AST-tree in GCC

[Johan Bohlin]

Hi I want to extract the complete AST-tree from GCC (using 4.1.2).
I´ve tried to use -fdump-translation-unit but it seems like its dosent
include information in ex. for and if statements. If i use
-fdump-tree-orignal-raw i get each function but not the external variables
if they are not used in the function. My question is... Anyone knows a way
to get all information ? Maybe changing a flag in the source code or
something.

Diego what do you mean by the IL ?

Thomas
-fdump-tree-gimple-raw dosent include global variable that are not used i
functions.
I need something like -fdump-translation-unit that dosent cut the body of
the function.

Question regarding GCC fdump option

[Johan Bohlin]

Hi I have a question regarding gcc or g++ -fdump-tree-all-raw-details (.tu
file). I want to dump the entire C (not C++) AST tree the only way to do
this, without losing any information, is if I use g++  and
-fdump-tree-all-raw-details and i have some kind of error in the file. Can
I in some way change  a flag or edit a method in the source files so i can
use this option without having an error in my c file but get all the
information. Even better would be if i could use gcc.
