+@heading nvptx-*-none
+Nvidia PTX target.
+
+Instead of GNU binutils, you will need to install
+@uref{https://github.com/MentorEmbedded/nvptx-tools/,,nvptx-tools}.
+Tell GCC where to find it:
+@option{--with-build-time-tools=[install-nvptx-tools]/nvptx-none/bin}.
+
+A nvptx port of newlib is available at
+@uref{https://github.com/MentorEmbedded/nvptx-newlib/,,nvptx-newlib}.
+It can be automatically built together with GCC@. For this, add a
+symbolic link to nvptx-newlib's @file{newlib} directory to the
+directory containing the GCC sources.
+
+Use the @option{--disable-sjlj-exceptions} and
+@option{--enable-newlib-io-long-long} options when configuring.
