code reduce

Mustafa Kara

Hi All

I'm writing a software for 8 bit architecture using uvision 2. But when I try to compile my project using uvision2 it gives the following error

*** ERROR L107: ADDRESS SPACE OVERFLOW
.
.
.
Program Size: data=171.7 xdata=15942 code=65617

my target system has only 64KB code space it seems overflow.

How can I reduce code size for this application.

I'm using Code Optimisation Level 9 from uvision2.

any idea

    I wouldn't be surprised if the new directive issues a warning when it removes code?

    Nope - no warning. IF you specify this directive, the linker assumes you know what you're doing.

    You do, however, get a nice listing of all the memory you just saved.
