Hi I am using SanitizerCoverage feature supported by clang to get the basicblock coverage. my tested binaries are spec cpu2006. I compiled the binary with the option COPTIMIZE = -O0 -fsanitize=address -fsanitize-coverage=bb -flto -fno-strict-aliasing -std=gnu89 -gdwarf-3 After the compiling process is end. I run the 400.perlbench. with the command ASAN_OPTIONS=coverage=1 ./perlbench. However, the AddressSanitizer detec...

Hi If so, is it able to disable this check. All I need is just to get the BB coverage information Regards Muhui Alexander Potapenko <glider at google.com>于2018年9月5日 周三下午6:57写道： > This is a known problem in SPECCPU2006, see > https://github.com/google/sanitizers/wiki/AddressSanitizerFoundBugs > On Wed, Sep 5, 2018 at 7:36 AM Muhui Jiang via llvm-dev > <llvm-dev at lists.llvm.org> wrote: > > > > Hi > > > > I am using SanitizerCoverage feature supported by clang to get the &gt...

Hi all, I would like to compile the benchmarks in the SPEC CPU2006 using different compilers and then see the differences in performance in the code generated by these compilers. One of these compilers is LLVM. So, I'd like to know how to compile and execute the programs in the SPEC CPU2006 using LLVM. I already did it by configuring the SPEC as an external pr...

...issue! This definitely points towards FMA4 encoding in clang's integrated assembler. This fits into the analysis as well - dragonegg *might not* be using integrated assembler at all. Here is a log of my run that ended on happy note using -no-integrated-as.

Can't you just compile the SPEC binaries and use a script in a scripting language of your choice to run them?

Hello, I'm trying to generate bitcode files from the SPEC CPU2006 benchmark suites. First I installed the benchmarks into ~/llvm/projects/test-suite/External/speccpu2006 and then I tried ~/mysandbox/bin/lnt runtest nt --sandbox=sandbox --cc=/Users/asd/llvm/Release/bin/clang --test-suite=/Users/asd/llvm/projects/test-suite --test-externals=/Users/asd/llvm/projec...

Hi, We are using LLVM 2.9 (with the llvm-gcc front end) to compile and run the SPEC CPU2006 benchmarks on x86. We are compiling and running the benchmarks on a an Intel Xeon E5540 processor running Ubuntu 10.10 (64-bit version). For the native x86-64 target, we are using the following command-line arguments: -O3 -march=core2 -mtune=core2 and are getting compile-time errors on the gamess...

Hello, I have built llvm with some added Machine Function Passes and I am trying to use it to build the SPEC CPU2006 benchmarks. I am using llvm test-suite to build the benchmarks. I configured the test-suite with "--with-f2c" but still none of the fortran benchmarks are built or compiled. I tried running simple and nightly tests. Kindly let me know if I am missing some steps and if not then what might...

...something like `clang -emit-llvm hello.c -c -o hello.bc`. I added --enable-jit because I had hope this would make LNT run the JIT tests. I thought this process would cause the creation of bitcode files and then execute them using the LLVM interpreter. I would love to simply run clang but the SPEC CPU2006 benchmarks are quite complicated to build. There already exist makefiles to build them in the LLVM test-suite and I had hope I could use the test-suite to create the bitcode files. It looks like the SPEC makefiles contain rules to build and then run the benchmarks with the interpreter but I could n...

Hi, I am stuck on compiling SPEC benchmark programs. I could successfully compile and run my pass on SPEC CPU2006 C and C++ programs. However, I couldn't compile SPEC CPU2006 FORTRAN programs. Note: I am using the *make *utility to run my pass on SPEC programs. Any idea on how to compile FORTRAN programs using *make *(instead of LNT)?

...r hand, actually the test on our hardware shows disabling this pass without LTO considered, some spec benchmarks would have big regressions, (positive is bad) spec.cpu2000.ref.253_perlbmk 3.27% spec.cpu2000.ref.254_gap 3.18% although I do see some improvements like below, (negative is good) spec.cpu2006.ref.400_perlbench -1.90% spec.cpu2006.ref.471_omnetpp -1.64% spec.cpu2006.ref.482_sphinx3 -1.03% Thanks, -Jiangning 2015-02-26 20:09 GMT+08:00 Renato Golin <renato.golin at linaro.org>: > On 26 February 2015 at 00:57, Ahmed Bougacha <ahmed.bougacha at gmail.com> > wrote: >...

...th Clang as the compiler. I have written a function pass in LLVM and I am trying to run that for SPEC by invoking the pass in the build options of SPEC. The build options of SPEC are in a *.cfg config file, which allows us to specify the choice of compiler while building SPEC. (https://www.spec.org/cpu2006/Docs/install-guide-unix.html) The pass runs for several functions, but llvm crashes at a certain point. I am checking dependencies between various loops in a function in that pass. The crash message and stack dump is: clang-9: /media/kiit/3E9AF7519AF703E5/llvm-project/llvm/lib/Analysis/BasicA...

...given the right options (-O2 -ffast-math for gcc, -O2 -qignerrno for xlc). All of gcc, icc, and xlc produce NaN via the library call with unoptimized code. Choosing 0.0 for Clang/LLVM introduces an unnecessary incompatibility. This is important in practice because of the xalanc benchmark in SPEC CPU2006. This code initializes a variable to a NaN value by assigning it the value sqrt(-2.01) -- don't ask me why. This variable is used to terminate a loop, and when Clang/LLVM produces 0.0 instead of NaN, the loop spins forever. Are there any objections to changing the LLVM optimization behavior...

Hi Tobias- The loop fusion you mention is the one in libquantum/cpu2006 ?

Hi, I want to know what benchmarks can LLVM compile and run successfully. Such as SPEC CPU2000, SPEC CPU2006 or other benchmarks.
