It's an accident that we started return asbolute paths from
FileEntry::getName for all relative paths. Prepare for getName to get
(closer to) return the requested path. Note: conceptually it might make
sense for the dependency scanner to allow relative paths and have the
DependencyConsumer decide if it wants to make them absolute, but we
currently document that it's absolute and I didn't want to change
behaviour here.

If two different texts are inserted at the same offset, clang-apply-replacements prints the conflict error and discards all fixes. This patch adds support for adjusting conflict offset and keeps running to continually fix them.
https://godbolt.org/z/P938EGoxj doesn't have any fixes when I run run-clang-tidy.py to generate a YAML file with clang-tidy and fix them with clang-apply-replacements. The YAML file has two different header texts insertions at the same offset, unlike clang-tidy with '-fix', clang-apply-replacements does not adjust for this conflict.

The fixes from the YAML file can refer to relative paths.
Those relative paths are meant to be resolved relative to the
corresponding `build directory`.
However, `clang-apply-replacements` currently interprets all
paths relative to its own working directory. This causes issues,
e.g., when `clang-apply-replacements` is run from outside of
the original build directory.
This commit adjusts `clang-apply-replacements` to take the build
directory into account when resolving relative file paths.

Summary:
clang-apply-replacements currently deduplicates all diagnostic replacements. However if you get a duplicated replacement from one TU then its expected that it should not be deduplicated. This goes some way to solving [[ https://bugs.llvm.org/show_bug.cgi?id=45150 | export-fixes to yaml adds extra newlines and breaks offsets. ]]
Take this example yaml.
```

ReplacementText: ' {'

Offset: 28
Length: 0
ReplacementText: '

...```
The current behaviour is to deduplicate the text insertions at Offset 28 and only apply one of the replacements.
However as both of these replacements came from the same translation unit we can be confident they were both meant to be applied together
The new behaviour won't deduplicate the text insertion and instead insert both of the replacements.
If the duplicate replacement is found inside different translation units (from a header file change perhaps) then they will still be deduplicated as before.

The FileManager has been updated to return llvm::ErrorOr from getFile
and getDirectory, this commit updates all the callers of those APIs from
clang.
llvm-svn: 367617
Summary:
Motivation/Context: in the code review system integrating with clang-tidy,
clang-tidy doesn't provide a human-readable description of the fix. Usually
developers have to preview a code diff (before vs after apply the fix) to
understand what the fix does before applying a fix.
This patch proposes that each clang-tidy check provides a short and
actional fix description that can be shown in the UI, so that users can know
what the fix does without previewing diff.
This patch extends clang-tidy framework to support fix descriptions (will add implementations for
existing checks in the future). Fix descriptions and fixes are emitted via diagnostic::Note (rather than
attaching the main warning diagnostic).
Before this patch:
```
void MyCheck::check(...) {
...
diag(loc, "my check warning") << FixtItHint::CreateReplacement(...);
}
```
After:
```
void MyCheck::check(...) {
...
diag(loc, "my check warning"); // Emit a check warning
diag(loc, "fix description", DiagnosticIDs::Note) << FixtItHint::CreateReplacement(...); // Emit a diagnostic note and a fix
}
```

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.

Summary:
After r329813, clang-apply-replacements stopped deduplicating identical
replacements; however, tools like clang-tidy relies on the deduplication of
identical dignostics replacements from different TUs to apply fixes correctly.
This change partially roll back the behavior by deduplicating changes from
diagnostics. Ideally, we should deduplicate on diagnostics level, but we need to
figure out an effecient way.

Patch by Jeremy Demeule.
llvm-svn: 329813
We currently use target_link_libraries without an explicit scope
specifier (INTERFACE, PRIVATE or PUBLIC) when linking executables.
Dependencies added in this way apply to both the target and its
dependencies, i.e. they become part of the executable's link interface
and are transitive.
Transitive dependencies generally don't make sense for executables,
since you wouldn't normally be linking against an executable. This also
causes issues for generating install export files when using
LLVM_DISTRIBUTION_COMPONENTS. For example, clang has a lot of LLVM
library dependencies, which are currently added as interface
dependencies. If clang is in the distribution components but the LLVM
libraries it depends on aren't (which is a perfectly legitimate use case
if the LLVM libraries are being built static and there are therefore no
run-time dependencies on them), CMake will complain about the LLVM
libraries not being in export set when attempting to generate the
install export file for clang. This is reasonable behavior on CMake's
part, and the right thing is for LLVM's build system to explicitly use
PRIVATE dependencies for executables.
Unfortunately, CMake doesn't allow you to mix and match the keyword and
non-keyword target_link_libraries signatures for a single target; i.e.,
if a single call to target_link_libraries for a particular target uses
one of the INTERFACE, PRIVATE, or PUBLIC keywords, all other calls must
also be updated to use those keywords. This means we must do this change
in a single shot. I also fully expect to have missed some instances; I
tested by enabling all the projects in the monorepo (except dragonegg),
and configuring both with and without shared libraries, on both Darwin
and Linux, but I'm planning to rely on the buildbots for other
configurations (since it should be pretty easy to fix those).
Even after this change, we still have a lot of target_link_libraries
calls that don't specify a scope keyword, mostly for shared libraries.
I'm thinking about addressing those in a follow-up, but that's a
separate change IMO.
