Brian Gesiak d481df5310 [Option] For typo '-foo', suggest '--foo'
Summary:
https://reviews.llvm.org/rL321877 introduced the `OptTable::findNearest`
method, to find the closest edit distance option for a given string.
However, the implementation contained a bug: for a typo `-foo` with an
edit distance of 1 away from a valid option `--foo`, `findNearest`
would suggest a nearby option of `foo`. That is, the result would not
include the `--` prefix, and so was not a valid option.

Fix the bug by ensuring that the prefix string is initialized to one of
the valid prefixes for the option.

Brian Gesiak 7b84de792b [Option] Add 'findNearest' method to catch typos
Summary:
Add a method `OptTable::findNearest`, which allows users of OptTable to
check user input for misspelled options. In addition, have llvm-mt
check for misspelled options. For example, if a user invokes
`llvm-mt /oyt:foo`, the error message will indicate that while an
option named `/oyt:` does not exist, `/out:` does.

The method ports the functionality of the `LookupNearestOption` method
from LLVM CommandLine to libLLVMOption. This allows tools like Clang
and Swift, which do not use CommandLine, to use this functionality to
suggest similarly spelled options.

As room for future improvement, the new method as-is cannot yet properly suggest
nearby "joined" options -- that is, for an option string "-FozBar", where
"-Foo" is the correct option name and "Bar" is the value being passed along
with the misspelled option, this method will calculate an edit distance of 4,
by deleting "Bar" and changing "z" to "o". It should instead calculate an edit
distance of just 1, by changing "z" to "o" and recognizing "Bar" as a
value. This commit includes a disabled test that expresses this limitation.

Yuka Takahashi 5e7071f5d7 [Bash-autocompletion] Add support for static analyzer flags
Summary:
This is a patch for clang autocomplete feature.

It will collect values which -analyzer-checker takes, which is defined in
clang/StaticAnalyzer/Checkers/Checkers.inc, dynamically.
First, from ValuesCode class in Options.td, TableGen will generate C++
code in Options.inc. Options.inc will be included in DriverOptions.cpp, and
calls OptTable's addValues function. addValues function will add second
argument to Option's Values class. Values contains string like "foo,bar,.."
which is handed to Values class
in OptTable.

We don't want to autocomplete flags whose Flags class has `NoDriverOption` when argv[1] is not `-cc1`.

Another idea for this implementation is to make --autocomplete a cc1

and CC1 options in unified manner.

Chandler Carruth 6bda14b313 Sort the remaining #include lines in include/... and lib/....
I did this a long time ago with a janky python script, but now
clang-format has built-in support for this. I fed clang-format every
line with a #include and let it re-sort things according to the precise
LLVM rules for include ordering baked into clang-format these days.

I've reverted a number of files where the results of sorting includes
isn't healthy. Either places where we have legacy code relying on
particular include ordering (where possible, I'll fix these separately)
or where we have particular formatting around #include lines that
I didn't want to disturb in this patch.

This patch is *entirely* mechanical. If you get merge conflicts or
anything, just ignore the changes in this patch and run clang-format
over your #include lines in the files.

Sorry for any noise here, but it is important to keep these things
stable. I was seeing an increasing number of patches with irrelevant
re-ordering of #include lines because clang-format was used. This patch
at least isolates that churn, makes it easy to skip when resolving
conflicts, and gets us to a clean baseline (again).

Richard Smith 4e1ec636e1 ArgList: cache index ranges containing arguments with each ID
Improve performance of argument list parsing with large numbers of IDs and
large numbers of arguments, by tracking a conservative range of indexes within
the argument list that might contain an argument with each ID. In the worst
case (when the first and last argument with a given ID are at the opposite ends
of the argument list), this still results in a linear-time walk of the list,
but it helps substantially in the common case where each ID occurs only once,
or a few times close together in the list.

This gives a ~10x speedup to clang's `test/Driver/response-file.c`, which
constructs a very large set of command line arguments and feeds them to the
clang driver.

This patch contains the LLVM side of the fix of PR17239.

This bug that happens because the /link (clang-cl.exe argument) is
marked as "consume all remaining arguments". However, when inside a
response file, /link should only consume all remaining arguments inside
the response file where it is located, not the entire command line after
expansion.

My patch will change the semantics of the RemainingArgsClass kind to
always consume only until the end of the response file when the option
originally came from a response file. There are only two options in this
class: dash dash (--) and /link.
