Link to "The use of multirate filter banks for coding" by T. Sporer, K. Brandenburg and B. Edler
Hello, In the "Documentos" section SanJaaC Electronics' website you can now find a zipped version of the paper "The use of multirate filter banks for coding of high quality digital audio" by T. Sporer, K. Brandenburg and B. Edler. I hope this helps to relieve the shortcoming with the -404 error message when trying to access it form other sites. Please let me know if I am incurring in some sort of copyright trouble. All what I want to do is to share it with people who might need it for research/education/development purpos...

[LLVMdev] BasicAA unable to analyze recursive PHI nodes
Hi all, I came across the following limitation in our BasicAliasAnalysis. This happens with the following IR pattern: %x = phi [ %incptr, ... ] [ %var, ... ] %incptr = getelementptr %x, 1 We will basically always return MayAlias for %x and any other value because aliasPHI recurses on the first value and gives up. There are, however, many cases where this is too conservative. Take the

compiling problems
Hi, When I compile * with just make I get problems, I can't ring the phonejack PCI I have installed but when I compile with make valgrind I don't have problems ringing the PhoneJack. Anyone has been through this? Maybe that's a Dev list question, anyone on that list could please forward it to them? Cheers, -P -- __________________________________________________________ Sign-up
