Hi! <span title="Search for suggestions">Thanks</span> a lot for your sharing!!!

</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt">
The arbitrary integer type you extended is exactly what I am trying to implement. However, the solution to dealing with the source code with arbitrary precision integer, which I am trying to implement at the IR level, is quite ugly, since I am new to Clang
infrastructures.<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt">
Your extension is really helpful for people who deal with FPGAs and the source codes for High-Level Synthesis!!!</div>

<p class="x_MsoNormal"><span style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:#1F497D">A little more than a year ago, I created an arbitrary precision integer for an internal customer, and have now been cleared to release this to community.
I’m hoping that this will be sufficiently interesting to others to be of value.</span></p>

<p class="x_MsoNormal"><span style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:#1F497D">The “elevator pitch” is that we expose the iN LLVM-IR integer types in Clang such that a sufficiently motivated code generator could take advantage of the
smaller sizes. This is particularly useful for FPGAs, though I’d imagine other users are around.</span></p>
