Chapter 11. Directives

This chapter provides an alphabetical reference to the compiler directives and includes background information on:

• The XLF directives used for SMP programming. To ensure these directives are recognized by the compiler, compile your code using either the xlf_r or xlf90_r invocation commands and specify the -qsmp compiler option. Note that some directives are recognized by the compiler if either the -qsmp or -qhot compiler option is specified.

• The XLF directives used to specify threadsafe code. To ensure this functionality is recognized by the compiler, compile your code using either the xlf_r or xlf90_r invocation commands.

• All comment form and noncomment form XLF directives from XL Fortran Version 4.1.
