Specifying Assembly Files

You can use the -Sfile option to generate an assembly file and specify an alternate name for this assembly file .

IA-32 compiler:

prompt>ifc -Sfile.asm x.f90

Itanium compiler:

prompt>efc -Sfile.s x.f90

In the above example, -S tells the compiler to generate an assembly file and assign to it the name file.asm / file.s rather than the default x..

If the file name is not specified, the option -S tells compiler to:

• generate an assembly file of the source file

• use the name of the source file as a default assembly output file name

• place this file in the current directory.

Note

The -S option does not stop the compiler upon generating and saving the assembly files. Without the -S option, the compiler proceeds to generating object files without saving the assembly files.

Producing Assembly Files with Annotations and Comments

Options -fcode-asm and  -fsource-asm produce annotations in assembly files as follows:

• -fcode-asm and inserts code byte information in the assembly file

• -fsource-asm and inserts high-level source code in the assembly file

In addition, the options -fverbose-asm and  -fnoverbose-asm enable and disable, respectively, inserting comments containing compiler version and options used in the assembly file.
