5 IAR Pragmas

This section shows a summary of IAR pragmas and the best MPLAB XC32 replacement where that is available. These pragmas and their MPLAB XC32 equivalents are discussed in more detail in the sections that follow. It is recommended that you compare the relevant sections in the MPLAB® XC32 C/C++ Compiler User's Guide with those in your IAR C/C++ Compiler User Guide to ensure that migrated code will work as expected in all situations.
