Compiler-specific Features
In the following example, section function attribute overrides the #pragma arm section
setting.
#pragma arm section code="foo"
int f2()
{
return 1;
} // into the 'foo' area
__attribute__ ((section ("bar"))) int f3()
{
return 1;
} // into the 'bar' area
int f4()
{
return 1;
} // into the 'foo' area
#pragma arm section

• #pragma arm section [section_sort_list] on page 4-50.
4.3.10 __attribute__((unused))
The unused function attribute prevents the compiler from generating warnings if the
function is not referenced. This does not change the behavior of the unused function
removal process.
Note
This function attribute is a GNU compiler extension that is supported by the ARM
compiler.
Example
static int Function_Attributes_unused_0(int b) __attribute__ ((unused));
4.3.11 __attribute__((used))
This function attribute informs the compiler that a function is to be retained in the
object, even if it is unreferenced.
