- Subject: sh-elf breakage and fix
It looks like some change broke target sh-elf, and it doesn't build:

only once
../../gcc/gcc/config/sh/sh.c:5946: for each function it appears in.)

make[1]: *** [sh.o] Error 1
It looks like the macro REAL_VALUE_TYPE was moved around, and config/sh/sh.c
can't find it currently.
With the patch, compilation proceeds but crashes when building muldi3.o:

Here is the patch:
