C6.10 Aligning execution regions and input sections
There are situations when you want to align code and data sections. How you deal with them depends on whether you have access to the source code.
Aligning when it is convenient for you to modify the source and
recompile
When it is convenient for you to modify the
original source code, you can align at compile time with the __align(n) keyword, for example.
Aligning when it is not convenient for you to modify the source and
recompile
It might not be convenient for you to modify the source code for
various reasons. For example, your build process might link the same object file into
several images with different alignment requirements.
When it is not convenient for you to modify the source code, then you
must use the following alignment specifiers in a scatter file:
ALIGNALL
Increases the section alignment of all the sections in an execution region, for
example:
ER_DATA … ALIGNALL 8
{
… ;selectors
}
OVERALIGN
Increases the alignment of a specific section, for example:
