%description
This is the RISC-V fork of the GNU cross-compiler toolchain.  It
includes binutils and GCC.

%setup -q -n %{name}-%{commit}


%build
%configure

# The ordinary Makefile downloads upstream GNU packages.  Instead we
# provide these as local files.  Note this is "DISTDIR" not "DESTDIR".
export DISTDIR=%{_sourcedir}

# Since the Makefile installs as it goes along, set DESTDIR too, and
# clean the buildroot now (instead of at the top of install).
export DESTDIR=$RPM_BUILD_ROOT
rm -rf $RPM_BUILD_ROOT
mkdir -p $RPM_BUILD_ROOT

# We need to use the tools we built as we go along.
export PATH=$RPM_BUILD_ROOT%{_bindir}:$PATH

make

# The 'make linux' rule builds GCC linked against glibc (instead of
# newlib).  However I couldn't make this work, and it's not really
# needed anyway.
#make linux


%install
# Not needed since the make installs as it goes along.
#make install DESTDIR=$RPM_BUILD_ROOT

# Remove some documentation, language files
