Your reasoning sounds correct to me. Let's revert for now? I don't think there is an easy fix, we'll have to do a global "must be executed" analysis to reapply the patch soundly. And that's difficult since any external functional call can call "exit(0)". -- Sanjoy On Thu, Sep 26, 2019 at 6:19 AM Tim Northover <t.p.northover at gmail.com> wrote: >

Hi Sanjoy, SCEV is behaving inconsistently when forming SCEV for this zext instruction in the attached test case- %conv5 = zext i32 %dec to i64 If we request a SCEV for the instruction, it returns- (zext i32 {{-1,+,1}<nw><%for.body>,+,-1}<nw><%for.body7> to i64) This can be seen by invoking- $ opt -analyze -scalar-evolution inconsistent-scev-zext.ll But when computing

Hi Sanjoy, >> I'm a bit apprehensive of adding more caching to solve problems created by caching; but if there is no way out of adding another cache, how about adding a cache that maps SCEV expressions to their simplified versions? Then we could do something like: I may be wrong but I think caching is not an issue in itself, but caching in the presence of self-recursion is. >>

Dear Speex developers I am going to port Speex on LPC2368 I tested Speex encoding and the mesurments shows ~40ms cpu time for one frame Do you know who ported speex to NXP or other 32bit platform?

Hi Sanjoy, Thanks for investigating the issue! I am more interested in getting the underlying problem fixed rather than making this particular test case work. I think I have more test cases where this problem crops up. I would any day prefer consistent results over compile time savings which can lead to inconsistencies. These inconsistencies require significant developer time to analyze and fix

Hi, +CC Max, Serguei This looks like a textbook case of why caching is hard. We first call getZeroExtendExpr on %dec, and this call does end up returning an add rec. However, in the process of simplifying the zext, it also calls into isLoopBackedgeGuardedByCond which in turn calls getZeroExtendExpr(%dec) again. However, this second (recursive) time, we don't simplify the zext and cache a

This sounds fine to me (and sorry for the delay!). -- Sanjoy On Mon, Mar 12, 2018 at 1:09 PM, Chawla, Pankaj <pankaj.chawla at intel.com> wrote: > Hi Sanjoy, > > So what is the verdict on this issue? > > Thanks, > Pankaj > > > -----Original Message----- > From: Chawla, Pankaj > Sent: Monday, February 26, 2018 11:12 AM > To: Sanjoy Das <sanjoy at

Greetings: I am trying to work with spdep (everything is "brand new" downloaded this morning). OS = Windows 2000 (also up to date). The code I am using follows: #example gal.county=read.geoda("lnpilnd.GAL", row.names=NULL, skip=0) summary.nb(gal.county) Error in summary.nb(gal.county) : Not a neighbours list #end The gal file works just fine in GeoDa (also up to date).

I don't have cycles for this right now, but if you file a bug I can give this a shot when I have time later.
