TASKING VX-toolset for ARM User GuideC compiler option: --compact-max-sizeMenu entry1. Select C/C++ Compiler » Optimization.2. In the Maximum size for code compaction field, enter the maximum size of a match.Command line syntax--compact-max-size=valueDefault: 200DescriptionThis option is related to the compiler optimization --optimize=+compact (Code compaction or reverseinlining). Code compaction is the opposite of inlining functions: large sequences of code that occur morethan once, are transformed into a function. This reduces code size (possibly at the cost of executionspeed).However, in the process of finding sequences of matching instructions, compile time and compiler memoryusage increase quadratically with the number of instructions considered for code compaction. With thisoption you tell the compiler to limit the number of matching instructions it considers for code compaction.ExampleTo limit the maximum number of instructions in functions that the compiler generates during codecompaction:carm --optimize=+compact --compact-max-size=100 test.cRelated informationC compiler option --optimize=+compact (Optimization: code compaction)C compiler option --max-call-depth (Maximum call depth for code compaction)304
