also worth noting: we've been severely limiting ourselves as to the full range |
| 6 |
of possibilities. when we say "ABI", we've largely been focusing on the most |
| 7 |
common aspect. in reality, an ABI is defined by many more features like: |
| 8 |
- endian (little/big) |
| 9 |
- floating point (hard/soft/etc...) |
| 10 |
- ISA selection (mips1/mips2/mips3/mips4/... or i386/i486/i586/i686/... or |
| 11 |
sse1/sse2/mmx/3dnow!/...) |
| 12 |
there are other aspects too, but these are the obvious ones that people are |
| 13 |
selecting every day. people have one toolchain which can generate code for |
| 14 |
all of these things merely by flag selection, not different CHOST values. in |
| 15 |
Gentoo we don't commonly support this as most people don't care, but it has |
| 16 |
been done before. |
