Compiler Input and Output Options Summary

If no errors occur during processing, you can use the output files from a particular phase as input to a later compiler invocation. The table below describes the options to control the output.

Last Phase Completed	Option	Compiler Input	Compiler Output
compile only	-c	source	Compile to object only (.o), do not link.
compilation, linking, or assembly	-S -o,name -o,name -map	source, assembly, or object files map file	Assigns a name of your choice to an output file
compilation, linking, or assembly	-S[cs]	source	Does not stop compilation after assembly is produced. It controls output into an .s assembly file with code or source annotations containing extra information compared with using -S.
syntax checking	-y	source files preprocessed files	diagnostic list
linking	(default)	source files preprocessed files assembly files object files libraries	executable file, map file
preprocessing	-P, -E, or -Ep	source files	preprocessed files, see Preprocessing

The executable object file is produced when you do not specify any phase-limiting option. You can also request a linker map file. The filename of the first source or object file specified, but absence of the suffix, is the default for the executable object file from the linker.
