I can see a rodata.str1.4 section in one of the
programs compiled with gcc for my Atmel AT91M40800
(ARM7TDMI core) board. It's NOT a c++ project and it
doesn't explictly declare any constans; rodata.str1.4
contains all the strings in the source. I have no idea
why it's called like that, but the conclusion is
clear: .rodata is not the only section that can hold
readonly data, so that syntax is not redundant; on the
contrary, it's a very good thing to use it (unless you
don't want to start wondering where your strings are,
which is what I did the first time I compiled my
program and used only *(.rodata) in my linker command
file).
