[linuxsh-dev] GNU CVS gcc -- fixup for -m4-nofpu

[Bryan R. <br...@ix...>]

Hello,

For anybody else as crazy (stupid?) as me that wants to try sh4 GNU CVS
gcc, here's a patch to fix some compiler-defined symbols when -m4-nofpu
is used. Currently, __sh3__ is defined by -m4-nofpu, but __sh4__ is not,
which is causing the kernel compile to fail. Here's my fixup patch for
gcc (for -rgcc-3_0-branch):

is anyone else using a cvs version of gcc with good results?

Also, is anyone using a new glibc (2.2, 2.2.1, 2.2.2) with the old
(LinuxSH CVS) binutils and gcc? I've tried to do so, but get lots of
undefined symbols and some conflicts with libgcc when trying to link
(staticly or dynamically). but glibc itself builds without any error.

Regards,

Bryan
