It is more efficient to return from the function in the middle of the loop than to exit the loop then return so internal “goto to the return” can be avoided.
|
void function () { uns8 loop; for ( loop = 10; --loop != 0; ) { nop2(); nop2(); } } |
void function () { uns8 loop; for ( loop = 10;; ) { if ( --loop == 0 ) return;
nop2(); nop2(); } } |
The same applies to the return from the function itself.
|
void Function() { if ( condition1 ) { nop(); if ( condition2 ) { nop(); } } } |
void Function() { if ( !condition1 ) return;
nop();
if ( !condition2 ) return;
nop(); } |
