Unsolved issues/bugs in the mips/mipsel backend
|
|
-----------------------------------------------
|
|
|
|
General
|
|
-------
|
|
- [ls][dw][lr] report broken (aligned) BadVAddr
|
|
- Missing per-CPU instruction decoding, currently all implemented
|
|
instructions are regarded as valid
|
|
- Applications running on top of a emulated Linux segfault sometimes
|
|
when the Qemu FPU emulation is disabled. Also gdb inside the emulated
|
|
system does not work. Both problems are caused by insufficient
|
|
handling of self-modifying code.
|
|
- Floating point exception emulation is incomplete.
|
|
|
|
MIPS64
|
|
------
|
|
- No 64bit TLB support
|
|
- 64bit FPU not fully implemented
|
|
- 64bit mul/div handling broken
|
|
|
|
"Generic" 4Kc system emulation
|
|
------------------------------
|
|
- Doesn't correspond to any real hardware.
|
|
|
|
PICA 61 system emulation
|
|
------------------------
|
|
- No framebuffer support yet.
|
|
|
|
MALTA system emulation
|
|
----------------------
|
|
- We fake firmware support instead of doing the real thing
|
|
- Real firmware falls over when trying to init RAM, presumably due
|
|
to lacking system controller emulation.
