2.1.6 --asm
This option instructs the compiler to write a listing to a file of the disassembly of the
machine code generated by the compiler.
Object code is generated when this option is selected. The link step is also performed,
unless the -c option is chosen.
Note
To produce a disassembly of the machine code generated by the compiler, without
generating object code, select -S instead of --asm.
Usage
The action of --asm, and the full name of the disassembly file produced, depends on the
combination of options used:

Compiler option
--asm
--asm -c
Action
Writes a listing to a file of the disassembly of the compiled source.
The link step is also performed, unless the -c option is used.
The disassembly is written to a text file whose name defaults to the
name of the input file with the filename extension .s.
As for --asm, except that the link step is not performed.
