[PATCH] D128796: [SCCP] Simplify CFG in SCCP as well

[Changpeng Fang via Phabricator via llvm-commits]

cfang added a comment.

This patch triggered a correctness issue in running mixbench-ocl-alt.
I am not familiar with the CFG in SCCP pass at all. But the comments 
in the code seems suggest we should not change the CFG:

// If we decided that there are basic blocks that are dead in this function,
// delete their contents now.  Note that we cannot actually delete the blocks,
// as we cannot modify the CFG of the function.
