Chapter 35 Pragmas for Optimization

For more information on the optimization the compiler performs for each optimization level, refer to the Targeting manual for your target platform.

These pragmas correspond to the settings in the Global Optimizations panel. By default, this pragma is disabled.

35.17 optimize_for_size

Controls optimization to reduce the size of object code.

#pragma optimize_for_size on | off | reset

Remarks

This setting lets you choose what the compiler does when it must decide between creating small code or fast code. If you enable this pragma, the compiler creates smaller object code at the expense of speed. It also ignores the inline

directive and generates function calls to call any function declared inline

. If you disable this pragma, the compiler creates faster object code at the expense of size.

The pragma corresponds to the Optimize for Size setting on the Global Optimizations panel.

35.18 optimizewithasm

Controls optimization of assembly language.

Syntax

#pragma optimizewithasm on | off | reset

Remarks

If you enable this pragma, the compiler also optimizes assembly language statements in

C/C++ source code.

This pragma does not correspond to any panel setting. By default, this pragma is disabled.
