From 6cf081cbe5963d6e1b12b0ac1268538a38acd0f1 Mon Sep 17 00:00:00 2001 From: Lenny Maiorani Date: Thu, 28 Apr 2011 20:20:12 +0000 Subject: Remove bounded StringRef::compare() since nothing but Clang SA was using it and it is just as easy to use StringRef::substr() preceding StringRef::compare() to achieve the same thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130430 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Support/StringRef.cpp | 21 --------------------- 1 file changed, 21 deletions(-) (limited to 'lib/Support') diff --git a/lib/Support/StringRef.cpp b/lib/Support/StringRef.cpp index 066e774..8c3fc09 100644 --- a/lib/Support/StringRef.cpp +++ b/lib/Support/StringRef.cpp @@ -29,27 +29,6 @@ static bool ascii_isdigit(char x) { return x >= '0' && x <= '9'; } -/// compare - Compare two strings; the result is -1, 0, or 1 if this string -/// is lexicographically less than, equal to, or greater than the \arg RHS. -/// This is different than compare with no size specified as it only -/// compares at most the first n bytes. -int StringRef::compare(StringRef RHS, size_t n) const { - // Check the prefix for a mismatch. - size_t maxToCmp = min(Length, RHS.Length); - maxToCmp = min(maxToCmp, n); - if (int Res = memcmp(Data, RHS.Data, maxToCmp)) - return Res < 0 ? -1 : 1; - - // Otherwise the prefixes match, so we only need to check the lengths. - // Be mindful that if the n is less than or equal to the length of either - // string, that is the same as the strings matching because in that case - // we only care about the prefix. - if (((n <= Length) && (n <= RHS.Length)) || - (Length == RHS.Length)) - return 0; - return Length < RHS.Length ? -1 : 1; -} - /// compare_lower - Compare strings, ignoring case. int StringRef::compare_lower(StringRef RHS) const { for (size_t I = 0, E = min(Length, RHS.Length); I != E; ++I) { -- cgit v1.1
