What's the set of valid characters that can occur in an LLVM symbol name? The reason I ask is that my compiler is generating symbols based on method names. Some methods are operators, and I haven't got around to mangling the names yet. As a result it's producing symbols that look like _f_+ and _f_:=. LLVM seems to be coping fine with these so far and the IR output is quoting them, producing lines like: %7 = call fastcc i32 @"_f_+"(i8* %6, i32 1) Should I be mangling the names, or can I rely on LLVM to cope? If so, will LLVM correctly mangle the names itself to keep the platform assembler happy? -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ───── http://www.cowlark.com ───── │ "Thou who might be our Father, who perhaps may be in Heaven, hallowed │ be Thy Name, if Name Thou hast and any desire to see it hallowed..." │ --- _Creatures of Light and Darkness_, Roger Zelazny -------------- next part -------------- A non-text attachment was scrubbed...
