[avr-gcc-list] End of program symbol

[Simon Han]

Hello,

	I am working on a simple file system for logging data in program  
flash.  I would like my simple file system uses the flash starting at  
the end of my program.  My question is that whether there is any  
support for this.  Specifically, I need a symbol that defines the end  
of program so that I can use it as my starting address for the file  
system.

	Looking at ldscripts/avr5.x, I found that _etext is defined at the  
end of .text section.  However, unlike .data section, there is no  
PROVIDE statement like PROVIDE (__data_end = .) ;

	Would this simply be changing "_etext = . ;" to "PROVIDE (_etext  
= .) ;"?

	Since the default linker script does not use PROVIDE, I just want to  
double check my 'hack' before doing it.

Thank you for any help,
Simon
