if you have time, o32 & n32 support needs to be reworked.
We have two binaries qemu-mips and qemu-mipsn32 sharing the same ELF
mask/magic.
As n32 identifies a kernel ABI version, we should have only one binary
for qemu-mips and qemu-mipsn32 and the ABI version should be identified
at runtime as it is done for ARM:
ce4defa062 Arm Linux EABI syscall support.
[I think we can use e_flags for that]
I never did the change because I don't know where to find mipsn32
binaries to test my changes.
Thanks,
Laurent
