Thanks! I'll commit the hexdigit() change separately.
================
Comment at: llvm/include/llvm/ADT/StringExtras.h:37
inline char hexdigit(unsigned X, bool LowerCase = false) {
- const char HexChar = LowerCase ? 'a' : 'A';
- return X < 10 ? '0' + X : HexChar + X - 10;
+ assert(X <= 16);
+ static const char *const LUT = "0123456789ABCDEF";
----------------

D'oh, yes of course. Thanks for spotting that!
================
Comment at: llvm/include/llvm/ADT/StringExtras.h:38
+ assert(X <= 16);
+ static const char *const LUT = "0123456789ABCDEF";
+ const uint8_t Offset = LowerCase ? 32 : 0;

Yes that would work, but I think it's simpler to just use the built-in types
here.
Actually, there's no need for this to be a pointer, it should just be an array.
I'll fix that.
