templated interface. So far, every single IR unit I can come up with has address-identity. That is, when two units of IR are both active in LLVM, their addresses will be distinct of the IR is distinct. This is clearly true for Modules, Functions, BasicBlocks, and Instructions. It turns out that the only practical way to make the CGSCC stuff work the way we want is to make it true for SCCs as well. I expect this pattern to continue. When first designing the pass manager code, I kept this dimension of freedom in the type parameters, essentially allowing for a wrapper-type whose address did not form identity. But that really no longer makes sense and is making the code more complex or subtle for no gain. If we ever have an actual use case for this, we can figure out what makes sense then and there. It will be better because then we will have the actual example in hand. While the simplifications afforded in this patch are fairly small (mostly sinking the '&' out of many type parameters onto a few interfaces), it would have become much more pronounced with subsequent changes. I have a sequence of changes that will completely remove the code duplication that currently exists between all of the pass managers and analysis managers. =] Should make things much cleaner and avoid bug fixing N times for the N pass managers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225723 91177308-0d34-0410-b5e6-96231b3b80d8 |
