[LLVMdev] Minimum Array Size

[Hal Finkel]

Hello,

clang currently seems to generate the same code for both:

double something_a(char A[const static 256]) {
  ...
}

and for:

double something_b(char (*const A)) {
  ...
}

even though in the first case the programmer has told us that the array
A is at least 256 bytes in length (and, thus, will not be null). Do we
currently have a way to pass this information to LLVM?

Thanks again,
Hal
