| 31 | * Each unique machine architecture needs an entry in this file | |
| 32 | * So far the differences boil down to: endianness, 32 vs 64 bit pointers, | |
| 33 | * and on 32bit ones, whether double is aligned to one word or two words. | |
| 34 | * Those result in the 6 formats listed below. | |
| 35 | * | |
| 36 | * If any of the assertion errors in fccache.c fail, you need to add a new | |
| 37 | * architecture. Contact the fontconfig mailing list in that case. | |
