[Thomas Preud'homme via Phabricator via cfe-commits]

thopre added inline comments.


================
Comment at: llvm/lib/Support/CommandLine.cpp:95
+
+static size_t argPrefixesSize(size_t len) {
+  if (len == 1)
----------------
Any reason why not take a StringRef of the option to compute the prefix of? That would put the .size() gymnastic in one place instead of many.


================
Comment at: llvm/lib/Support/CommandLine.cpp:101
+
+static StringRef argPrefix(size_t len) {
+  if (len == 1)
----------------
Likewise.
