<div dir="ltr"><div>I see. Is Bill Wendlign still active ? Maybe he has some comment on this.<br><br></div>So what needs to be done is basically have a C interface to manipulate attribute sets ? Is there any pitfall I may not be aware of, or is this not done simply because nobody has the time to do it ?<br>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">The larger picture is that LLVM IR supports arbitrary string attributes, and a bitmask is no longer an appropriate representation for attributes. Bill Wendling never extended the C API to support this. Furthermore, we have more than 32 known, single-bit, enum attributes, so even if we ignore string attributes, a 32-bit bitmask is insufficient.</div>
