E.1 INTRODUCTION E.2 HIGHLIGHTS MPLAB ® C COMPILER FOR PIC24 MCUs AND dsPIC ® DSCs USER’S GUIDE Appendix E. Deprecated Features The features described below are considered to be obsolete and have been replaced with more advanced functionality. Projects which depend on deprecated features will work properly with versions of the language tools cited. The use of a deprecated feature will result in a warning; programmers are encouraged to revise their projects in order to eliminate any dependancy on deprecated features. Support for these features may be removed entirely in future versions of the language tools. Deprecated features covered are: • Predefined Constants E.3 PREDEFINED CONSTANTS The following preprocessing symbols are defined by the compiler. Symbol Defined with -ansi command-line option? dsPIC30 No __dsPIC30 Yes __dsPIC30__ Yes The ELF-specific version of the compiler defines the following preprocessing symbols. Symbol Defined with -ansi command-line option? dsPIC30ELF No __dsPIC30ELF Yes __dsPIC30ELF__ Yes The COFF-specific version of the compiler defines the following preprocessing symbols. Symbol Defined with -ansi command-line option? dsPIC30COFF No __dsPIC30COFF Yes __dsPIC30COFF__ Yes For the most current information, see Section 3.7 “Predefined Macro Names”. © 2008 Microchip Technology Inc.
