Bug ID: 100141
Summary: Unable to build amdgcn-amdhsa offload accelerator for
MinGW-w64 for both Windows 32-bit and 64-bit
Product: gcc
Version: 10.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: brechtsanders at users dot sourceforge.net

amdgcn-amdhsa/libgcc/config.log
When I try to build the GCC amdgcn-amdhsa offload accelerator for MinGW-w64 for
both Windows 32-bit (--target=amdgcn-amdhsa
--enable-as-accelerator-for=i686-w64-mingw32) and 64-bit
(--target=amdgcn-amdhsa --enable-as-accelerator-for=x86_64-w64-mingw32).
This has been the case all versions I tried (last attempt was 10.3.0).
The output I get is:
checking for suffix of object files... configure: error: in
`/R/winlibs64-10.3.0/gcc-offload-amdgcn-10.3.0/gcc-10.3.0/build_win_offload-amdgcn/amdgcn-amdhsa/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See attached amdgcn-amdhsa/libgcc/config.log
The full command line (for Windows 64-bit) looks like this:
../configure
--prefix=/R/winlibs64-10.3.0/inst_gcc-offload-amdgcn-10.3.0/share/gcc
--build=x86_64-w64-mingw32 --host=x86_64-w64-mingw32 --target=amdgcn-amdhsa
--enable-as-accelerator-for=x86_64-w64-mingw32
--with-build-time-tools=/d/Prog/winlibs64-10.3.0/custombuilt/share/amdgcn-tools/amdgcn-amdhsa/bin

I don't think it is a good idea for GCN which isn't supported by binutils to
pass the above options and pretend it is supported by binutils.
As mentioned in
https://gcc.gnu.org/wiki/Offloading#For_AMD_GCN:
do you have LLVM available to do as/ld for GCN?

--- Comment #2 from Brecht Sanders <brechtsanders at users dot sourceforge.net> ---
My plan was to build entirely without LLVM if possible, but if needed to just
build the offload accelerator I do have it available (though I need to check if
I have this target available).
What options are needed to tell configure where to look for the assembler and
linker?
