Zhengxing li b79169bc85 [llc/opt] Add an option to run all passes twice (#6666) ... This PR pulls the following upstream changes into DXC: [llc/opt] Add an option to run all passes twice (04464cf731) > Lately, I have submitted a number of patches to fix bugs that only occurred when using the same pass manager to compile > multiple modules (generally these bugs are failure to reset some persistent state). > > Unfortunately I don't think there is currently a way to test that from the command line. This adds a very simple flag to both > llc and opt, under which the tools will simply re-run their respective > pass pipelines using the same pass manager on (a clone of the same module). Additionally, we verify that both outputs are > bitwise the same. > > Reviewers: yaron.keren [opt] Fix sanitizer complaints about r254774 (38707c45be) > `Out` can be null if no output is requested, so move any access > to it inside the conditional. Thanks to Justin Bogner for finding > this. This is for the test of this change (ef8761fd3b) to fix #6659. --------- Co-authored-by: github-actions[bot] <github-actions[bot]@users.noreply.github.com> Co-authored-by: Adam Yang <31109344+adam-yang@users.noreply.github.com>		2024-06-24 15:03:08 -07:00
