Hi Experts,
I am confused on seeing a build snippet working fine:
powerpc-linux-gnu-gcc -T my.lds test.o -o test
As per my understanding, I need to give a -Wl,T option for this to work i.e.
powerpc-linux-gnu-gcc -Wl,-T my.lds test.o -o test
(1) How is this working with -Wl?
(2) This lds creates a section after ro data. I was under the
impression that any lds specified with -T is independent and complete.
But if this lds is declaring just one section, then how does the code
link?
Thanks,
Ajay.

gcc understands the -T flag, and passes it on to ld. Does your script
use INSERT? If it does, then -T does not stop the linker using the
default script. If it doesn't use INSERT, then other sections are
handled as orphans.
