I can-t build the m68k-elf toolchain - it gets an error trying to build
libgloss.
Hence, I don't have stdio.h.
Could you attach a preprocessed testcase?

bootstrap / regtest on i686-pc-linux-gnu and

show no regressions. Can't regtest for m68k, though.

Is SH big-endian? The patch looks good but we need to test it on a big-endian
platform. I can give it a try on PowerPC if that can help.

Yes, the default for sh-elf - which is what I have tested - is big endian.

The patch is OK but let's beef up the comment a little bit:

+ {
+ if (!MODES_OK_FOR_MOVE2ADD (mode, reg_mode[regno]))
+ return false;
+ /* For big endian, the starting regno for the subreg might be

/* The value loaded into regno in reg_mode[regno] is also valid in
mode after truncation only if (REG:mode regno) is the lowpart of
(REG:reg_mode[regno] regno). Now, for big endian, the starting
regno of the lowpart might be different. */
+ int s_off = subreg_lowpart_offset (mode, reg_mode[regno]);
+ s_off = subreg_regno_offset (regno, reg_mode[regno], s_off, mode);
+ if (s_off != 0)
+ /* We could in principle adjust regno, check reg_mode[regno] to be
+ BLKmode, and return s_off to the caller (vs. -1 for failure),
+ but we currently have no callers that could make use of this
+ information. */
