Tables of compiler options. These tables are organized according to area of use
and contain high-level information about the syntax and purpose of each option.
Detailed information about each compiler option in “Detailed Descriptions of the
XL Fortran Compiler Options” on page 90.
Summary of the XL Fortran Compiler Options
The following tables show the compiler options available in the XL Fortran
compiler that you can enter in the configuration file, on the command line, or in
the Fortran source code by using the @PROCESS compiler directive.
You can enter compiler options that start with -q, suboptions, and @PROCESS
directives in either uppercase or lowercase. However, note that if you specify the
-qmixed option, procedure names that you specify for the -qextern option are
case-sensitive.
In general, this document uses the convention of lowercase for -q compiler options
and suboptions and uppercase for @PROCESS directives. However, in the ″Syntax″
sections of this section and in the ″Command-Line Option″ column of the
summary tables, we use uppercase letters in the names of -q options, suboptions,
and @PROCESS directives to represent the minimum abbreviation for the
keyword. For example, valid abbreviations for -qOPTimize are -qopt, -qopti, and
so on.
Understanding the significance of the options you use and knowing the
alternatives available can save you considerable time and effort in making your
programs work correctly and efficiently.
