9.4.17 --warn-section-align

Warn if start of section changes due to alignment.

Warn if the address of an output section is changed because of alignment. This means a gap has been introduced into the (normally sequential) allocation of memory.

Typically, an input section will set the alignment. The address will only be changed if it is not explicitly specified; that is, if the SECTIONS command does not specify a start address for the section.
