Thanks everybody for your responses. |

A bit of background: MIPS has 3 ABIs: o32, n32, n64. o32 is the common |
16 |
denominator, but is pretty inefficient. See [1]. As I suspected, all |
17 |
the hardware people care about can use the n32 ABI, which is quite a |
18 |
bit better. |
19 |
|
20 |
To summarize the hardware collection |
21 |
- 5 MIPS III/Loongson little-endian STMicroelectronics systems (Lemote, Gdium) |
22 |
- 11 MIPS IV big-endian SGI systems |
23 |
- 3 MIPS IV little-endian Cobalt systems |
24 |
- 2 MIPS64 selectable-endian Broadcom systems |
25 |
|
26 |
I've got a working n32 big-endian installation, and am preparing an |
27 |
n32 little-endian installation at the moment. Once these are set up, |
28 |
I'll start preparing some n32 stages. |
29 |
|
30 |
I think first priority should be mips4 big-endian. From there, I don't |
31 |
know whether I should build a mips4-le stage for cobalt systems, or a |
32 |
mips3-le stage that would work for cobalt and Loongson. Do we know of |
33 |
any plain MIPS III little-endian hardware? |
34 |
|
35 |
Also, the MIPS port is going to be pretty unmaintainable until we can |
36 |
kill off ~mips from ACCEPT_KEYWORDS. Currently, attempting to upgrade |
37 |
almost anything causes something to break. |
38 |
|

What do you guys think? |

Thanks, |
