ARM Compiler armlink User Guide : --autoat, --no_autoat

--autoat, --no_autoat

Controls the automatic assignment of __at sections to execution regions.

__at sections are sections that must be placed at a specific address.


If enabled, the linker automatically selects an execution region for each __at section. If a suitable execution region does not exist, the linker creates a load region and an execution region to contain the __at section.

If disabled, the standard scatter-loading section selection rules apply.


The default is --autoat.


You cannot use __at section placement with position independent execution regions.

If you use __at sections with overlays, you cannot use --autoat to place those sections. You must specify the names of __at sections in a scatter file manually, and specify the --no_autoat option.
