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

4 | General |
| 5 | ------- | |
| 2c52c816 TS |
6 | - [ls][dw][lr] report broken (aligned) BadVAddr |
| 7 | - Missing per-CPU instruction decoding, currently all implemented | |
| 8 | instructions are regarded as valid | |
| 509b8ab2 | 9 | - Applications running on top of a emulated Linux segfault sometimes |
| 8b4af705 TS |
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. | |
| 5a5012ec | 13 | - Floating point exception emulation is incomplete. |
| 2c52c816 | 14 | |

15 | MIPS64 |
| 16 | ------ | |
| 17 | - No 64bit TLB support | |
| 5a5012ec | 18 | - 64bit FPU not fully implemented |
| 15dcf5aa | 19 | - 64bit mul/div handling broken |

| 21 | "Generic" 4Kc system emulation | |
| 22 | ------------------------------ | |
| 23 | - Doesn't correspond to any real hardware. | |
| 24 | ||
| 509b8ab2 TS |
25 | PICA 61 system emulation |
| 26 | ------------------------ | |
| 27 | - No framebuffer support yet. | |

29 | MALTA system emulation |
| 30 | ---------------------- | |
| 2c52c816 | 31 | - We fake firmware support instead of doing the real thing |
| 4a109bfb | 32 | - Real firmware falls over when trying to init RAM, presumably due |
| 7246bb21 | 33 | to lacking system controller emulation. |
