This came up when trying to compile the Python bindings against llvm 1.7. File include/llvm/Transforms/Scalar.h declares llvm::createPREPass(), which does not seem to be implemented anywhere. Should I report this in llvmbugs? -- Pertti

Hi Reid, I'll write a separate post about the intrinsics, but just a quick note about the CFLAGS issue.

...the compilation causes unrolling to take place. Am I missing something or should I file a bug? I tried looking around at LoopUnroll.cpp and UnrollLoop.cpp, but did not find an immediate cause for this. From the debug output it looks like instcombine is doing different things in the two cases. -- Pertti -------------- next part -------------- A non-text attachment was scrubbed...

Hi Pertti, The boost Python are not (yet) part of LLVM so I suppose it would make most sense to try to makes fixes/changes so they would work for 1.7 and then try to get them into LLVM CVS. It would be good in such a case to ask the author of the bindings again if he would allow this, because basica...

I have just started to play with callgroups and pickupgroups.. I updates my * from CVS this morning (about 15 mins ago).. I have placed callgroup=1 and pickupgroup=1 into each of my 3 phone configurations in sip.conf.. I place a call from phoneA to phoneB, then I go to phoneC and dial *8# , the call does not get picked up by phoneC and continues to ring on phoneB.. Have I not configured

...for reading and writing memory, then one should be able to use those values and the AliasAnalysis interface to query dependences between MachineInstr's. I am not intimately familiar with how the lowering is done, so if there are some obvious problems with this approach, please let me know. -- Pertti

Hi, I've had a search through the archives and didn't find much. Is anyone using the Monitor application? I have it working but there is a really big drawback. The files are always called the same thing, which means if I make 2 calls one after the other the first recording is lost. I half expected Monitor to use something like ZAP-2-1-<yyyymmddhhmmss>-in/out.wav for it's

...here are a few intrinsics that have to do with libc, like llvm.memcpy and llvm.memmove. However, I would personally prefer less pollution in the intrinsic name space, so I would propose naming the intrinsics with a llvm.libc prefix, e.g. llvm.libc.open and so forth. Any strong opinions on this? -- Pertti

...ink all of libc into one big byte code file, and use llvm-link like this: $ llvm-link hello.bc $NEWLIB/libc.bc -o linked.bc The only concern here is that this brings in all of libc, but I suppose it should be easy enough to run dead code elimination on linked.bc to shake out the unused bits? -- Pertti

The "new features" link at <http://www.llvm.org> appears to point to the release notes of 1.8. Does a similar list exist yet for 1.9, or should I just wait patiently? Thanks, Pertti

...blem manifest itself rather than creating it. Unrolling is absolutely crucial for the application we have. The loops that do not get unrolled are inner loops in a DSP application, and unless we get big fat basic blocks, we don't get much speedup from the VLIW-like machine we are targeting. -- Pertti

...o all, I am involved in a compiler project for Transport Triggered Architectures (think VLIW and you are pretty close), and we are considering using LLVM. Browsing the list archives, I noticed an announcement of Python bindings for LLVM 1.5. Does anyone know the current status of the bindings? -- Pertti
