GNU binutils 2.13 or later is recommended with the 64-bit port.
The HP assembler is not supported. It is @emph{highly} recommended
that the GNU linker be used as well. Either binutils must be built
prior to gcc, or a binary distribution of gcc or binutils must be
obtained for the initial builds. When starting with a HP compiler,
it is preferable to use the ANSI compiler as the bundled compiler
only supports traditional C. Bootstrapping with the bundled compiler
is tested infrequently and problems often arise because of the subtle
differences in semantics between traditional and ISO C. There also
have been problems reported with various binary distributions. This
port still is undergoing significant development.
The HP assembler has many limitations and is not recommended. For
example, it does not support weak symbols or alias definitions.
As a result, explicit template instantiations are required when
using C++. Either the HP or GNU linker can be used but it may be
necessary to use the GNU linker when dwarf2 exception support is
implemented.
There are several possible approaches to building the distribution.
Binutils can be built first using the HP tools. Then, the GCC
distribution can be built. The second approach is to build GCC
first using the HP tools, then build binutils, then rebuild GCC.
There have been problems with various binary distributions, so
it is best not to start from a binary distribution.
