Hi all, I'm still struggling with getElementPtr. I have a global variable (array of doubles). I can use ConstantExpr::getGetElementPtr(myGlobalVariable, indices) and use the result as argument of e.g. a function. I read the GEP docu and know that I need anextra leading '0' index to dereference the global's pointer. So far so good. But I can not succeed in using the

Hi Tim, I forgot to say that I try to do all this in the LLVM API, not IR. I read in a bc'ed program and try to edit it using the API.

HI all, in C/C++, arrays and matrices often are passed as pointer so functions. Suppose I'd like to write a pass operating on arrays , for example an array of doubles passed via double * and checking for the type i will identify a pointer to double (isAggregateType()=false). As this style of passing arrays using pointers is widely used, I wonder if there is any chance to identify a pointer
