ipa

Specifies how to apply interprocedural analysis optimizations.

  #pragma ipa program | file | on | function | off
  
  

See "Interprocedural Analysis" on page 193.

Place this pragma at the beginning of a source file, before any functions or data have been defined. There are three levels of interprocedural analysis:

• program-level: the compiler translates all source files in a program then optimizes object code for the entire program
• file-level: the compiler translates each file and applies this optimization to the file
• function-level: the compiler does not apply interprocedural optimization

The options file and on are equivalent. The options function and off are equivalent.
