gcc-3.4.6 and sh-unknown-linux-gnu build error
There was a phenomenon that the multi library was not able to be made when
gcc-3.4.6 was Bilded
with sh-unknown-linux-gnu.
The cause
In config/sh/linux.h,
#if defined (__SH4E__) || defined(__SH4__) ---> Original
#if defined (__SH3E__) || defined(__SH4__) ---> Chenged
It failed in making the multi library becoming.
The influence is still uncertain though there is a similar
description in linux-unwind.h also as for gcc-4.1.2.
It confirms and also when it is bug, it reports.

It is said that the libgcc.a multi-library cannot be made because an impossible register is referred for SH3 if I say easily. It is said that it makes an error of making the multi library in sh-unknown-linux-gnu on the way so that the register definition of 2.4 factions Linux may refer to an impossible combination for this because define is done with SH4E and SH4. Therefore, if this patch is put away without recapitulating as -- target=sh-unknown-linux-gnu, it is sure to become an error. The header file was made here based on crosstools 0.84, and it succeeded in making of all libraries since it had it of seeing the header file. It ..said extent alone.. is not thought that the SH architecture can be basic in my understanding big endian and set little endian to the end. Endian is not seen on the linux side but the SH3 architecture or the SH4 architecture is not passed though the register for SH4 is referred when the header file on the linux side sees the register of SH4 ..seeing... At least, only refer to SH4E SH4 when you see the register added with SH4 on the linux side.

Perhaps you can >help Motohisa, both with the compiler and the language barrier? Sorry. I am not good at English. I do not think that it is correct to detach SH3E. I transplanted linux to TMM-1000 and TMM-1200. I am wishing that all of SH2,SH2E, SH3, SH3E, SH4, and SH4E can be compiled with sh-unknown-linux-gnu-gcc. Sorry Mr. Kojima.
