Hi all,</div>

I am handling some arbitrary precision integers (e.g. 13-bit) in the source code with Clang. Temporary, I declare them as structs like:</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">

<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
struct APINT13 VarA;</div>

<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
and during parsing the AST and generating IR, I transform the type of these variables into arbitrary precision integers.
<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
I read some other documentations and find that adding attributes for variables could be a nicer way to handle arbitrary precision integer.</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
However, as default, there is no such attribute as "bitwidth" in Clang. I found the following link and get some hints but the instructions listed in the website require me to modify the source code of Clang ("Attr.td", "include/clang/Sema/ParsedAttr.h"
and "utils/TableGen/ClangAttrEmitter.cpp").</div>

I just wonder whether there is any way to add attributes like plugins without touching the source code of Clang, because to rebuild Clang could be time-consuming. As I know, LLVM passes can work as plugins and I guess there could be the similar way to handle
attribute addition with Clang.</div>

Thanks in advance for your time and suggestion! \^_^/<br>
