Re: [Suggestion] about h8/300 architecture in gcc and binutils

Hello Maintainers,

if you like to drop h8/300 support in linux kernel, thats OK for me.
But i like to see it still supported in gcc & binutils, at least i have some projects and know companies using this architecture in embedded applications, bare metal without OS. These products have lifetime in range of 10...20 years and need toolchain support for software-updates.


Please note for answers: i am only subscribed to binutils mailing list.

Hello Maintainers:

After google search and check the Linux kernel, H8/300 is dead, and for
gcc-4.9.0 and binutils-2.23.2 still has h8300, do we still need it for
another OS ?

Welcome any suggestions or completions, thanks.

The related information in linux kernel next tree:

        Drop support for Renesas H8/300 (h8300) architecture

        H8/300 has been dead for several years, and the kernel for it
        has not compiled for ages. Drop support for it.

The related information in gcc/binutils:

    We can build h8300 cross-compiler for Linux kernel, successfully,
but it has many bugs when building Linux kernel with -Os.
    if we still need h8300 for another OS, is it still valuable to send
these bugs to Bugzilla (although it is found under Linux)?
It is still useful to send code generation bugs for the H8/300 series to
the GCC folks.

OK, thanks, I will wait for 1-2 days which may get another members'
opinions for discussing.

If no additional opinions, I will report them to Bugzilla, and I should
try to continue 'work' with related members (although I am a newbie for
compiler and binutils programming).
