Hi,
How do we identify whether a function is a pure or a const function?
Is there any flag associated with its cgraph_node or the tree node
(decl of cgraph_node)?
Thanks,

You'll want to look into ipa-pure-const.c.

I had a look at the file ipa-pure-const.c. I have wriiten a Simple IPA
Pass which identifies pure and const functions in the program. I have
inserted this pass after ipa-pta pass which is executed after
ipa-pure-const pass. Also, the option -fipa-pure-const is enabled.
I am using DECL_PURE_P(t) and
I am writing a Simple IPA Pass which is inserted after ipa-pta. This
pass identifies whether a chain of recurrence is built by gcc or not.
I have used tree_is_chrec(t) to check if t represents chain of
recurrence and function find_var_scev_info(bb, var) to obtain the
scev information generated (wh
