I put some functions of my program into a separate text section called .cryptext and I want to have this section start at a fixed address. To achieve that I should probably be using gcc -Wl,--section-start=.cryptext=0x12345678
That works all right as long as .cryptext is only defined in a single object file. When there are functions in multiple object files placed in .cryptext then without -Wl,--section-start all the .cryptext sections are merged into a single one in the final binary, that's what I want. However with -Wl,--section-start created .cryptext, .cryptext.1, .cryptext.2, etc and only the first one is placed at the specified address.
The problem isn't --section-start . The problem is that .cryptext is an orphan section, i.e. one not mentioned in the linker script. For whatever reason, the linker does that with orphan sections. So far as I know, the only documentation on the subject is in bugzilla somewhere.
