Linkers always use object files explicitly specified on the command line
regardless of where they appear. Move them to the front of the list of
linked libraries in so that symbols required by the object files can be
resolved by any library.

CMake uses explicit 'this->' style. Using custom clang-tidy check we can
detect and fix places where 'this->' was missed.

Add an `OPTIMIZE_DEPENDENCIES` target property and supporting
`CMAKE_OPTIMIZE_DEPENDENCIES` variable to optionally enable pruning and
flattening of outgoing dependencies from static libraries. Since they
do not actually link, they only depend on side effects of their
dependencies. Therefore we can drop dependencies that contribute no
side effects.

bd0d03386b cmComputeComponentGraph: Move work out of constructor into Compute() method
Acked-by: Kitware Robot <kwrobot@kitware.com>

The computation of Tarjan's algorithm is an expensive operation which
should not be done in the constructor. Move this work into a dedicated
Compute() method, and call this method explicitly.

Check the result of `GetLinkImplementation` before using it.

generators whether a target should participate in the generated build
system.

When an object library is used via `target_link_libraries`, any targets
listed in the object library's `INTERFACE_LINK_LIBRARIES` closure should
become direct dependencies of the consuming target. However, these were
accidentally left out by `cmComputeTargetDepends::CollectTargetDepends`
because object libraries are encountered through external object sources
first and then added to the `emitted` set which blocks them from being
processed as link dependencies.
This was not noticed by the test case in commit bab24e782c
(target_link_libraries: Propagate dependencies of object libraries,
2018-12-10, v3.14.0-rc1~260^2) because the relevant dependency appears
transitively through the object library target itself.
Re-order the logic to process link dependencies first, and then external
object sources. That way object libraries used via
`target_link_libraries` will be treated as such by dependency analysis.
This also adds missing backtrace information for object libraries used
via `target_link_libraries`. The missing information was mentioned in a
FIXME comment in the RunCMake.FileAPI test added by commit ea0a060168
(fileapi: Add test for codemodel v2, 2018-11-09, v3.14.0-rc1~257^2~7).
That comment itself was dropped by commit a0de350e2f (FileAPI test:
Break gen_check_targets() into JSON files, 2020-02-07), but we can now
update the corresponding location in the `.json` files to have the
now-expected backtrace information.

Set the MinTypeNameLength option to an impossibly high value in order

expressions for later.

Replaced most manual `const_iterator`-based loops and some

094f01d0f0 cleanup: Prefer compiler provided special member functions
55671b41d2 clang-tidy: Use `= default`

Suppress some cases in `Source/cmGeneratorExpressionNode.cxx` and
`Source/cmUVHandlePtr.h` where a few older compilers require a
user-defined default constructor (with `{}`).
|
|/ |
|
|
|
|

Reduce the number of files relying on `cmake.h`.
|
|
|
|
|

Carry backtraces on target dependency edges to refer to the line in
project code that caused the edge to appear.
|
|
|
|
|
|
| |
Carry a backtrace on every link item, not just link implementation
items. For now the non-impl items will still have empty backtraces at
runtime, but this will allow us to introduce values over time.

If two imported targets in different directories have the same name we
should still be able to propagate transitive link dependencies from
both. Fix the target and link dependency analyzers to de-duplicate
targets using target pointers rather than target names since the
pointers will not be duplicated even if the names are.
Issue: #18345

Avoid exposing the item name implicitly as std::string. When the item
is a target, avoid storing a second copy of its name.
Most link item construction is paired with calls to `FindTargetToLink`
to get the possible target pointer. Rename these methods to
`ResolveLinkItem` and refactor them to construct the entire item.

Note: This only allows `OBJECT` libraries to be on the right-hand side
of `target_link_libraries` but still does not link its object-files to
the target on the left-hand side.

- Use `std::move` while inserting temporary results into vectors.
- Change `push_back` to `emplace_back` where appropriate.

Changes done via `clang-tidy` with some manual fine-tuning
for the variable naming and `auto` type deduction
where appropriate.

Add an index to Change cmLocalGenerator::GeneratorTargets for faster lookup by
name.
Also changed a bunch of uses of cmLocalGenerator::GetGeneratorTargets() to take
const references instead of copying the vector.
Represent generator targets as a map (name -> target) to make name lookups more
efficient instead of looping through the entire vector to find the desired one.

`AddInterfaceDepends` is only called from `CollectTargetDepends` inside
our loop over all configurations so it doesn't need its own such loop.
|
|
|
|
|

|

Fix `AddInterfaceDepends` to combine all configurations using the
same approach that `CollectTargetDepends` does.

Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool. Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience. Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.
Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices. It also references version control
history for more precise information. Therefore we no longer need to spell
out the list of Contributors in each source file notice.
Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.

Run the `Utilities/Scripts/clang-format.bash` script to update
all our C++ code to a new style defined by `.clang-format`.
Use `clang-format` version 3.8.

Modern editors provide plenty of ways to visually separate functions.
Drop the explicit comments that previously served this purpose.
Use the following command to automate the change:
$ git ls-files -z -- \
"*.c" "*.cc" "*.cpp" "*.cxx" "*.h" "*.hh" "*.hpp" "*.hxx" |
egrep -z -v "^Source/cmCommandArgumentLexer\." |
egrep -z -v "^Source/cmCommandArgumentParser(\.y|\.cxx|Tokens\.h)" |
egrep -z -v "^Source/cmDependsJavaLexer\." |
egrep -z -v "^Source/cmDependsJavaParser(\.y|\.cxx|Tokens\.h)" |
egrep -z -v "^Source/cmExprLexer\." |
egrep -z -v "^Source/cmExprParser(\.y|\.cxx|Tokens\.h)" |
egrep -z -v "^Source/cmFortranLexer\." |
egrep -z -v "^Source/cmFortranParser(\.y|\.cxx|Tokens\.h)" |
egrep -z -v "^Source/cmListFileLexer\." |
egrep -z -v "^Source/cm_sha2" |
egrep -z -v "^Source/(kwsys|CursesDialog/form)/" |
egrep -z -v "^Utilities/(KW|cm).*/" |
xargs -0 sed -i '/^\(\/\/---*\|\/\*---*\*\/\)$/ {d;}'
This avoids modifying third-party sources and generated sources.

Sort include directives within each block (separated by a blank line) in
lexicographic order (except to prioritize `sys/types.h` first). First
run `clang-format` with the config file:
---
SortIncludes: false
...
Commit the result temporarily. Then run `clang-format` again with:
---
SortIncludes: true
IncludeCategories:
- Regex: 'sys/types.h'
Priority: -1
...
Commit the result temporarily. Start a new branch and cherry-pick the
second commit. Manually resolve conflicts to preserve indentation of
re-ordered includes. This cleans up the include ordering without
changing any other style.
Use the following command to run `clang-format`:
$ git ls-files -z -- \
'*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' |
egrep -z -v '(Lexer|Parser|ParserHelper)\.' |
egrep -z -v '^Source/cm_sha2' |
egrep -z -v '^Source/(kwsys|CursesDialog/form)/' |
egrep -z -v '^Utilities/(KW|cm).*/' |
egrep -z -v '^Tests/Module/GenerateExportHeader' |
egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' |
xargs -0 clang-format -i
This selects source files that do not come from a third-party.
