This was an interesting post from another list I'm on. I think that with all of the echo cancellation discussion happening, that someone perhaps might be on the lookout for this type of software, so this post was well-timed for Asterisk uses. It is perhaps the case that those of you working on volume/echo/etc stuff might find this useful towards your goals. JT >To: [snip]

Hi, We are running 1.4.22 and have been experiencing problems with certain IVRs and DTMF Tone duration. We would like to be able to increase DTMF Tone duration by 50 to 100ms over what the user is pressing on his phone. We have a PRI test circuit and an analyer in between to measure tone duration. We have tried setting chan_dahdi.conf parameter 'toneduration', but that does not do

Sorry the 1st example I gave it bit lame, it is changed to following: // a[] is local array, no addr taken. die right after the loop for (i = 0; i < N; i++) { a[i] = ... /* s1 */ sum += a[i-1]; } S1 could be easily deleted if alias analyizer say a[i] and a[i-1].

Hi, In today meeting, Dan gave a very impressive talk about alias analysis. I had a question about the example in his slide, something like: for (i = 0; i < N; i++) a[i] = a[i-1] + 1; For the sake of convenience, let A1, A2 be a[i] and a[i-1] respectively. In Dan's design, Alias(A1, A2) would give "no alias", and in order to prevent A2 from being mistakenly moved out

is there any facility in icecast2 to log listner statistics and data usage to xml or json file so i can build reports on top of it?

...n what situations the Offset != 0. So I put an assertion right before line 359, saying "assert(Offset != 0)". It catches two cases in SingleSource test suite. I investigate one of them, the assertion is triggered when the llvm::getObjectSize() is called by instcombine (instead of alias analyizer) in an attempt to replace llvm.objectsize() with a constant. I think the way llvm::getObjectSize() interpret "object" is wrong. Figure 1 cat -n lib/Analysis/MemoryBuiltins.cpp 344 bool llvm::getObjectSize(const Value *Ptr, uint64_t &Size, const DataLayout *TD, 345...
