When a listing file is generated using the -qsource option, -qskipsrc can be used to determine whether the source statements skipped by the compiler are shown in the source section of the listing file. Alternatively, the -qskipsrc=hide option is used to hide the source statements skipped by the compiler.
In general, the -qskipsrc option does not control whether the source section is included in the listing file, it only does so when the -qsource option is in effect.
To display all source statements in the listing (default option):
xlc myprogram.c -qsource -qskipsrc=show
To omit source statements skipped by the compiler:
xlc myprogram.c -qsource -qskipsrc=hide
None.
