[linuxsh-dev] A patch for gcc 3.3

[kaz K. <kk...@rr...>]

Hi!

I put a patch against mainline gcc (CVS, version 3.3 20020831),
which enables the DWARF2 exception for SH-3/4 and the better
support for c++ and java:

As usual, it is an experimental one. Don't use it for your real
work and please forget it when it doesn't work for you :-)
I've tested it only for the little endian SH-4.

BTW, the compiler part was sent to the gcc mailing list already,
but too late to add new features to 3.3. Tiny changes for libffi
and libjava are not yet sent, since they are meaningless until
the compiler part is approved.

Note:
This patch slightly depends on the kernel version. It assumes
2.4.18 with Jeremy's siginfo fix. For another kernels, you have
to rewrite MD_FALLBACK_FRAME_STATE_FOR in gcc/config/sh/linux.h.
I'm adding CXXFLAGS='-g -O' when building to avoid a few unresolved
problems of the current gcc 3.3 for SH.
