With `-view-edge-bundles`, before the change, the dot file output is
kinda like
```dot
digraph {
"%bb.0" [ shape=box ]
0 -> "%bb.0"
"%bb.0" -> 1
"%bb.0" -> "%bb.1" [ color=lightgray ]
"%bb.0" -> "%bb.6" [ color=lightgray ]
"%bb.1" [ shape=box ]
1 -> "%bb.1"
"%bb.1" -> 1
"%bb.1" -> "%bb.2" [ color=lightgray ]
"%bb.1" -> "%bb.6" [ color=lightgray ]
"%bb.2" [ shape=box ]
1 -> "%bb.2"
"%bb.2" -> 1
"%bb.2" -> "%bb.3" [ color=lightgray ]
"%bb.3" [ shape=box ]
1 -> "%bb.3"
"%bb.3" -> 2
"%bb.3" -> "%bb.4" [ color=lightgray ]
"%bb.4" [ shape=box ]
2 -> "%bb.4"
"%bb.4" -> 2
"%bb.4" -> "%bb.4" [ color=lightgray ]
"%bb.4" -> "%bb.5" [ color=lightgray ]
"%bb.5" [ shape=box ]
2 -> "%bb.5"
"%bb.5" -> 1
"%bb.5" -> "%bb.6" [ color=lightgray ]
"%bb.5" -> "%bb.3" [ color=lightgray ]
"%bb.6" [ shape=box ]
1 -> "%bb.6"
"%bb.6" -> 3
}
```
However, the graph output by graphviz is
The node name corresponding to the MBB is incorrect.
After the change, the node name is consistent with MBB's name.
Looking at the Doxygen-generated documentation for the llvm namespace
currently shows all sorts of random comments from different parts of the
codebase. These are mostly caused by:
- File doc comments that aren't marked with \file, so they're attached to
the next declaration, which is usually "namespace llvm {".
- Class doc comments placed before the namespace rather than before the
class.
- Code comments before the namespace that (in my opinion) shouldn't be
extracted by doxygen at all.
This commit fixes these comments. The generated doxygen documentation now
has proper docs for several classes and files, and the docs for the llvm
and llvm::detail namespaces are now empty.

EdgeBundles.h has no use for it.
This file lists every pass in LLVM, and is included by Pass.h, which is very popular. Every time we add, remove, or rename a pass in LLVM, it caused lots of recompilation. I found this fact by looking at this table, which is sorted by the number of times a file was changed over the last 100,000 git commits multiplied by the number of object files that depend on it in the current checkout: recompiles touches affected_files header 342380 95 3604 llvm/include/llvm/ADT/STLExtras.h 314730 234 1345 llvm/include/llvm/InitializePasses.h 307036 118 2602 llvm/include/llvm/ADT/APInt.h 213049 59 3611 llvm/include/llvm/Support/MathExtras.h 170422 47 3626 llvm/include/llvm/Support/Compiler.h 162225 45 3605 llvm/include/llvm/ADT/Optional.h 158319 63 2513 llvm/include/llvm/ADT/Triple.h 140322 39 3598 llvm/include/llvm/ADT/StringRef.h 137647 59 2333 llvm/include/llvm/Support/Error.h 131619 73 1803 llvm/include/llvm/Support/FileSystem.h Before this change, touching InitializePasses.h would cause 1345 files to recompile. After this change, touching it only causes 550 compiles in an incremental rebuild. Reviewers: bkramer, asbirlea, bollu, jdoerfert Differential Revision: https://reviews.llvm.org/D70211
This patch applies clang-tidy's bugprone-argument-comment tool
to LLVM, clang and lld source trees. Here is how I created this

to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
As part of the unification of the debug format and the MIR format, print MBB references as '%bb.5'.
