Unsolved issues/bugs in the mips/mipsel backend |
---|---|

General |
5 |
------- |
6 |
- [ls][dw][lr] report broken (aligned) BadVAddr |
7 |
- Missing per-CPU instruction decoding, currently all implemented |
8 |
instructions are regarded as valid |
9 |
- Applications running on top of a emulated Linux segfault sometimes |
10 |
when the Qemu FPU emulation is disabled. Also gdb inside the emulated |
11 |
system does not work. Both problems are caused by insufficient |
12 |
handling of self-modifying code. |
13 |
- Floating point exception emulation is incomplete. |
14 |
|
15 |
MIPS64 |
16 |
------ |
17 |
- No 64bit TLB support |
18 |
- 64bit FPU not fully implemented |
19 |
- 64bit mul/div handling broken |
20 |
|
21 |
"Generic" 4Kc system emulation |
22 |
------------------------------ |
23 |
- Doesn't correspond to any real hardware. |
24 |
|
25 |
PICA 61 system emulation |
26 |
------------------------ |
27 |
- No framebuffer support yet. |
28 |
|
29 |
MALTA system emulation |
30 |
---------------------- |
31 |
- We fake firmware support instead of doing the real thing |
32 |
- Real firmware falls over when trying to init RAM, presumably due |
33 |
to lacking system controller emulation. |
