BUT I want to use the methods from class ICmpInst : clasa http://llvm.org/doxygen/classllvm_1_1ICmpInst.html inside operEquiv. I cannot do something like ICmpInst** II1 = dyn_cast<ICmpInst*>(I1)...
