Hi,

I can't go beyond executing a 'Hello World' Plan 9 x86 executable in
Linux, because most executables (I tried 8c and echo) use the MOVBLSX
instruction. Whenever we hit that instruction, the program segfaults.
What does  MOVBLSX do? I looked up the opcode in the executable - 0x10
- which corresponds to ADC (Add with Carry) but I doubt it's that.

Thanks!
