Bill Hoffman 96242f8022 Add options to run `ldd -u -r` as a "link-what-you-use" tool
Create a LINK_WHAT_YOU_USE target property and corresponding
CMAKE_LINK_WHAT_YOU_USE variable to enable this behavior.
Extend link commands by running `ldd -u -r` to detect shared
libraries that are linked but not needed.

Brad King ea59867187 Run ranlib on archives only if the tool is available
CMakeFindBinUtils sets CMAKE_RANLIB to `:` if it is not available in
order to get a no-op.  This does not work on a Windows host build
environment that runs commands in `cmd` instead of `sh`.  Teach the
Ninja and Makefile generators to simply skip the command if it is `:`.

This this was already done by the Makefile generator since commit
v2.6.0~3161 (BUG: Do not write link script lines that use the ':',
2006-06-18), but only when using a link script.

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 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.

66a9c90c Makefile: Fix multiple custom command outputs regression (#15116)
2015-03-09 09:45:51 -04:00
Brad King 66a9c90c4b Makefile: Fix multiple custom command outputs regression (#15116)
In commit v3.2.0-rc1~272^2~2 (Makefile: Fix rebuild with multiple custom
command outputs, 2014-12-05) we changed the generated makefile pattern
for multiple outputs from

  out1: depends...
          commands...
  out2: out1

to

  out1 out2: depends...
          commands...

This was based on the incorrect assumption that make tools would treat
this as a combined output rule and run the command(s) exactly once for
them.  It turns out that instead this new pattern is equivalent to

  out1: depends...
          commands...
  out2: depends...
          commands...

so the commands may be run more than once.

Some documents suggest using a "dedicated witness" stamp file:

  stamp: depends...
          rm -f stamp
          touch stamp.tmp
          commands...
          mv stamp.tmp stamp
  out1 out2: stamp

However, if the commands fail the error message will refer to the stamp
instead of any of the real outputs, which may be confusing to readers.
Also, this approach seems to have the same behavior of the original
approach that motiviated the above commit: multiple invocations are
needed to bring consumers of the outputs up to date.

Instead we can return to the original approach but add an explicit
touch to each extra output rule:

  out1: depends...
          commands...
  out2: out1
          touch -c out2

This causes make tools to recognize that all outputs have changed and
therefore to execute any commands that consume them.

Brad King 644b4688d7 Makefile: Fix rebuild with multiple custom command outputs (#15116)

much simpler and more reliable than the old multiple-output-pair
infrastructure.

Jiri Malak cb9b1e13e4 Watcom: Use single quote for all file/path items in wlink command
Watcom Linker use single quote if necessary for quoting target name,

Jiri Malak 423009c17f Makefile: Generate single-quoted object lists for Watcom
Drop the CMAKE_NO_QUOTED_OBJECTS internal variable from the Makefile
generators.  The underlying problem is with the Watcom linker, not with
WMake.  The Watcom linker wants object files to be single-quoted.  Add
<LINK-RULE>_USE_WATCOM_QUOTE platform information variables to tell the
generators to use Watcom-style single quotes for object files on link
lines.

On Windows, Watcom uses the GetCommandLine API to get the original
command-line string and do custom parsing that expects single quotes.
On POSIX systems, Watcom approximates the original command line by
joining all argv[] entries separated by a single space.  Therefore we
need to double-quote the single-quoted arguments so that the shell does
not consume them and they are available for the parser to see.
