Linker Options
7-6
7.4 Linker Options
Linker options control linking operations. They can be placed on the command
line or in a command file. Linker options must be preceded by a hyphen (–).
The order in which options are specified is unimportant, except for the – l
(lowercase L) and –i options. Options may be separated from arguments (if
they have them) by an optional space. The following summarize the linker
options:
–a Produce an absolute, executable module. This is the
default; if neither –a nor –r is specified, the linker acts
as if –a were specified.
–ar Produce a relocatable, executable object module.
– b Disable merge of symbolic debugging information.
– c Use linking conventions defined by the ROM autoin-
itialization model of the TMS320C54x C compiler.
– cr Use linking conventions defined by the RAM autoin-
itialization model of the TMS320C54x C compiler.
– e
global_symbol
Define a
global_symbol that specifies the primary
entry point for the output module.
– f fill_value Set the default fill value for holes within output sec-
tions;
fill_value is a 16-bit constant.
– g global_symbol Make a global_symbol static (overrides –h).
– h Make all global symbols static.
–help
–? Display a listing of all available linker command line
options.
– heap size Set heap size (for the dynamic memory allocation in
C) to
size words and define a global symbol that speci-
fies the heap size. The default size is 1K words.
– i
dir
Alter the library-search algorithm to look in
dir before
looking in the default location. This option must
appear before the – l option. The directory or filename
must follow operating system conventions.
–j Disable conditional linking.
–k Ignore alignment flags in input sections.
– l filename Name an archive library file as linker input; filename
is an archive library name. This option must appear af-
ter the –i option. The directory or filename must follow
operating system conventions.
