Hi,
FR30 can't build fortran because this is being tripped
in gcc/f/target.h:
/* For now, g77 requires the ability to determine the exact bit pattern
of a float on the target machine. (Hopefully this will be changed
soon). Make sure we can do this. */
#if !defined (REAL_ARITHMETIC) \
&& ((TARGET_FLOAT_FORMAT != HOST_FLOAT_FORMAT) \
|| (FLOAT_WORDS_BIG_ENDIAN != HOST_FLOAT_WORDS_BIG_ENDIAN))
#error "g77 requires ability to access exact FP representation of target
machine
"
#endif
The fr30 appears to only have software floating point based upon
fr30/t-fr30 so I was thinking this had to be easy to fix but
don't know precisely what I am looking for to compare against. :(
Could someone point me in the right direction? Thanks.
