...y pass inserts a call to this function. But I don't have any problems with my pass if I run clang -emit-llvm -S, then llc and then gcc. With this approach I get a binary with my instrumentation inserted. This line causes a problem - assert((i >= FTy->getNumParams() || FTy->getParamType(i) == Args[i]->getType()) && "Calling a function with a bad signature!"); I tried to get a dump of FTy->getParamType(i) and Args[i]->getType(), but I wasn't able to do it in gdb - everytime I create a breakpoint it just misses it. So I made the following...

The first buildbot failure I can readily find was Monday, 26oct2009 around 7PM PDT. The assertion is Assertion failed: ((i >= FTy->getNumParams() || FTy->getParamType(i) == Params[i]->getType()) && "Calling a function with a bad signature!"), function init, file /Volumes/Sandbox/Buildbot/llvm/ build.llvm-gcc-x86_64-darwin10-selfhost/llvmCore.roots/llvmCore~obj/ src/lib/VMCore/Instructions.cpp, line 312.

When for example some call is wrong error message always looks like this: Assertion failed: ((i >= FTy->getNumParams() || FTy->getParamType(i) == Params[i]->getType()) && "Calling a function with a bad signature!"), function init, file /tmp/llvm-svn/llvm/lib/VMCore/Instructions.cpp, line 247. I believe assert() statements should better be replaced with more detailed printouts of what is wrong. This will save m...

Hi! I have this error while building my code: Assertion failed: ((i >= FTy->getNumParams() || FTy->getParamType(i) == Params[i]->getType()) && "Calling a function with a bad signature!") Actually I'm trying to load functions from .bc file and use them in the code that I'm building with IRBuilder. I found that function parameter type is %struct.reValue* and the type of the value...

Hi all, I am creating a function and trying to call it using the LLVM API. It seems that whenever the function type includes an opaque-typed parameter, the CallInst::Create call causes an assert: Assertion failed: ((i >= FTy->getNumParams() || FTy->getParamType(i) == Params[i]->getType()) && "Calling a function with a bad signature!"), function init, file /usr/home/csanchez/shared/prj/tce/ src/llvm-2.5/lib/VMCore/Instructions.cpp, line 294. If I change the code so the function type has only non-opaque types, everything is corr...

Hi! Attached patches split init.trampoline into adjust.trampoline and init.trampoline, like in gcc. As mentioned in the previous mail, I've not made a documentation patch, since I'm not sure about what the documented semantics of llvm.adjust.trampoline should be.

...%323 to a library function whose prototype is: recordStore(const char*, unsigned int, unsigned, int) But my passer stuck at CallInst::init, because llvm complains %323 does not have the same type as the recordStore's is declared. assert((i >= FTy->getNumParams() || FTy->getParamType(i)== Params[i]->getType()) && "Calling a function with a bad signature!"); This is strange because the fourth argument of recordStore has been declared as: "IntegerType::get(getGlobalContext(), 32)" If I somehow replace the assert statement as: assert(.....
