The hardware loop code tries to evaluate the iteration count, and when it fails to do so, it skips the loop. The complication with unsigned overflow as a loop exit condition is that it makes calculating of the iteration count harder, and the current code for hardware loop doesn’t handle it. It should be possible to expand it, but it would be a non-trivial amount of work. Instead, I decided to rewrite the simple cases of unsigned add/sub, where the overflow condition can be rewritten in a way that is currently recognized.<o:p class=""></o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">Varying increments are not translatable into a hardware loop, but increments that are not 1 are, as long as we can calculate the iteration count (the hardware loop instruction takes a register containing the iteration count as an operand). My guess is that if there was a loop with a non-unit increment, whose exit condition was an unsigned overflow, that loop would not have been handled by the hardware loop generation to begin with, so only dealing with +/-1 should be sufficient. In the long term improving the hardware loop generation would be a better approach, but it’s more work.<o:p class=""></o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div><div class=""><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="font-size: 9pt; font-family: Consolas;" class="">--<span class="Apple-converted-space"> </span></span><span style="font-size: 9pt; font-family: Consolas;" class=""><o:p class=""></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><span style="font-size: 8pt; font-family: Consolas;" class="">Krzysztof Parzyszek <span class="Apple-converted-space"> </span><a href="mailto:kparzysz@quicinc.com" style="color: purple; text-decoration: underline;" class=""><span style="color: rgb(5, 99, 193);" class="">kparzysz@quicinc.com</span></a> LLVM compiler development<o:p class=""></o:p></span></div></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div><div class=""><div style="border-style: solid none none; border-top-width: 1pt; border-top-color: rgb(225, 225, 225); padding: 3pt 0in 0in;" class=""><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><b class="">From:</b><span class="Apple-converted-space"> </span>Joan Lluch <<a href="mailto:joan.lluch@icloud.com" style="color: purple; text-decoration: underline;" class="">joan.lluch@icloud.com</a>><span class="Apple-converted-space"> </span><br class=""><b class="">Sent:</b><span class="Apple-converted-space"> </span>Tuesday, July 2, 2019 8:45 AM<br class=""><b class="">To:</b><span class="Apple-converted-space"> </span>Krzysztof Parzyszek <<a href="mailto:kparzysz@quicinc.com" style="color: purple; text-decoration: underline;" class="">kparzysz@quicinc.com</a>><br class=""><b class="">Cc:</b><span class="Apple-converted-space"> </span><a href="mailto:llvm-dev@lists.llvm.org" style="color: purple; text-decoration: underline;" class="">llvm-dev@lists.llvm.org</a>; Sanjay Patel <<a href="mailto:spatel@rotateright.com" style="color: purple; text-decoration: underline;" class="">spatel@rotateright.com</a>><br class=""><b class="">Subject:</b><span class="Apple-converted-space"> </span>[EXT] Re: [llvm-dev] [hexagon][PowerPC] code regression (sub-optimal code) on LLVM 9 when generating hardware loops, and the "llvm.uadd" intrinsic.<o:p class=""></o:p></div></div></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">Hi Krzysztof,<o:p class=""></o:p></div><div class=""><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div></div><div class=""><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">Thank you very much for such a quick reaction.

However, after looking at it I have a question about it. My understanding is that your code only replaces uaddo, usubo with ‘1’ as the second operand. This certainly solves the hardware loop problem and I assume it’s enough, as there’s no possible loops with scalable increments?<o:p class=""></o:p></div></div><div class=""><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div></div><div class=""><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">I also want to mention that based on the reply I received from Sanjay, I also tried to override ‘shouldFormOverflowOp’ to always return false. This also solves the issue, but of course it prevents the ‘.with.overflow’ intrinsics to be generated at all. My understanding is that this fully mimics LLVM 7.0 behaviour, but I do not have the required knowledge on Hexagon to give an opinion about whether this is useful.

However, LLVM 9 can’t identify a Hardware loop pattern due to the odd C2_cmpgtu instruction that gets generated. This instruction is a consequence of the introduction of the “llvm.addu” intrinsic that I showed earlier.</span><o:p class=""></o:p></div></div></div><div class=""><div class=""><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; background-color: white;" class=""><span style="font-size: 9pt; font-family: Helvetica, sans-serif;" class=""> </span><o:p class=""></o:p></div></div></div><div class=""><div class=""><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; background-color: white;" class=""><span style="font-size: 9pt; font-family: Helvetica, sans-serif;" class="">I am presenting here the case of Hexagon, but I suspect the same sub-optimal code may happen for the PowerPC (not checked yet).</span><o:p class=""></o:p></div></div></div><div class=""><div class=""><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; background-color: white;" class=""><span style="font-size: 9pt; font-family: Helvetica, sans-serif;" class=""> </span><o:p class=""></o:p></div></div></div><div class=""><div class=""><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; background-color: white;" class=""><span style="font-size: 9pt; font-family: Helvetica, sans-serif;" class="">All the code excerpts were obtained with -Os flags</span><o:p class=""></o:p></div></div></div><div class=""><div class=""><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; background-color: white;" class=""><span style="font-size: 9pt; font-family: Helvetica, sans-serif;" class=""> </span><o:p class=""></o:p></div></div></div><div class=""><div class=""><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; background-color: white;" class=""><span style="font-size: 9pt; font-family: Helvetica, sans-serif;" class="">I’m highly interested in getting in contact with someone familiar with the Hexagon/PowerPC targets regarding this subject.
