Hello everyone: I have a little question about the second argument *action* of verifyFunction. In docs: *Enumerator: * *AbortProcessAction* verifyModule will print to stderr and abort() *PrintMessageAction* verifyModule will print to stderr and return true *ReturnStatusAction* verifyModule will just return true But it still abort when I pass PrintMessageAction/ReturnStatusAction to function. Log: Basic Block in function 'jit...

I followed what you said and called verifyModule() with the AbortProcessAction option. verifyModule() returns false, but does not abort and does not print out any information about what caused the verification to fail.

I also tried iterating through the functions of the module and calling verifyFunction(), which also returns false, but does not cause an abort or report anything to stderr about what caused the verification to fail. From the doxygen for verifyFunction() and verifyModule(), it seems like they both should print information to stderr if the verification fails and should abort opt if AbortProcessAction is passed as parameter. Is this a bug? Ryan M. Lefever wrote: > I followed what you said and called verifyModule() with the > AbortProcessAction option. v...

I think I misread the doxygen. verifyFunction & verifyModule return false if no errors are detected. However, my question now becomes why does the code produced by my transform pass verification, but it causes an assertion failure in the byte reader when it (the code produced by my transform) is passed to another invocation of opt?

...ret void } attributes #0 = { alwaysinline } Clearly, if this is processed with opt -alwaysinline, it will lead to a correct tail call since the call to "tobeinlined" will be inlined. However, because opt checks for the correctness of the module when it is being loaded, it fails the verifyModule() check with: cannot guarantee tail call due to mismatched parameter counts musttail call fastcc void @tailcallee(i32 3) opt: prelude.inlined.ll: error: input module is broken! These are just experiment, but I suspect that I will have the same problem when I am constructing IR with the LLVM AP...

As the module grows, it takes longer to verify. So, I will disable this for now. Simon. -- Simon Burton,...

I guess that you are not using `verifyModule' before generating the native code, because the sort of declaration/call mismatch you are experiencing is detected there. Or you are calling the external vaarg function with the same number of parameters listed on the faulty declaration, in which case `verifyModule' has no reason for compla...

Such as printf, etc., from IR created using the API (IRBuilder). Google hasn't provided much help, and I can't find anything relevant in the docs (the docs talk about how to do varargs in LLVM ASM, but not how to call an external vararg function that exists in a library that gets linked to the LLVM module). Is there something special I need to do? Simply calling

Besides, which version of llvm are you using? What are the commands for compiling and linking your test case? How it bombs? Do you #include "llvm/ExecutionEngine/JIT.h" ? -- Oscar

It slows in the construction phase, so one of these calls: M = ParseAssemblyString(AsmString, M); verifyModule( *M ) M->getNamedFunction(name); EE->getPointerToFunction It feels like there is a linear name lookup going on somewhere.
