            Bug ID: 100293
           Summary: MinGW-w64 of nvptx offload engine fails
           Product: gcc
           Version: 11.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: brechtsanders at users dot sourceforge.net
  Target Milestone: ---

Created attachment 50691
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=3D50691&action=3Dedit
libatomic/config.log

When doing a Windows native build of the GCC 11.1.0 nvptx offload engine on
Windows using MinGW-w64 and binutils 2.36.1 with:
--target=3Dnvptx-none --enable-as-accelerator-for=3Dx86_64-w64-mingw32
or:
--target=3Dnvptx-none --enable-as-accelerator-for=3Di686-w64-mingw32
the following error is shown:

configure: error: in
`/R/winlibs64_stage/gcc-offload-nvptx-11.1.0/gcc-11.1.0/build_win_offload-n=
vptx/nvptx-none/libatomic':
configure: error: C compiler cannot create executables
See `config.log' for more details

Note that binutils is version 2.36.1 but had patches applied as advises in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D98860 as these were needed to
build the earlier GCC 11 snapshots.=
