...-functionattrs gets a 'readnone' on @store's %p. That's wrong, it clearly stores to it. The bug is due to incorrectly handling the copy of the pointer made by @get_pntr, because @get_pntr itself is marked 'readnone'. Please file a bug.

...rough a different pointer. So before I try to fix GVN, my question is, am I on the right track? Specifically, is the definition in the LangRef correct? Thanks, Rob. P.S. GVN's checking of the attributes is done in AliasAnalysis::callCapturesBefore in lib/Analysis/AliasAnalysis.cpp -- Robert Lougher SN Systems - Sony Computer Entertainment Group

Howdy, Was there ever a fix for this? I have Trix 2.6 running asterisk 1.4 and have to set an extension with call-limit=1. However that user can no longer do attended transfers from Linkys 962 ip phone. Is there anyway around this? Cheers, Taff..

Greetings all, As you may have noticed, there is a new vector shuffle lowering path in the X86 backend. You can try it out with the '-x86-experimental-vector-shuffle-lowering' flag to llc, or '-mllvm -x86-experimental-vector-shuffle-lowering' to clang. Please test it out! There may be some correctness bugs, I'm still fuzz testing it to shake them out. But I expect fairly few

Howdy, How do i perform a lookup from a remote odbc database in the asterisk dialplan? I can do it with mysql but not sure of commands for odbc connection. Cheers!!!
