It did partially fix the issue but there is still one problem: llvm-objdump -sx gives: Version References: required from libpthread.so.0: 0x09691a75 0x00 05 GLIBC_2.2.5 0x09691972 0x00 09 GLIBC_2.3.2 0x09691973 0x00 07 GLIBC_2.3.3 0x06969192 0x00 12 GLIBC_2.12 required from libdl.so.2: 0x09691a75 0x00 21 GLIBC_2.2.5 required from libuuid.so.1: 0x09da27b0 0x00 19

Thank you very much for your help Fāng-ruì Sòng. I've tried various things like linking directly to libm-2.32 but it didn't work, it seems that libm-2.32 still pulls libmvec. I have the following linker flags: CLANG_LDFLAGS="-fuse-ld=lld -static-libstdc++ -static-libgcc -fvisibility=hidden -fdata-sections -ffunction-sections" CLANG_LDFLAGS="$CLANG_LDFLAGS

No. A shared object is needed if it is linked in (1)--no-as-needed mode or (2) after --gc-sections, a symbol referenced by a live input section is defined by the shared object. You'll need to check whether a symbol is defined by libmvec.so.1 On Mon, Nov 9, 2020 at 9:57 AM Alexandre Bique <bique.alexandre at gmail.com> wrote: > > On Mon, Nov 9, 2020 at 6:52 PM Fāng-ruì Sòng

Hi Pavel, thank you for you response. objdump -T showed that there are no symbols defined in liblldb.so. After few compilations I found that problem is with linking with LLD (-DLLVM_ENABLE_LLD=ON) without the directive everything is ok.

Martin, Well, thanks for jumping in! We need all the help we can get ;) I changed the execute bit as you suggested and recompiled, no luck, still the same error message. Below is the output you wanted me to look at, its a bit beyond me so I include both a brief grep summary and then the whole enchilada. I do note that my output is different from yours, but I'm not sure how to interpret. I

Rafael, here is a repro.tar to look at: https://reviews.llvm.org/F3100177 The attached foo.diff adds a print which shows the issue. ``` NAME: sleep SYMINDEX: 2 NAME: sched_yield SYMINDEX: 1 NAME: __libc_start_main SYMINDEX: 0 ``` `readelf --relocs` Shows that we create : ... 000000255110 002900000007 R_X86_64_JUMP_SLO 0000000000254410 __xstat at GLIBC_2.2.5 + 0 000000255118 001e00000007

It seems that fast-isel for intel does not handle strlen. It's a general problem in fast-isel . ~/llvmw/build/Deb~/llvmw/build/Debug+Asserts/bin/clang -O0 -mllvm -fast-isel-verbose -mllvm -fast-isel strlen1.c strlen1.c:12:3: warning: implicitly declaring library function 'printf' with type 'int (const char *, ...)' printf("%i\n", len); ^
