This is bad because r1 is clobbered by PLT. +The another functions listed in the standard libgcc-std.ver which +possively have similar problem are __ashlsi3, __ashrsi3 and __lshrsi3, +though these are used only by SH1/2. +The patch below simply uses an SH specific libgcc-std.ver which drops +these functions. SH linux uses a linker script libgcc_s.so having +libgcc.a as a suppementary library, so these functions given by +libgcc.a when needed in the link time. +Although mainline has one failure in bulding zlib which can be avoided +with -fno-reorder-blocks for sh3-unknown-linux-gnu target, x86 cross +to sh3-unknown-linux-gnu can be build successfully on mainline with +this patch except the above failure. 3.4-branch successfully bootstraps +with it and there are no new failures on the native sh4-unknown-linux-gnu. +The patch is highly sh-linux specific and seems to be safe. I'll check +it into mainline. +The original PR is also for sh3 netbsd. I'd like to leave it for the +netbsd experts. + +I think that it's too late for 3.3.4.
