The RENAME command renames defined and undefined global symbol names.


RENAME pattern AS replacement_pattern [ ,pattern AS replacement_pattern]



is a string, optionally including wildcard characters (either * or ?), that matches zero or more global symbols. If pattern does not match any global symbol, the linker ignores the command. The operand can match both defined and undefined symbols.


is a string, optionally including wildcard characters (either * or ?), to which the symbol is to be renamed. Wild characters must have a corresponding wildcard in pattern. The characters matched by the pattern wildcard are substituted for the replacement_pattern wildcard.

For example, for a symbol named func1:

RENAME f* AS my_f*

renames func1 to my_func1.


You cannot rename a symbol to a global symbol name that already exists, even if the target symbol name is being renamed itself.

You cannot rename a symbol to the same name as another symbol. For example, you cannot do the following:

RENAME foo1 bar
RENAME foo2 bar

Renames only take effect at the end of the link step. Therefore, renaming a symbol does not remove its original name. This means that you cannot do the following:

RENAME func1 func2
RENAME func2 func3

The linker gives an error that func1 cannot be renamed to func2 as a symbol already exists with that name.

Only one wildcard character (either * or ?) is permitted in RENAME.


Given an image containing the symbols func1, func2, and func3, you might have a steering file containing the following commands:

;invalid, func2 already exists EXPORT func1 AS func2

; valid RENAME func3 AS b2
;invalid, func3 still exists because the link step is not yet complete EXPORT func1 AS func3
