Hello World IPA pass with call to create_version_clone_with_body
Hello,
I am developing a simple ipa pass that versions a single call site to method
`bar`.
I am using `create_version_clone_with_body` instead of `create_version_clone`
because I want to modify `foo`'s body.
In my test case I have three functions
* main
* foo
* bar
In my simple ipa pass, I have implemented the execute stage to call
`create_version_clone_with_body` for method bar.
I am compiling my test with -flto-partition=none, which if I understand
correctly means the execution stage should have access to the method bodies.
You can apply the patch to master (commit id:
17a2c588c29f089d3c2a36df47175bbdf376e399)
I also add my test case.
After compiling with my patch, to trigger the bug just modify the Makefile to
point to the version of gcc with the patch and `make`.
