There is a phi-node "%phi = phi i64 [%cast1, %if], [%cast2, %else]" in the common successor. The actual control flow is a bit more complex, but there is a common successor block, and %cast1 and %cast2 are the two values that the phi node in the common successor takes. Does the existence of the phi node affect optimization? Thanks, Taewook From: &l...

...ir common predecessors. For example, for the following code snippet pred: … br i1 %cmp, label %if, label %else if: %incdec.ptr.1 = getelementptr inbounds i8, i8* %ptr, i64 1 %cast1 = ptrtoint i8* %incdec.ptr.1 to i64 … else: %incdec.ptr.2 = getelementptr inbounds i8, i8* %ptr, i64 1 %cast2 = ptrtoint i8* %incdec.ptr.2 to i64 GVN doesn't move instructions in 'if' and 'else' blocks to 'pred' block even though it knows that incdec.ptr.1/case1 has a same value number with incdec.ptr.2/cast2. I see a case where this kind of redundancy confuses following optim...

I'm running the Windows EXE, Oddsock's compiled version of July 13, 2005. I have 1 server running Icecast that generates the streams, and 3 servers that pickup these streams via relay and distribute the streams to our listeners. In other words, I have 3 servers in a cluster that the clients connect to. All three of the cluster servers use the exact same icecast.xml file. The three

Hello folks I'm having trouble playing ogg streams with WinAmp3. I run Icecast2 & Ices2 (both compiled from CVS about two weeks ago) on a Linux box, the files being streamed were encoded with oggenc (from oggutils1.0, managed 80kbitrate...) The problem is that WinAmp3 won't actually play the .ogg stream. When I give it the URL (http://myserver:8000/mount.ogg) it says &...

LLVMers, The 2.2 prerelease is now available for testing: http://llvm.org/prereleases/2.2/ If anyone can help test this release, I ask that you do the following: 1) Build llvm and llvm-gcc (or use a binary). You may build release (default) or debug. You may pick llvm-gcc-4.0, llvm-gcc-4.2, or both. 2) Run 'make check'. 3) In llvm-test, run 'make TEST=nightly report'. 4) When
