Thanks for the suggestion. I am using PHDRS command now and it looks
working, although I don't fully understand yet. So I guess if I don't use
PHDRS command and explicitly tell the linker which program headers to
create and which section should be put into which segment, then the linker
will try to create a new program header / segment for my overlay
sections? Why does it do that particularly to overlay sections rather than
picking up an existing one?

Thanks

Tao
