RE: [avr-gcc-list] Option to remove unused trampoline space gives bad link

[Stu Bell]

Hi all,

Just a quick update -- I've spent over a day now trying to chase it
down.  The generated code looks fine, but it doesn't work.  My error
seems to be occurring in the task switching code in FreeRTOS.  None of
the code is currently over the 128K Flash page boundary, so I'm still in
a 16-bit PC address.  *sigh*

More info as I get it.

Best regards,

This option is very interesting, can free a very large amount of flash.

I've tried but there must be something wrong, cause my (large) code was 
not working anymore. I'll try to supply a testcase but it's not easy, 
cause I have to look directly in elf file.

Please put me in CC of the bug too, maybe I can add more info to bug 
report soon.
