Raw Normal View History

The UTF16 string referenced by a CFString should go into the __TEXT,__ustring section. A 'normal' string will go into the __TEXT,__const section, but this isn't good for UTF16 strings. The __ustring section allows for coalescing, among other niceties (such as allowing the linker to easily split up strings). Instead of outputting the UTF16 string as a series of bytes, output it as a series of shorts. The back-end will then nicely place the UTF16 string into the correct section, because it's a mensch. <rdar://problem/10655949> llvm-svn: 153710
