embed memory region information into an elf file

embed memory region information into an elf file

[Massimiliano Cialdi]

The context where I'm surfing is bare-metal, and gcc/binutils toolchain

Is there any magic argument of ld, or some plugin, that allows to
embed the information of memory regions (usually present in the linker
script) into the elf file?

This way I could get the information I need (name, base address and
size) directly from the elf, and I would no longer need to have the
linker script (and parse it).

best regards
Max

In short: "no". :-(

But you can add extra data into ELF files.  For example objcopy has an
--add-section option which could be used to insert a section containing
the required data.  (You would have to decide on the format of the data
and create a file containing the necessary information, but this should
not be too hard).
