The following functions are recognized during expression evaluation. Their names are case-insensitive.
Given a section-relative offset value, absolute returns the absolute address by adding the address of the containing section to value. It is an error to use absolute outside of a section contents section.
Returns the memory address of the section named section.
Returns the current size of the section name section.
Returns the current position ('.') aligned to a value boundary. This is equivalent to:
(. + expr - 1) & ~(expr -1)
This is generally only used as the start_expression for a section map. It returns the current position (.) aligned such that the section will not span a page boundary of size value. This is equivalent to:
(. % value) + sizeof(this_section) > value ? align(value) : .
Returns the minimum or maximum, respectively, of the two values supplied.
Generates a linker error, displaying string, as well as the current section's name and address, and the current section offset.
Returns 1 if a global symbol exists and is defined, 0 otherwise.
final(finalexpression [,earlyexpression=0])
