HIP separable compilation linking fails when passed archives #2154
Description
Found while working on implementing HIP support in CMake
Tested with compilers provided with ROCm 3.5 and 3.7
Given the following CMake:
cmake_minimum_required(VERSION 3.18)
project(static-lib-rdc HIP)
set(CMAKE_HIP_FLAGS "-fgpu-rdc")
set(CMAKE_HIP_ARCHITECTURES gfx908)
add_library(static-lib file1.cxx file2.hip.cxx file3.hip.cpp file4.hip file5.cu)
add_executable(verify main.cu)
target_link_libraries(verify PUBLIC static-lib)
set_source_files_properties(
file1.cxx file2.hip.cxx file3.hip.cpp file4.hip file5.cu main.cu
PROPERTIES
LANGUAGE "HIP"
)We get the following error when trying to link the verify executable
/opt/rocm/bin/hipcc -fgpu-rdc --amdgpu-target=gfx908 CMakeFiles/verify.dir/main.cu.o -o verify libstatic-lib.a
clang-11: error: no such file or directory: '/tmp/hipcc0wDdnRUU/file1.cxx.o /tmp/hipcc0wDdnRUU/file2.hip.cxx.o /tmp/hipcc0wDdnRUU/file3.hip.cpp.o /tmp/hipcc0wDdnRUU/file4.hip.o /tmp/hipcc0wDdnRUU/file5.cu.o'
It looks something is going wrong and the clang-offload-bundler files are not being placed in the correct location or being removed before linking.
