QCC doen't recognize -m4a option for SH4A code generation

I am trying to compile my application for Renesas SH4A core based platform. How do I instruct the compiler to generate the code for this particular core?

GCC does support -m4a option.

When I use “qcc -Vgcc_ntoshle”, I am not sure if it is generating the code for SH4A core.

Thanks for your help.
