similar to: [LLVMdev] LLVM 3.4 performance regressed?

Thanks Jonas, I wasn't aware of the gold linker plugin. Here's what I do, in my current workflow. First, I use clang to compile each .c file (e.g. for the bzip2 benchmark, or any other) into a .bc file: specmake clean 2> make.clean.err | tee make.clean.out rm -rf bzip2 bzip2.exe *.o *.fppized.f* find . \( -name \*.o -o -name '*.fppized.f*' \) -print | xargs rm -rf

Hi, I am trying to compare the loop vectorizers effectiveness for different targets relative to each other. That way, I am hoping to find loops that are not vectorized - but could be - on my target by finding other targets doing this successfully. With some luck, there might be something in the Target files that could be fixed with improved vectorization as a result... I would like to do

I am trying to work through the usage of thinlto for distributed builds. Here is the simple thinlto usage, just add -flto=thin everywhere, easy: clang++ -flto=thin -O3 -c -o CreateWay_.o -DSPEC_CPU -DNDEBUG -DSPEC_CPU_LITTLE_ENDIAN -Wno-dangling-else CreateWay_.cpp clang++ -flto=thin -O3 -c -o Places_.o -DSPEC_CPU -DNDEBUG -DSPEC_CPU_LITTLE_ENDIAN

Thanks Teresa Yes it is astar, happen to send a tar of the sources but they are just copies from the spec distribution The ld command is: GNU ld (GNU Binutils) 2.29.1 Thanks for the guidance on path names. The prefix-replace just effects the string written to the object files right? So we could post-process that file with other tools as well, correct? Thanks again --david From: Teresa Johnson

Fails with gold too: Library-native.o:Library.cpp:regway: error: undefined reference to 'vtable for regwayobj' /home/dcallahan/fbsource/fbcode/third-party-buck/platform007/tools/binutils/bin/gold/ld: the vtable symbol may be undefined because the class is missing its key function clang-8: error: linker command failed with exit code 1 (use -v to see invocation) From: Teresa Johnson

Are you saying this is this the first time you've tried to compile it on the cluster? It's easy to determine if g++ is installed and in the PATH - just get a console on the cluster and type "g++". However, AFAIK cluster nodes are not usually configured for software development, are they? Typically you build your code locally and then job it out to the cluster? Greg

I've compiled llvm several times, but this is the first time I saw this error when I was trying to compile it in a cluster. checking tool compatibility... configure: error: g++|clang++|icc required but not found I am pretty sure g++ is installed and in the path. I then downloaded clang++ binary and set path. The error was still there. OS: opensuse 10.1 gcc, g++ version: 4.2.3 Any idea? Bo

Hi all, I wanted to install R under a sunOs machine, so I launched the configuration with the following command: "./configure --prefix /sw/gnu/R/R-2.1.0/sun/ --with-readline=no" The rsult of this configuration seemed good " R is now configured for sparc-sun-solaris2.8 Source directory: . Installation directory: /sw/gnu/R/R-2.1.0/sun/ C compiler:

I am looking for advice on a problem observed with -fprofile-sample-use for samples built with the AutoFDO tool I took the "hmmer" benchmark out of SPEC2006 It is initially compiled clnag++ -o hmmer -O3 -std=gnu89 -DSPEC_CPU -DNDEBUG -fno-strict-aliasing -w -g *.c This baseline binary runs in about 164.2 seconds as reported by "perf stat" We build a sample file from this

The problem was solved by setting environment variable CXX. But somehow a new one came. The gcc is installed in /usr/local/gcc-4.2.3. I managed to change clang/lib/Frontend/InitHeaderSearch.cpp clang/lib/Driver/ToolChains.cpp to force clang use the crt lib for that version. For details, plz see http://www.advogato.org/person/redi/diary/228.html. So now I have no problem of using clang to

Hi, I'ma having some troubles installing R under Unix. As it is written in the "how to install R" the ./configure passed on but when I type make I recieve this error message : gmake[1]: Entering directory `/usr/local/R_HOME/R-2.4.0/m4' gmake[1]: Nothing to be done for `R'. gmake[1]: Leaving directory `/usr/local/R_HOME/R-2.4.0/m4' gmake[1]: Entering directory

I am trying to build iproute2-2.4.7-20010824 from source on a 2.4.24 kernel. I have played a bit with ADDLIB and LDLIBS variables but I always get errors so I suppose it''s best if instead of playing I try to understand what does the following mean (from the README file): ADDLIB should contain inet_* functions, if your libc contains obsolete resolver library (<4.9.4) and you have no

Dear friends, I am trying to install R-2.4.1 from source on Solaris 11 x-86. 64 bits, running on Sun Ultra-20 workstation, and using the SunStudio 11 compilers. I was able to "configure" R correctly, but received an error in "gmake", aparently related to bzip2 which I have been unable to debug. The messages are listed below. The configure.log and configure.status files are

Ok looks like r207606 regressed this. CC'ing Niko. Niko, please see the messages below. This is on openSUSE 13.1 both on i586 and x86-64. Reverting r207606 fixes the second stage bootstrap.

Hi, Recently my libcxx enabled llvm/clang builds has started to fail in stage2. I must admit I am stomped because I cannot make sense of the error: [ 723s] FAILED: /home/abuild/rpmbuild/BUILD/llvm/stage1/bin/clang++ -DLLVMSupport_EXPORTS -DNDEBUG -D_GNU_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -stdlib=libc++ -fPIC -fvisibility-inlines-hidden -Wall -W

Hi all, a user contacted me about a segfault when installing WGCNA package dowloaded from CRAN. I also see a segfault like that on certain installs of R. The package passes all CRAN checks, so presumably this has something to do with the R installation or environment. The R versions here are not the newest but I would guess that this is not an R version issue. I'm attaching two

Dear all, I was willing to use the library "rgl" to plot some 3D graphics, but unfortunately, I wan't able to instal the library. The error message is below. I would be very grateful if you could give me any clues about how I can solve this.

Hi List, I'm trying to build llvm-5.0.0 with clang-3.7.1 on ARM (native building).
