Cross development environment building of a H8/300 ELF target for eCos

I cannot compile eCos with usual GCC. I explain making procedure of GCC which I can compile.

---

Supported Version

tool	Required Version	Using Version
gcc	3.1 or more	3.1.1
binutils	2.12 or more	2.12.1
gdb	5.2 or more	5.2.1

gcc 3.2 does not support it for the time being.

---

building

Option of configure is same as h8300-hms.

binutils

$ tar xzf binutils-2.12.1.tar.gz
$ cd binutils-2.12
$ ./configure --target=h8300-elf
$ make
$ make install

gcc

$ tar xzf gcc-3.1.1.tar.gz
$ cd gcc-3.1
$ patch -p1 < gcc.diff
$ ./configure --target=h8300-elf --enable-languages='c,c++'
$ make
$ make install

I cannot compile it that I do not guess a patch right. Please build g++ with using it by all means.
There is not binary compatible nature with normal gcc. I do not understand what rises when I marged object.

gdb

$ tar xzf gdb-5.2.1.tar.gz
$ cd gcc-5.2
$ patch < gdb.diff
$ ./configure --target=h8300-elf
$ make
$ make install

It is an emulation patch of internal I/O peripheral. Required when testing a sim target.

Please acquire a patch from file release.

---

Using

Same as h8300-hms. However, recompile of a library is necessary because there is incompatibility of object file.

---

Others

An indistinct part please refer to all kinds of h8300-hms association document.
