RES: [avr-gcc-list] float type

[Eric Pasquier]

You have to compile with no optimization: -O0

The compiler is wiping your code away because your variable x is not used anywhere else.

Assunto: [avr-gcc-list] float type

Hi,

 

 

I want to use float type in my code, but after i compile it, the avr-gcc not the generate code for the variable:

 

....

 float x = 1.23;
 x = x*2;

 sei();
....

 

 320:Freq.c        ****  float x = 1.23;
 321:Freq.c        ****  x = x*2;
 322:Freq.c        ****   
 323:Freq.c        ****  sei();
 614                .LM76:
 615                /* #APP */
 616 0258 7894        sei
 617                /* #NOAPP */
 618                .L43:

 

Am I miss something ? I use WinAVR-20040720.
