[LLVMdev] int to StringRed conversion

[Logan Chien]

Hi,

  I think you may try to use llvm::Twine(int).  For example, to convert 30
to string, you can use:

Twine(30).str()

To convert the string back to integer, you can try the
StringRef::getAsInteger(unsigned, APInt &).  For example:

APInt i;
str.getAsInteger(/*radix=*/ 10, /*output=*/ i);

Sincerely,
Logan
