Hi, I am a new user to llvm. I have a small question. I am trying to obtain basic block execution frequency for LLVM blocks for mediabench g721 benchmark. I have generated control flow graphs, and instruction mix of the same. however, to obtain runtime profile information, I tried the following. build llvm in PROFILE_ENABLE mode reconfigure path for all the files. run makefile for benchmark g721 : gmake ENABLE_PROFILING=1 According to th...

Hi, I am trying to obtain basic block profiles for mediabench g721 benchmark. I have successfully built llvm in profile_enabling mode. Then so as to find out the block execution frequency, I ran the command, analyze encode.out-cbe. It generated gmon.out which I read using gprof. However, I did not get the basic block level execution frequency. Can anybody help me...

...from the manual. <p>Ok, now the fun stuff. Why Speex support in sweep? sure you can edit files, and even though it's bad to transcode between voice formats, you can at least use sweep to graphically compare files encoded with speex with those encoded in other formats including GSM 6.10, G721/G723 ADPCM and 12/16/24 bit DWVW (those from libsndfile), as well as Vorbis and MPEG. plus, sweep is just cool fun for playing with audio files. There's now a couple of interesting Speex files on sweep's demo page: http://www.metadecks.org/software/sweep/demos.html you might recognise...

Hello. I can't find a gsm plugin for XMMS. How do Unix, Linux, BSD users listen to gsm samples ? Regards...Martin -- While you don't greatly need the outside world, it's still very reassuring to know that it's still there.

Hello, I have written a libsndfile (http://www.mega-nerd.com/libsndfile/) file output plugin for libao. For the moment I haven't done any changes to the core of libao. However some changes could make this more useful. Before I embark on anything like this I'd like to have your opinion on a few things. --- First, what do you prefer ? 1a. Keeping the AU/WAV/RAW plugins and adding

Andy and I briefly discussed this the other day, we have not yet got chance to list a detailed pass order for the pre- and post- IPO scalar optimizations. This is wish-list in our mind: pre-IPO: based on the ordering he propose, get rid of the inlining (or just inline tiny func), get rid of all loop xforms... post-IPO: get rid of inlining, or maybe we still need it, only

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
