I see the patch doesn't have any standalone testcases. Do you have some Erick?

It seems like that has much of the needed machinery already and we wouldn't need to insert writes to propagate the constant information?

Currently, this patch can be applied against this commit on master branch. commit 3cce71b23f6ed221b4335b600e718d79903cc83d Date: Wed Dec 4 20:04:10 2019 + git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@278975 138bc75d-0d04-0410-961f-82ee72b054a4 This patch works on the previous patch by eliminating bugs. Currently, all SPEC CPU 2017 benchmarks can be compiled with this patch and run successfully. Furthermore, it detects several constants that can be propagated in 12 of the SPEC CPU benchmarks.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92538 --- Comment #4 from Christoph Müllner --- Early tests with this pass showed that a bunch of SPEC CPU2017 benchmarks benefit from this. For example, the written-once global variable TTSize of sjeng is eliminated by this pass.
