Treedump output

[Svein E. Seldal]

Hello,

This might sound as a silly question, but I'm kind of stuck, and I cant 
find anyting that helps in the sources/docs/internet. Can I get some 
help please? :)

The docs sais that you can use "-da" and/or "-fdump-tree-all" to get 
dump outputs. But when I try this on avr-gcc or its cc1, nothing 
happens. Are there some configure option I have forgotten when building 
the tools. Or can it be some commandline option that I need add to get 
it to provide the output I want?

I have compiled gcc HEAD for the avr target with the configure option 
"../configure --target=avr --disable-nls --enable-languages=c". And the 
compiler command that doesnt provide the dumps are: "avr-gcc -da 
-fdump-tree-all -c tree.c". The same thing happens if I use the 
-fdump-tree-all command to cc1 directly. It seems to recognize the 
option, but it doesnt provide any output.


Regards,
Svein
