Re: Linkerscript


Hi jeroen,

I have a question about the linkerscript automatically generated by eCos.

For which particular target ?


On a
couple of lines the expression ". = .;" is used. What is de meaning of this?
What does it do?

Nothing - it is a null operation.


Example:
    .vectors 0x00400000 : { . = .; KEEP(*(.vectors)) } > ram

The source for this particular linker script appears to be eCos specific, since I did not find it in the binutils repository. My guess would be that in the original source there is an extra expression which can be conditionally included as part of this assignment. eg something like:


.vectors 0x00400000 : { . = . $(VECTOR_OFFSET);

where VECTOR_OFFSET might be defined as "" under some circumstances and as say "+ 0x1000" under other circumstances. (I am just guessing here).

Cheers
  Nick
