16 bit code for 186 processor

16 bit code for 186 processor

[Pannaga Bhushan]

Dear Sir/Madam,
                          I am using bin utils 2.11.2, which is the latest
available. I wrote a simple hello world program and compiled with gcc using
the -S option to get the .s (assembly file).  I inserted .code16 directive
in the line after the label main:

Then I assembled this with the command   -----    gcc file_name.s

The a.out file that I get from this process gives segmentation fault error
and dumps the core.

What are the steps to get a code that can execute on 186 processor( that is
16 bit processor).

Hope the procedure is simple and also hope that I get a reply soon.

Thanx in advance,
Pannaga Bhushan

I don't know if it is at all possible - anyway, you at least need to build 
all the library you are going to use (including those that come with gcc, 
eg. libgcc, libstdc++, etc.) as 16 bit.
Note that this is just a requirement, I don't think it'll be enough to 
generate 16 bit code at all.
