I tried deleting my build directory and restarting from scratch $ cd llvm-project $ mkdir build && cd build $ cmake -G "Unix Makefiles" -DLLVM_ENABLE_PROJECTS=lld ../llvm $ make I got this error: make[2]: *** No rule to make target 'llvm/cmake/modules/GenerateVersionFromVCS.cmake', needed by 'tools/lld/Common/VCSVersion.inc'. Stop. CMakeFiles/Makefile2:57166:

Judging by this path: needed by 'tools/lld/Common/VCSVersion.inc' It looks to me like this is **not** a monorepo layout (if it were, lld would not appear in the tools directory). Therefore the LLVM_ENABLE_PROJECTS=lld is not even doing anything. I don't know how to build without a monorepo these days, and I also don't know what the most recent guidance setting up a monorepo is,

That is slowing down the build visibly, for the speed I should stick with ld at the moment.

Good news, I was able to use up to 37 cores for LLVM build with LLD. The build speed, did not measure precisely though, is comparable to the build with GNU ld case. Thank you all for your help!

Hi Folks, Commit ac1d23ed7de01fb3a18b340536842a419b504d86 introduces a change in the way CodeGen and MC CommandFlags are handled. It's a change that may impact some devs, so I'd better give a small notice here. Basically previous approach was to bundle all options in a .inc file that declares a bunch of llvm::cl options. This file was lying in include/llvm and was to be included in

On another login node which is 256 (GB)/48 (nodes) JURECA at JSC, I never had an LLD issue without setting -j when executing ninja in the past few weeks.

I tried to build lld by following these steps: https://lld.llvm.org/getting_started.html But after 'make install' I can't find lld anywhere and 'make check-lld' results in this message: make: *** No rule to make target 'check-lld'.

Hi LLVM developers, llc -march=mips -debug-only=isel was able to work in Nov 8 2017 https://reviews.llvm.org/D39723 But it doesn't work now: $ clang --version LLVM China clang version 6.0.0 (git at github.com:llvm-mirror/clang.git 9b7b03045ee9b5622028537266aafeb9ea218ac1) (git at github.com:llvm-mirror/llvm.git 3a26601a88394c02603b8756527c55df9ab94d78) (based on LLVM 6.0.0svn) Target:

I got curious how the lld produced gnu hash tables compared to gold. To test that I timed "perf record ninja check-llvm" (just the lit run) in a BUILD_SHARED_LIBS build. The performance was almost identical, so I decided to try sysv versus gnu (both produced by lld). The results are interesting: % grep -v '^#' perf-gnu/perf.report-by-dso-sym | head 38.77% ld-2.24.so

-debug-only only works on builds with assertions enabled. Your version string says optimized build and doesn’t mention assertions.

I tree to compile the LLVM ORC JIT examples. But I'm stuck in some problems I can't solve my own. First at all I compile with C++14 enabled with latest stable LLVM and clang, this means 4.0.1. I get the following error. Do I missed some specific compile option? Compilation looks like this here. |CompilingcontribJIT.cpp PWD:/home/ikuehl/projects-llvm/TurboLisp/domainEngineer

Since I have updated my Linux system, and consequently re-installed R, I am unable to see HTML documentation which I used to access via a web browser. To be more specific, my R installation is declared to be here: > R RHOME /usr/local/lib/R However, if I look at a location such as /usr/local/lib/R/library/base/html this contains only two entries File: 00Index.html File: R.css

Hello, Maybe this is not a bugs. But i fail to install llvm many times and different machine(debian os).

Dear list, (sorry if I post to the wrong place...), Though having spent some time on it, I cannot find an answer by myself to the following behaviour of the read.image function (adimpro package) : I'm running R.2.6.2 on Windows XP. The home directory is C:\Program files\R\R-2.6.2 Version 0.4.4 of adimpro is loaded. ImageMagick 6.3.0 is installed, its directory is C:\Program

Hello one and all. Got a problem with libvirt 6.2.0 and qemu 5.0.0. virsh blockcommit mymachine vda --active --verbose --pivot works until it shows [100%] but it never actually pivots. It just sits there. Is this a known issue with 6.2.0 and i should try 6.3.0? For now i switched back to qemu 4.2.0 and this seems to solve the issue too. Any hints? Ahoi! t.
