8.14 Examples of using placement algorithms for .ANY sections
Using scatter files
These examples show the operation of the placement algorithms for RO-CODE sections in
sections.o.
The input section properties and ordering are shown in the following table:
The scatter file used for the examples is:
LR 0x100
{
ER_1 0x100 0x10
{
.ANY
}
ER_2 0x200 0x10
{
.ANY
}
}
Note
These examples have --any_contingency disabled.
8.14.1 Example for first_fit, next_fit, and best_fit
This example shows the situation where several sections of equal size are assigned to two
regions with one selector. The selectors are equally specific, equivalent to .ANY(+R0) and have
no priority.
