Re: Code Optimization

[Emre Omacan]

Hi Garth,

Here is the code generated by the gcc compiler with optimization -O3 and

no stack frame generation.

command line : m68k-palmos-gcc -O3 -S -fomit-frame-pointer test.c

test:
 move.w 4(%sp),%d0
 move.w %d0,%d1
 lsl.w #5,%d1
 lsl.w #6,%d0
 add.w %d1,%d0
 rts
 nop

It seems that the gcc optimizer does a pretty good job.

Emre
