--default_extension=ext
Changes the filename extension for object files from the default extension (.o) to an extension of your choice.
Syntax
--default_extension=ext
Where:
extis the filename extension of your choice.
Default
By default, the filename extension for object files is .o.
Example
The following example creates an object file called test.obj, instead
of test.o:
armcc --default_extension=obj -c test.c
Note
The -o option overrides this. For example,
the following command results in an object file named test.o:filename
armcc --default_extension=obj -o test.o -c test.c
