[En-Nut-Discussion] avr-gcc linker: code size checking

[Dusan Ferbas]

Hi,

when linking with avr-gcc there is a code area (text) + area from where 
data section (in RAM) is initialized. Linker checks only if text area does 
not exceed 128kB limit (description in linker script: 
\WinAVR\avr\lib\ldscripts\avr5.x).

Is there a way how to check if .text + .data fits into 128kB range ? Does 
anybody has modified linker script for this ?
