Hi!
    I am not sure if this is the correct place to report bug with GNU AS. I 
assumed so because GCC internally uses GNU AS (Assembler). Ok the problem is 
that when using Intel syntax, for ARPL instruction the compiler doesnot report 
error when using Scaled Base Index mode when base register is specified as a 16 
bit register (NOT 32 bit). Instead it generates random code and this can cause 
problems during the execution. So ARPL [%ax],%bx compiles and produces: 63 fe
I think it is going to do the same mistakes for all SIB modes. Please check it.
GCC Version: 2.96
Platform: i386-redhat-linux Linux kernel version: 2.4.18-10 intel 686 processor.
Thanks,
Sunil.
