similar to: [LLVMdev] source code for llvm

This series of patches address several issues causing memory usage to grow indefinetely on a long lived process. These are not convenional leaks -- memory would have been freed when the LLVM context or/and JIT engine is destroyed -- but for as long as they aren't the memory is usage effectively ubounded. The issues were found using valgrind with '--show-reachable=yes' option: 1.

hello, i want to rewrite clang using c instead of c++,what's your advice and what should i do first,and i want to know where's the source codes of the files which will be read into the buffer to compiler? thank you! -------------- next part -------------- An HTML attachment was scrubbed... URL:

I get the error below (and have for a couple weeks now) when trying to build llvm-gcc on Ubuntu Feisty. In the meantime, on Ubuntu Gutsy, everything has been building fine. Both are release builds for x86. John cc1: StringMap.cpp:177: void llvm::StringMapImpl::RemoveKey(llvm::StringMapEntryBase*): Assertion `V == V2 && "Didn't find key?"' failed.

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

I'm getting the following when building llvm-gcc with an optimized set of LLVM libraries: /ptmp/dag/build.llvm-gcc-4.2.trunk.official.opt/x86_64-unknown-linux-gnu/./gcc/xgcc -B/ptmp/dag/build.llvm-gcc-4.2.trunk.official.opt/x86_64-unknown-linux-gnu/./gcc/ -B/cray/iss/compiler/cost/tools/llvm-tools/llvm/install.trunk.official.opt/x86_64-unknown-linux-gnu/x86_64-unknown-linux-gnu/bin/

Changing a header file somewhere and having to spend 10 minutes waiting for a build leads to a lot of wasted developer time. The real culprit here is tablegen. Can we split support and ADT into two - the parts that tablegen depends on and the parts that it doesn't? >From what I can gather, Tablegen currently depends on these headers and all of their transitive dependencies. #include

It would be better, because a debug tablegen is slower than an optimized tablegen, but it's still slow and it doesn't address the problem that tablegen runs *at all* when it doesn't really need to. I think if tablegen wasn't running all the time we could incremental builds down from 15 minutes (and that's on my really powerful machine) to under 5, which seemed like a big

It's that TableGen depends on Support, so if you change one file in support, support gets recompiled into a new static archive, which triggers a rerun of tablegen on all the tablegen inputs, which is extremely slow.

I thought we already did write tablegen output to temporary files like X86GenAsmWriter1.inc.tmp first and then diffed them with the real .inc file and conditionally copied. ~Craig On Sat, May 27, 2017 at 11:02 AM, David Blaikie via llvm-dev < llvm-dev at lists.llvm.org> wrote: > > > On Fri, May 26, 2017 at 8:06 PM Zachary Turner via llvm-dev < > llvm-dev at

In my experience the buildsystem works fine in combination with tablegen (at least this aspect of it). The real problem here is that tablegen is just slow. Some of the X86 tables take indeed Last time I looked at it tablegen had still room to optimize the way it resolves class hierarchies and the variables within which it did basically one at a time, so it needed to traverse the hierarchies

I am trying to upgrade my code to use the latest version of llvm from svn. Whenever I include "llvm/ADT/HashExtras.h", I get error messages like the following. Does anyone know what is going on? Thanks for any help. llvm[1]: Compiling Aux.cpp for Debug build (PIC) In file included from /home/lefever/work/memrep/src/compiler/include/Aux.h:4, from Aux.cpp:1:

Hi, I'm trying to build llvm (git monorepo) on Ubuntu 18.04 with EXPENSIVE_CHECKS enabled and running into various errors compiling SourceMgr.cpp, depending on which host compiler I use. For example with GCC: $ CC=gcc-8 CXX=g++-8 cmake -GNinja -DCMAKE_BUILD_TYPE=Debug -DLLVM_ENABLE_EXPENSIVE_CHECKS=ON ~/git/llvm-project/llvm/ && ninja ... [89/2690] Building CXX object

Hmm. What about the errors I quoted from using clang-7 (starting about a third of the way down my email, sorry if they got kinda lost in all the noise)? Thanks, Jay.

I just switched gcc from 4.6.2 to 4.7.1 and see the massive amount of warnings, see few examples below. They mostly didn't exist with gcc-4.6.2. rev.159224 Yuri /usr/home/yuri/llvm-2012-06/latest-unpatched/llvm-fix/include/llvm/ADT/PointerUnion.h:56:10: warning: enumeral mismatch in conditional expression:

I just ran into this today. Do we need to update our requirements on libstdc++ version? Jay, did you figure out a way around this?
