[LLVMdev] Create a call to function malloc using LLVM API
Hi, I encountered an issue when attempting to create a call to function
malloc.
I just want to do a simple thing, suppose there is a variable p, if p is a
pointer
then allocate memory to p.
Source code:
int *p;
p = (int *) malloc(sizeof(*p));
Try to generate LLVM IR for it:
Type *tp = p->getType();
AllocaInst* arg_alloc = builder.CreateAlloca(tp);//builder is IRBuilder
