Output control

The options in this category control the type of file output the compiler produces, as well as the locations of the output. These are the basic options that determine the compiler components that will be invoked; the preprocessing, compilation, and linking steps that will (or will not) be taken; and the kind of output to be generated.

Table 1. Compiler output options
Option name	Equivalent pragma name	Description
-c	None.	Prevents the completed object from being sent to the linker. With this option, the output is a .o file for each source file.
-C, -C!	None.	When used in conjunction with the -E or -P options, preserves or removes comments in preprocessed output.
-E	None.	Preprocesses the source files named in the compiler invocation, without compiling, and writes the output to the standard output.
-G	None.	Generates a shared object enabled for runtime linking.
-qmakedep, -M	None.	Creates an output file containing targets suitable for inclusion in a description file for the make command.
-MF	None.	Specifies the target for the output generated by the -qmakedep or -M options.
-qmkshrobj	None.	Creates a shared object from generated object files.
-o	None.	Specifies a name for the output object, assembler, or executable file.
-P	None.	Preprocesses the source files named in the compiler invocation, without compiling, and creates an output preprocessed file for each input file.
-S	None.	Generates an assembler language file for each source file.
-qshowmacros	None.	Emits macro definitions to preprocessed output.
-qtimestamps	None.	Controls whether or not implicit time stamps are inserted into an object file.
