...y. The reason why this seems to occur is that the hybrid scheduler would prefer to suffer a large data-dependency delay over a shorter full-pipeline delay. Do you know why it would do this? (you can see PR11589 for an example if you'd like). Regarding HasReadyFilter: HasReadyFilter just causes isReady() to be used? Is there a reason that this is a compile-time constant? Both Hybrid and ILP have isReady() functions. I can certainly propose a patch to make them command-line options.

What kind of missing symbols are you getting? I had to work around dependencies for a Mingw32 build.

...re-RA instruction schedulers used in LLVM, list-hybrid and list-ilp. I've done some digging on the internet and played around with executing some test files using the two schedules. However, I'm still uncertain of the behaviors and heuristics used in each. For example, the XXXX_ls_rr_sort::isReady for hybrid includes a 3 cycle readydelay (seems arbitrary) whereas the ilp version readies all instructions once data dependencies are resolved. Additionally, the ilp_ls_rr_sort::operator() just calls BURRSort at the end after applying a bunch of heuristics to the queue beforehand. Reading it is q...

I have the git monorepo, and Visual Studio 2015. I am finding that running a build from the command line with msbuild (as a nightly job) invariably fails on the first try, and succeeds on a retry. The first msbuild command looks like this: msbuild ALL_BUILD.vcxproj /p:Configuration="RelWithDebInfo" /m:6 /t:Rebuild This appears to compile everything okay, but invariably fails with

I noticed that some of my event handlers and scripts evaluated in ajax responses didn''t work in Konqueror (3.5.5). document.getElementsByClassName is not defined in these contexts. I can work around this, by saving document.getElementsByClassName in a (namespaced) global variable once and reassigning it before each use. Still, this misfeature is annoying and not restricted to this

I am a student at the University of Alberta under the supervision of José Nelson Amaral, and I have been working on implementing path profiling into LLVM. I have completed my project and would like to submit it. We are looking for a reviewer for the path profiling implementation. We have sent previous requests to the llvmdev list but have so far been unsuccessful. Please see the attached
