I don't know about the SH for sure but the passing of 5-7 byte structures
has been broken on the PA forever and Jeff XFAIL'd strct-stdarg-1.c.
These small structs have been incorrectly padded on the left for
a long time on the 32-bit PA port because there is no way to specify
padding on the right using FUNCTION_ARG_PADDING when the size of
a BLKmode type is wider than a word.

I am trying the following on a hppa64-hp-hpux11 build. These defines
were suggested by Steve Ellcey:

#define FUNCTION_ARG_REG_LITTLE_ENDIAN 1
#define MEMBER_TYPE_FORCES_BLK(FIELD, MODE) 1
#define PAD_VARARGS_DOWN (!AGGREGATE_TYPE_P (type))

strct-stdarg-1.c doesn't fail on the 64-bit port but 20020412-1.c
fails on all PA ports.
