Hello Richard,
I'm still working on the points-to analysis and I am happy to say that
after reviewing the ipa-cp code I was able to generate summaries for
local variables, ssa variables, heap variables, global variables and
functions. I am also using the callback hooks to find out if

Hi
Hello.
I read https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html

Hi,
targeting AMD64 alias x86_64 with -O3, GCC 10.2.0 generates the

Could you file a bugzilla for that?
