illegal hardware instruction during MIPS-I ELF linux user emulation

[Libo Zhou]

Hi all,

I have an binary file generated by a cross compiler. The 'file' command says

$ file test
test: ELF 32-bit LSB LSB executable, MIPS, MIPS-I version 1 (SYSV), statically 
linked, with debug_info, not stripped.

When I executed it with

$./qemu-mipsel test
qemu: uncaught target signal 4 (Illegal instruction) - core dumped
[1] 11088 illegal hardware instruction (core dumped) ./qemu-mipsel test

However, when I use another cross compiler that generates MIPS32 rel2 binaries, 
it worked fine.

Can anyone tell me what's going wrong?

Cheers,
Libo Zhou
