Yes, but not vice-versa. Take .bss for example which is allocatable but not 
loadable.

Overlays.

These are not specific to avr-gcc.

Subject: [avr-gcc-list] GCC: Diffrence b/w lodable & allocatable sections ?

Hi, 

lodable & allocatable sections 

I am trying to work on linker scripts. I am bit stuck at starting point please 
clarify it. 
If some .data section is loaded in memory then definitely it should be 
allocated some memory. This link also specifies that some section are lodable 
but not allocatable. I am confused over here. What is the diffrence b/w lodable 
& allocatable sections  ?
Can some someone suggest example related to it, so that it is clarified to me.
Linker script : 
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/4/html/Using_ld_the_GNU_Linker/scripts.html
Please suggest
