[llvm-dev] Swift to IR, generates wrong IR

[Rinaldini Julien via llvm-dev]

Sorry, the error is (the previous one was from Apple’s lli):

Documents/strong.codes/code/build/obfuscator-llvm/bin/opt: test.ll:57:203: error: expected comma after getelementptr's type
@_METACLASS_DATA__TtC4test13TipCalculator = private constant { i32, i32, i32, i32, i8*, i8*, i8*, i8*, i8*, i8*, i8* } { i32 129, i32 40, i32 40, i32 0, i8* null, i8* getelementptr inbounds ([25 x i8]* @7, i64 0, i64 0), i8* null, i8* null, i8* null, i8* null, i8* null }, section "__DATA, __objc_const", align 8
