Hi, I run LLVM test suite using the following command and get report.nightly.html successfully. % make report.html TEST=nightly But GCC/LLC, GCC/LLC-BETA and LLC/LLC-BETA columns look strange. Here is for example snippet of "clamscan" test result: [[ Program MultiSource/Applications/ClamAV/clamscan GCC 0.2360 LLC 0.2360 LLC-BETA * GCC/LLC...

Hello, when i used clang for matrix multiplication code with i=j=k=1000351, it successfully generates IR. then i run opt as follows opt -S -O3 -force-vector-width=64 -force-vector-interleave=32 matn.ll -o pimmatnl_64_u32_o3.ll it also worked fine. but when i run llc on the optimized .ll file llc -x86-asm-syntax=intel pimmatnl_64_u32_o3.ll -o matnl-knl4_intel.s i get the following segmentation fault error: #0 0x0000000001826ad8 (llc+0x1826ad8) #1 0x0000000001824aae (llc+0x1824aae) #2 0x0000000001824bfc (llc+0x1824bfc) #3 0x00007fa6bdb52d10 __restore_rt (/lib...

Dear staff, I downloaded an llvm version from the svn trunk at June 12, because the released 2.5 version can not support "gcc -g -Ox", and x=1,2,3. I use the version in svn to compile an httpd.bc file succefully with dbgstoppoint() functions. However, when I use llc to compile the bc file to .s file (llc -f -o httpd.s httpd.bc), I met this error (the httpd.bc file will be attached at the next email): llc: /home/heming/defens/llvm-2.5/lib/CodeGen/AsmPrinter/DwarfDebug.cpp:1235: void llvm::DwarfDebug::ConstructCompileUnit(llvm::GlobalVariable*): Asser...

Can you attach your source code or .ll file? Have you tried a debug build of llc which might give a more readable stack dump or even an assertion message. ~Craig On Fri, Jun 30, 2017 at 10:51 PM, hameeza ahmed via llvm-dev < llvm-dev at lists.llvm.org> wrote: > It happens only when i keep my vector width to >=64, why is that so? > > I have to keep it >=6...

Hi, What is the best way to debug an llc crash using bugpoint?

Hi! In some cases the use of blockaddress() crashes llc. I've attached two test-cases, one that crashes and for reference a slightly modified one (just 2 lines are commented) that works. I compile the files with # llvm-as test_crash.ll -o - | llc -f -o temp.s - and get 0 llc 0x0000000000c6ab6f 1 llc 0x0000000000c6b3...

I am running the following llvm-ld command to produce native code: llvm-ld -native -o code.exe code.bc -lm However, I am getting the following assertion failure in llc. The bytecode has been processed with opt, it passes opt bytecode verification. I'm not too familiar with backend code generation. Does anyone have any insight in to what the problem might be or how to go about debugging it? Regards, Ryan llc: /home/lefever/work/llvm-cvs-070325/includ...
