Is there any particular reason that CaptureTracking.h isn't folded into ValueTracking.h? I was looking for the method to check whether a pointer would be captured and looked in ValueTracking.h, unaware that a new header had been created for that one method. Would anyone mind if I folded CaptureTracking into ValueTracking? Nick -------------- next part -------------- An HTML attachment was

...cement of non-escaping allocations. It rewrites uses of the allocation and needs to know about "aliases" as their uses also need to be rewritten. Currently it knows about all the "aliases" supported by CT, but it's not resilient to further changes in CT. Proposal Currently CaptureTracker is notified about capturing uses through CaptureTracker::captured. I propose to notify the tracker about all the uses explicitly specifying the kind (NoCapture, Alias, Capture). This way the tracker can only accept Alias uses it knows how to handle. If something unexpected comes up the tracker can...

If there are any students looking for ideas, here a couple of projects you might consider. p.s. Anyone know where in the repo the OpenProjects page is? I'd expected it to be the docs/ folder of the LLVM repo, but it wasn't. Transactional Memory Optimization Intel recently introduced transactional memory support in hardware. This project would consist of implementing optimizations

PR43308 describes a case where StackProtector fails to protect against a fairly simple smash. This problem started after r363169, which removed StackProtector's own analysis function HasAddressTaken, and used CaptureTracking's PointerMayBeCaptured instead. The problem here is that "pointer is captured" and "pointer could be used to smash the stack" are not equivalent

Hi there lowering experts, Can the llvm.mem* intrinsics ever turn into a library call? Or do they invariably turn into inline code? This comes up because there was a patch to StackProtector to use CaptureTracking instead of a home-grown analysis, which changes the treatment of calls to intrinsics. (The old code treated them as normal calls, the new code decides intrinsics can never capture.)

Hello! I am trying to retrieve all instructions from a function's body that are dependent on a specific argument. The strategy I am currently using for that is to follow all uses of the argument and record them. Also, whenever I encounter a store of a dependent value, I try to find loads in the function that are dependent on that store and resume use-tracking from there. For this purpose I am

OK thanks for the replies. Yes, I was planning to use a garbage collector. This is for a functional language, so there's no real way to determine when memory needs to be freed without one. > Firstly, the pointer has to not make it into any function call at all, since any function might in turn call free(). Then we need to do escape analysis as you pointed out, but that's not

Sorry for the rapid fire replies, but this configuration works for me: install(DIRECTORY include/ DESTINATION include # FILES_MATCHING PATTERN "*.def" PATTERN "*.h" PATTERN "*.td" PATTERN "*.inc" PATTERN ".svn" EXCLUDE ) install(DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/include/ DESTINATION include # FILES_MATCHING PATTERN

Hi, I might just be doing something stupid, but when I do $ cmake -DCMAKE_INSTALL_PREFIX=/usr/local/llvm-2.8 -DCMAKE_BUILD_TYPE=Release .. $ sudo make install I don't get the expected headers in /usr/local/llvm-2.8/include/llvm It is simply an empty directory. What am I doing wrong? This is on Mac OS X, CMake 2.8+ Kind regards, Samuel
