[Bug c++/44800] New: DECL_SAVED_TREE is always null on the first FUNCTION_DECL and is not null on the others

[asmprog32 at hotmail dot com]

Look at this simple plugins code

bug.cpp

compile with

g++ -shared -I/usr/local/lib/gcc/i686-pc-linux-gnu/4.5.0/plugin/include -DUNIX
-g -Wall -Werror -O0 -fPIC -DPIC -o libbug.so bug.cpp


than ran this plugins on example.cpp with

g++ -S -fplugin=libbug.so example.cpp

the output


starting libbug
processing example.cpp
unused_f2  0                 <------- decl saved tree is null
unused_f  0xb7409ad4
main  0xb7496c90
function_1  0xb7496c78


now add a function at the end of the file like example2.cpp

and run the plugins on it

starting libbug
processing example2.cpp
unused_f3  0                   <----------- DECL_SAVED_TREE null
unused_f2  0xb754be28          <----------- DECL_SAVED_TREE != null
unused_f  0xb74bead4
main  0xb754bc90
function_1  0xb754bc78


It seem that the last (on file) / first (on list) function_decl has always
DECL_SAVED_TREE == null
