/* We never actually change UNITS_PER_WORD, but defining this causes
libgcc to use some different sizes of types when compiling. */
#define MIN_UNITS_PER_WORD 4
/* When building libgcc, we need to assume 4 words per units even
though UNITS_PER_WORD is 16, because the SPU has basically a 32-bit
instruction set although register size is 128 bits. In particular,
this causes libgcc to contain __divdi3 instead of __divti3 etc.
However, we allow this default to be re-defined on the command
line, so that we can use the LIB2_SIDITI_CONV_FUNCS mechanism
to get (in addition) TImode versions of some routines. */
