Daniel Pfeifer 618fb23fc9 Pass arguments that are not modified as const&.
Use clang-tidy's performance-unnecessary-value-param checker to find
value parameter declarations of expensive to copy types that are not
modified inside the function.  Ignore findings in kwsys.
After applying the fix-its, manually change `const T&` to `T const&`.

Brad King c13408279f Add a variable to specify language-wide system include directories
Create a `CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES` variable to specify
system include directories for for `<LANG>` compiler command lines.
This plays a role for include directories as the existing
`CMAKE_<LANG>_STANDARD_LIBRARIES` variable does for link libraries.

Brad King 0ac18d40c8 Remove `//------...` horizontal separator comments
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.

Brad King 64b5520346 Isolate formatted streaming blocks with clang-format off/on
The clang-format tool can do a good job formatting most code, but
well-organized streaming blocks are best left manually formatted.

Find blocks of the form

    os <<
      "...\n"
      "...\n"
      ;

using the command

    $ git ls-files -z -- Source |
      egrep -v -z '^Source/kwsys/' |
      xargs -0 pcregrep -M --color=always -B 1 -A 1 -n \
        '<<[^\n]*\n(^ *("[^\n]*("|<<|;)$|;)\n){2,}'

Find blocks of the form

    os << "...\n"
       << "...\n"
       << "...\n";

using the command

    $ git ls-files -z -- Source |
      egrep -v -z '^Source/kwsys/' |
      xargs -0 pcregrep -M --color=always -B 1 -A 1 -n \
        '<<[^\n]*\n(^ *<<[^\n]*(\\n"|<<|;)$\n){2,}'

Surround such blocks with the pair

    /* clang-format off */
    ...
    /* clang-format on */

in order to protect them from update by clang-format.  Use the C-style
`/*...*/` comments instead of C++-style `//...` comments in order to
prevent them from ever being swallowed by re-formatting of surrounding
comments.

Brad King e1c7747253 Format include directive blocks and ordering with clang-format
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.

Brad King 3144857e1e Avoid depending on CMAKE_ROOT cache entry internally (#16015)
Use cmSystemTools::GetCMakeRoot() which always knows the location of our
resources.  Do not depend on CMAKE_ROOT because the user could unset it
from the cache.

Brad King 72e0dc58d3 Diagnose recursive project/enable_language without crashing (#15999)
Calling `project()` or `enable_language()` from a toolchain file will
infinitely recurse since those commands load the toolchain file.
Diagnose and reject this case with an error message instead of crashing
when the stack eventually overflows.

Brad King da490e1159 cmake-gui: Fix cmState initialization when changing generators (#15959)
Refactoring in commit v3.3.0-rc1~29^2~1 (cmState: Host some state from
the cmGlobalGenerator, 2015-05-24) moved storage of some generator
traits over to cmState.  However, it accidentally removed initialization
of the values from the cmGlobalGenerator constructor.  This is needed
because generator subclasses update the settings in their constructors.
Since a single cmState instance is shared across multiple build trees by
cmake-gui, initializing the values in its constructor is not enough.
Fix this by restoring the needed initializations to the
cmGlobalGenerator constructor.

Brad King 9b7d5871b8 Improve internal generator target structure lookup
In commit v3.5.0-rc1~272^2~6 (cmGlobalGenerator: Add FindGeneratorTarget
API, 2015-10-25) a lookup was implemented via linear search.  Replace it
with an efficient data structure.

Brad King 6cbf6a5197 Fix internal target lookup performance regression
Refactoring in commit v3.5.0-rc1~272^2~13 (cmGlobalGenerator: Remove
direct storage of targets, 2015-10-25) replaced an efficient data
structure mapping from target name to cmTarget instance with a linear
search.  Lookups through cmGlobalGenerator::FindTarget are done a lot.
Restore the efficient mapping structure with a name indicating its
purpose.

See also Herb Sutter's article on the "most important const":
http://herbsutter.com/2008/01/01/gotw-88-a-candidate-for-the-most-important-const/

When running the CMake daemon on the KDevelop build dir, this removes
some hundreds of thousands of temporary allocations.

This hotspot was found with heaptrack.

Brad King ffa2a8c967 cmSystemTools: Rename OUTPUT_NORMAL to OUTPUT_FORWARD to clarify its purpose
The OUTPUT_NORMAL value is not really "normal" and has only one caller.
Rename it to OUTPUT_FORWARD to clarify that we are explicitly forwarding

Stephen Kelly 4ce9742ae3 Alias: Fix access at generate-time (#15832)
Commit c389f8bb (cmLocalGenerator: Port Find method away from
GetGeneratorTarget, 2015-10-25) ported the implementation of
FindGeneratorTargetToUse away from the FindTargetToUse method,
but neglected to handle alias targets.

The latter method has a parameter to determine whether to
include alias targets in the search, but as that is only
needed at configure time, this generate-time equivalent does
not need the condition.
