LLVM with AMD backend fails to link binary object #6089
Description
Describe the bug
LLVM compiler with AMD backend cannot link finally binary
To Reproduce
Please describe the steps to reproduce the behavior:
-
Include code snippet as short as possible: N/A
-
Specify the command which should be used to compile the program:
The final clang++ command for linking the binary that caused the failure was this:
/home/jaytong/sycl_workspace/llvm/build/bin/clang++ -v -O3 -fsycl -fsycl-targets=amdgcn-amd-amdhsa -Xsycl-target-backend --offload-arch=gfx908 -Wall -Wno-unknown-pragmas -Wextra -stdlib=libstdc++ -fcolor-diagnostics -Qunused-arguments -O2 -g -DNDEBUG CMakeFiles/ethminer.dir/main.cpp.o -o ethminer -L/home/jaytong/DPA_Projects/LIBS/json/1.9.5/lib/cmake/jsoncpp/../../../lib -Wl,-rpath,/home/jaytong/DPA_Projects/LIBS/json/1.9.5/lib/cmake/jsoncpp/../../../lib:/home/jaytong/DPA_Projects/LIBS/boost/1.73.0/lib:/home/jaytong/DPA_Projects/LIBS/openssl/1.1.1f/lib: ../libethcore/libethcore.a ../libpoolprotocols/libpoolprotocols.a ../libdevcore/libdevcore.a libethminer-buildinfo.a /home/jaytong/DPA_Projects/LIBS/boost/1.73.0/lib/libboost_system.so.1.71.0 /home/jaytong/DPA_Projects/LIBS/boost/1.73.0/lib/libboost_thread.so.1.71.0 ../libapicore/libapicore.a -ljsoncpp /home/jaytong/DPA_Projects/LIBS/openssl/1.1.1f/lib/libssl.so /home/jaytong/DPA_Projects/LIBS/openssl/1.1.1f/lib/libcrypto.so ../libethcore/libethcore.a ../libethash-sycl/libethash-sycl.a ../libethcore/libethcore.a ../libethash-sycl/libethash-sycl.a /home/jaytong/DPA_Projects/LIBS/ethash/0.4.3/lib/libethash.a ../libhwmon/libhwmon.a -ldl ../libdevcore/libdevcore.a /home/jaytong/DPA_Projects/LIBS/boost/1.73.0/lib/libboost_system.so.1.71.0 -lpthread libethminer-buildinfo.a /home/jaytong/DPA_Projects/LIBS/boost/1.73.0/lib/libboost_filesystem.so.1.71.0
After specifying the -v in the clang++ command, the llvm-foreach reported an error after trying to do the following:
