Hi Danny, // Add TypeBasedAliasAnalysis before BasicAliasAnalysis so that // BasicAliasAnalysis wins if they disagree. This is intended to help // support "obvious" type-punning idioms. - if (UseCFLAA) - addPass(createCFLAliasAnalysisPass()); addPass(createTypeBasedAliasAnalysisPass()); addPass(createScopedNoAliasAAPass()); + if (UseCFLAA) +

Hello list, Excuse me for my poor english. I have updated on a test server dovecot 2.0.13 to dovecot 2.1.1. All works fine, but with the new version it seems that dovecot don't do hardlinks when deliver a message to multiple users. I have checked my config and the only rule I can see aboout that is maildir_copy_with_hardlinks = yes in /etc/dovecot/conf.d/10-mail.conf My mail location

So, I can make all these testcases work, but it's a little tricky (it involves tracking some things, like GEP byte range, and then checking bases and using getObjectSize, much like BasicAA does). Because i really don't want to put that much "not well tested" code in a bugfix, and honestly, i'm not sure we will catch any cases here that BasicAA does not, i've attached a

Updated testcases to have MayAlias/note issues as FIXME.

> Should we be added an edge from the inttoptr to all other pointer values? Is there a better way? We can add a special "Unknown" StratifiedAttr and query it before anything else, i.e: // in CFLAliasAnalysis::query, as the first potential return if (AttrsA[AttrUnknown] || AttrsB[AttrUnknown]) return MayAlias; The only *potential* issue with this approach would be that in the

Hey all, Alright. So we decided to not go with Avaya for our next PBX and we are now full on into an Asterisk/Lync 2010 implementation. Asterisk/FreePBX is our SIP gateway and call center and Lync is our internal UC and IP-PBX server. I've already got Asterisk tied with our Nortel/Merridian Option 11 with QSig and all is beautiful (except for the Opt11 not receiving names from * but

Without the patch is also returns the wrong answer for all of these, it just doesn't cause LICM to promote because it returns PartialAlias (which is still wrong). We return may-alias instead, and now suddenly it's happy to promote them. The broken noalias results exist both before and after my patch: ===== Alias Analysis Evaluator Report ===== 521 Total Alias Queries Performed

No, i mean the actual store instruction looks like "store i16 %conv22, i16* getelementptr inbounds ([16 x i16]* @pA, i64 0, i64 12), align 2, !tbaa !1" Not that the pointer operand comes from a GEP, but it is a constantexpr, whose opcode is GEP. It sucks that there is such a complex thing to be handled as a store operand directly , but such is life ... CFL-AA *should* treat this

> Fixing that still gives a wrong result, i haven't started to track down what *else* is going on here. Running with the attached diff + a modified buildGraphFrom to handle the constexpr GEPs, we seem to flag everything in test2.ll (conservatively) correctly. Is `store` the only place we can expect to see these constexpr analogs, or is just about anywhere fair game? George On Fri, Jan
