Hi,
Please find the diff file for dumping tree type stats attached here with.
example:
$ ../stage1-build/gcc/lto1 test_hello.o -fdump-lto-tree-type-stats
Reading object files: test_hello.o
integer_type 3
pointer_type 3
array_type 1
function_type 4
I have pushed the changes on Github repo.
Regards,
Hrishikesh
