External Interface

This chapter contains reference information for KAI C++.

There are three ways in which you can communicate information to KAI C++: command-line options, keywords, and pragmas.

7.1 Command-line Options

Command-line options fall into roughly four categories.

Compilation Process

These options control the compilation process. For example, -c says to stop once a .o is produced.

Assumptions

These options tell KAI C++ to make some assumption about your program. For example, the abstract float option tells KAI C++ to assume that the program does not "bit-twiddle" floating values.

Requests

These options control which transforms KAI C++ uses. For example, the option --inline_auto_space_time=1.0 requests inlining of some functions not declared inline.

Gang

These options are shorthands for setting a set of options. For example, the gang option +K2 is the same as setting certain other options individually.

The command-line options begin with --, -, or +. Options prefixed by -- are typically long (multi-letter) options. Options prefixed by - are typically short (single-letter) options, however, several exceptions to this rule exist. Options prefixed by + are shorthand abbreviations for a group of other options. There are exceptions to these rules, mostly for the sake of compatibility with options for other C++ compilers.

The command-line options are platform specific. Check the man page for more information.

7.2 Keywords

At this time, the only non-standard keyword recognized by KAI C++ is restrict. This keyword is described in further detail in this discussion of performance.

7.3 Pragmas

At this time, the only pragmas recognized are the tempate instantiation pragmas.
