In SmallVector.h: class SmallVectorBase { *protected:* void *BeginX, *EndX, *CapacityX; *protected:* SmallVectorBase(void *FirstEl, size_t Size) : BeginX(FirstEl), EndX(FirstEl), CapacityX((char*)FirstEl+Size) {} In StringMap.h: class StringMapImpl { *protected:* // Array of NumBuckets pointers to entries, null pointers are holes. // TheTable[NumBuckets] contains a sentinel value

From: José Fonseca <jfonseca at vmware.com> When the hash function uses object pointers all free entries eventually become tombstones as they are used at least once, regardless of the size. DenseMap cannot function with zero empty keys, so it double size to get get ridof the tombstones. However DenseMap never shrinks automatically unless it is cleared, so the net result is that certain

Thanks, I tried calling ResetAllOptionOccurrences after the run like this… // Compile the module TimeCompilations times to give better compile time // metrics. for (unsigned I = TimeCompilations; I; --I) if (int RetVal = compileModule(argv, Context)) return RetVal; if (YamlFile) YamlFile->keep(); cl::ResetAllOptionOccurrences(); return 0; } Unfortunately

Good morning Jose, Thank you to send patches. - Please send patches to llvm-commits. - Please make patches with "--attach". You may add "format.attach" to git config. I have not seen yours yet, but I pushed yours to github; https://github.com/chapuni/LLVM/compare/ed4edf9e...jfonseca%2F20110316 (Excuse me I could not input accent) ...Takumi On Wed, Mar 16, 2011 at 8:15

Hello everyone! I'm a newcomer for the great LLVM project. I've started to explore the source code of LLVM project to become more familiar with it, and I've found some strange usage of move semantics in constructor of StringMapImpl( StringMapImpl &&RHS) {...} class in include/llvm/ADT/StringMap.h line 56. Could anyone explain me the purpose of zeroing of all fields of RHS in

Hi llvm-dev, Our code base has a ancient copy of llvm (ver 3.5.1), and it uses the LLVM code gen for some domain-specific language. The previous dev left a global lock around the usage of LLVM code gen stating that because LLVM code gen can only be accessed single-threaded it needs to be protected with this global lock. But now this lock has caused some perf issues as we pretty much lose

Thank you Johannes, I looked it up and it seems that we're creating one LLVMContext per compilation "unit", not sure if that matters. i.e. there's no single globally shared LLVMContext object. Is LLVMContext *the* concurrency isolation (or unit) here? On Wed, Apr 3, 2019 at 6:34 PM Doerfert, Johannes <jdoerfert at anl.gov> wrote: > Do you use one llvm context or one

Hi all, I have a compilation failure with 'insert' member function of SmallPtrSetImpl class because the return value is changed from r222334. But the comment of the function is same with before as follows: /// insert - This returns true if the pointer was new to the set, false if it /// was already in the set. std::pair<iterator, bool> insert(PtrType Ptr) { auto p

I''m running into a situation where I can''t unmount a mounted snapshot. It shows "busy" even though neither lsof nor fuser show any open files. Umount -f doesn''t work although umount -l does. Is there anything else I can do to debug this scenario or to clear the busy status myself? Or am I down to rebooting each time? This is on stock ubuntu-10.04, x86.

While building a package, I see the following: * checking R code for possible problems ...

Does LLVM try and make sure that all memory is freed before compiler exit? For example, It seems like the ARM constant pool code that I'm reading will leave a lot of un-deallocated memory. Maybe I'm missing something here. Reed

I'm trying to link a program with LLVM on Linux. I've managed to take out the test files from 'llvm-config --libs' but now it's getting errors with missing symbols. The same program successfully links with the same version of LLVM (3.8) on Windows, so it's not a problem with the code per se, it's some kind of configuration issue. Any ideas? g++ -std=c++11
