[Bug c++/44800] DECL_SAVED_TREE is always null on the first FUNCTION_DECL and is not null on the others
--- Comment #11 from asmprog32 at hotmail dot com 2010-07-04 09:39 --- The problem is that i followed also external documentation, where PLUGIN_OVERRIDE_GATE is used to analyse AST. GCC documentation say to use PLUGIN_PRE_GENERICIZE and infact it work, so it is a my wrong. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44800

--- Comment #5 from asmprog32 at hotmail dot com 2010-07-03 11:22 --- (In reply to comment #4) bugzilla is not a plugin support forum Infact is not a request of help, DECL_SAVED_TREE is systematicaly Null ONLY and ALWAYS on the last FUNCTION_DECL, i has thinked this is the normal behaviour. The code is given only to reproduce the issue. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44800

--- Comment #7 from asmprog32 at hotmail dot com 2010-07-04 00:39 --- (In reply to comment #6) Pietro, Please explain what is happening and what do you expect to happen, and why do you expect that. If you are having troubles about using gcc, please ask in gcc-help first. Ok inserting a gcc callback into PLUGIN_OVERRIDE_GATE and analyzing the AST systematicaly the last function in the file, has no body ( DECL_SAVED_TREE == null ) An example A file has 3 functions (with body), the AST generated report a body (DECL_SAVED_TREE != null ) on function 1, 2 not on function 3 (last one) If i add another function , the AST generated report a body on function 1 2 3 not on function 4 . and so on What i expect is that all functions must have the body (DECL_SAVED_TREE != null). The code attached are examples to reproduce what i have explained. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44800
