3.13 What Kind of Optimization Is Being Performed?

The MSP430 C/C++ compiler uses a variety of optimization techniques to improve the execution speed of your C/C++ programs and to reduce their size.

Following are some of the optimizations performed by the compiler:

Optimization	See
Cost-based register allocation	Section 3.13.1
Alias disambiguation	Section 3.13.1
Branch optimizations and control-flow simplification	Section 3.13.3
Data flow optimizations Copy propagation Common subexpression elimination Redundant assignment elimination	Section 3.13.4
Expression simplification	Section 3.13.5
Inline expansion of functions	Section 3.13.6
Function Symbol Aliasing	Section 3.13.7
Induction variable optimizations and strength reduction	Section 3.13.8
Loop-invariant code motion	Section 3.13.9
Loop rotation	Section 3.13.10
Instruction scheduling	Section 3.13.11

MSP430-Specific Optimization	See
Tail merging	Section 3.13.12
Integer division with constant divisor	Section 3.13.13
