The other difference is the word order for doubles (and extended precision doubles -- but I do not think ghc uses those). The nokia 770 is a little-endian system -- but in, ghc/rts/StgPrimFloat.c, I had to hack this #ifdef:
#ifdef WORDS_BIGENDIAN #define L 1 #define H 0 #else #define L 0 #define H 1 #endif
nice find!
Should we define a new variable, such as DOUBLES_WORD_ORDER? Or just hack the existing #defines to something like,
#ifdef WORDS_BIGENDIAN || NWFPE
I think the first option is better, because then people do not have to know about architecture specific hacks.
The right way to fix this is to add an autoconf test, second best is to change the #define as you did above. If you can hack up an autoconf test and send a patch, we'll commit it. Cheers, Simon
