[LLVMdev] memcpy function in LLVM

[maryam raiyat]

Hi, 
II understood that LLVM uses the term " llvm.memcpy.p0i8.p0i8.i64" for memcpy function, and the term " llvm.memmove.p0i8.p0i8.i64" for memmove function.  but the considerable point is that IR code shows that LLVM not only uses "llvm.memcpy.p0i8.p0i8.i64" for memcpy function , but also for arrays like  char x[100] !!! This means custom instruction selector for memcpy functions monitors all arrays of source code as memcpy function. But, for memmove function it is not the same. Am I right? what should I do ti fix this problem?
Thanks
