Assemblers and Linker

The assemblers and linker you can use are summarized in this table:

You can specify alternate tool locations and options for preprocessing, compilation, assembly, and linking.

Assemblers

For 32-bit applications, Linux supplies its own assembler, as.

For Itanium-based applications, use the Itanium assembler, ias.  The following example compiles a Fortran file to an assembly language file, which you can modify as desired. The assembler is then used to create an object file.

1. Issue a command using the -S option to generate an assembly code file, file.s: ifort -S -c file.f

2. To assemble the file.s file, call the Itanium® assembler with this command: ias -Nso -p32 -o file.o file.s

In the above command line, the following assembler options are used:

-Nso suppresses the sign-on message.

-p32 enables defining 32-bit elements as relocatable data elements. (This option is available for backward compatibility.)

-o file.o indicates the output object filename.

Linker

The compiler calls the system linker, ld(1), to produce an executable file from the object files.
