...corresponding suite. d. Next Steps: Add a Geomean button to plot the geomean of all the workloads instead of separate plots for each workload. If you feel that some of these improvements are valuable, then I can create patches and upload them in Phabricator for review. Thanks!

...or the loop with unknown trip count. Loop unrolling is disabled when TC > 0. Should this be changed to TC >= 0 (which does the job for this testcase)? Or is there a better way to disable loop unrolling for such trivial loops, at least the ones with known array size?

Hi Sriram, Thanks for performing this analysis. The problem here, both for memcpy and the vectorizer, is that we can’t predict the size of “n”, even though the only use of ’n’ is for the loop bound for the alloca [4 x [8 x i32]]. If you change the unroll condition to TC >= 0 then you will disable loop u...

...not have SSE enabled for my sub-target, and llvm resorts to fcomi* instructions for FP compare instructions. Is there a way to bypass the automatic optimization that generates the x87 instructions when SSE is disabled, and completely eliminate the code generation for the same(error out)?

Sriram, The problem is that you want to unroll/vectorize many loops with non-constant loop count - it is a trade-off of which case you estimate as more likely. int foo(int *ptr, int n) { for ( .. i <n) ptr[i] = ... } The question is: is it more likely to have “n” such that unrolling is benefi...

...ever it mounts the volume as root. But if I use the ocfstool for the first and mount it as oracle:dba, the subsequent mounts using the above command line mounts the volume as oracle:dba. Is there something that I am missing or I will have to only use the ocfstool for the first time. Regards Sriram -------------- next part -------------- An HTML attachment was scrubbed...

Hi Sriram, I'm not sure if I understand your question correctly: Do you need to generate code that contains no x87 floating-point instructions altogether, but uses calls into a soft-float library instead? That behaviour can be enabled using the "-soft-float" flag, as far as I know. Or is it o...

Hi I am using Trixbox 2.4 and PRI lines..on the CDR i see many calls that have duration of 0 seconds, but they are still shown as ANSWERED . how come its possible when duration is 0.00 ? Are the callers billed for such calls ? Rgds Sriram -------------- next part -------------- An HTML attachment was scrubbed...

...this is addressed using a simple heuristic. For that, we need to identify the loop cost and decide if it makes sense to completely unroll the loop, or partially unroll. I am unsure of the optimal way to implement this though. I want to run it by the list to get any ideas floating around :) Thanks Sriram -----Original Message----- From: Arnold Schwaighofer [mailto:aschwaighofer at apple.com] Sent: Friday, September 27, 2013 1:54 PM To: Murali, Sriram Cc: llvmdev at cs.uiuc.edu Subject: Re: [LLVMdev] Trip count and Loop Vectorizer On Sep 27, 2013, at 12:47 PM, Arnold Schwaighofer <aschwaighof...

The question is how often does such an example occur, where this is possible, to make such an effort justifiable? smaller equal, of course ;)

...r a billion times shows quite some performance difference on gcc against clang Gcc - 8.6 seconds Clang - 12.7 seconds Evidently, the addition operation can be vectorized to use addps, (clang does addss), and the loop can be unrolled for better performance.
