Nick Kledzik e93da60ac4 [Support] Add type-safe alternative to llvm::format() ... llvm::format() is somewhat unsafe. The compiler does not check that integer parameter size matches the %x or %d size and it does not complain when a StringRef is passed for a %s. And correctly using a StringRef with format() is ugly because you have to convert it to a std::string then call c_str(). The cases where llvm::format() is useful is controlling how numbers and strings are printed, especially when you want fixed width output. This patch adds some new formatting functions to raw_streams to format numbers and StringRefs in a type safe manner. Some examples: OS << format_hex(255, 6) => "0x00ff" OS << format_hex(255, 4) => "0xff" OS << format_decimal(0, 5) => " 0" OS << format_decimal(255, 5) => " 255" OS << right_justify(Str, 5) => " foo" OS << left_justify(Str, 5) => "foo " git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218463 91177308-0d34-0410-b5e6-96231b3b80d8		2014-09-25 20:30:58 +00:00
