Add a `Fortran_COMPILER_LAUNCHER` target property like those added for C
and CXX by commit v3.4.0-rc1~450^2 (Add options to launch the compiler
through tools like ccache or distcc, 2015-06-04) and CUDA by commit
v3.10.0-rc1~531^2 (CUDA: Add option to run the compiler through launcher
tools, 2017-06-09).
Fixes: #17499
Since commit v3.0.0-rc1~448^2 (Ninja: use deps = gcc/msvc feature,
2013-10-18) the value of the `DEP_FILE` binding already includes the
needed quoting to refer to the file. However, that commit forgot to
update one of the `$DEP_FILE` references to not be quoted anymore.
The offending code path currently only affects cmcldeps for RC.
Remove the extra quoting now.
Fixes: #17298
This commit changes the internal -E__run_iwyu to be -E__run_co_compile. This
is used for co-compile commands. These are tools that want to mirror the
compiler. For each compiler invocation the tool will be invoked first. This
started as a way to implement include what you use (iwyu), but has expanded
to include cpplint, cppcheck and others. Likely there will be more in the
future as well. This commit implements each one in its own function and
provides a way to add additional ones in the future with less work.
Create a `<LANG>_CPPCHECK` target property (initialized by a
`CMAKE_<LANG>_CPPCHECK` variable) to specify a `cppcheck` command line
to be run along with the compiler.
The Ninja generator preprocesses and compiles separately for Fortran.
When compiling, tell gfortran that the source is already preprocessed so
that it will honor the `# <line>` directives when producing diagnostics
messages.

Command line argument passed to the internal tool "cmake_ninja_dyndep"
could hit MAX_ARG_STRLEN on Linux for projects with a large code base.
To prevent such problems, a response file was opted for argument transfer
in all cases, not only on Windows.

The internal tool "cmake_ninja_depends" now supports reading the list of ddi
files from a reponse file to circumvent Windows command line length limits.
Use this response file for dyndep rule on Windows.

Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !430
Previously, given two libraries, X and Y where X depends on Y, all
object compilations of X would require the Y library to have been linked
before being compiled. This is not necessary and can instead be loosened
such that object compilations of X only depend on the order-only
dependencies of Y to be completed. This is to ensure that generated
sources, headers, custom commands, etc. are completed before X starts to
compile its objects.
This should help build performance in projects with many libraries which
cause a deep library dependency chain. Previously, a library at the
bottom would not start compilation until after all other libraries
completed, but now only its link step needs to wait and its compilation
jobs can be run in parallel with other tasks.
Fixes: #15555
Each target's dyndep file generation depends on loading information
generated by the same step in its dependencies. Add an explicit
ordering dependency to ensure the needed information is available.
Without the explicit ordering dependency we were abusing the more
general target ordering rules through the preprocessor rules generating
the `.ddi` files used as input to dyndep file generation.
Work around upstream ninja issue 1251 by converting include directories
used by our Fortran dependency scanner to the same path format that we
use in preprocessor `-I` flags and in the `build.ninja` manifest.
Fixes: #16722
The `WINDOWS_EXPORT_ALL_SYMBOLS` target property exports all symbols
found in object files explicitly given to the linker. However, the
linker may also find additional symbols in dependencies and copy them
into the linked binary (e.g. from `msvcrt.lib`). Provide a way to
export an explicit list of such symbols by adding a `.def` file as a
source file.
Fixes: #16473
Use `cmGeneratorTarget::ModuleDefinitionInfo` to combine the
implementation of `WINDOWS_EXPORT_ALL_SYMBOLS` with that of using a
`.def` file as a source. Only one of these could be used within a
single target before anyway.
Create a `ModuleDefinitionInfo` structure for each configuration of a
target to hold corresponding information about the selected module
definition file (`.def` source).
This reverts commit v3.7.0-rc1~275^2 (Ninja: Use full path for all
source files, 2016-08-05). Unfortunately using absolute paths can
cause incorrect rebuilds due to ninja limitations. The ninja
manual [1] explains:
> ... using absolute paths, your depfile may result in a mixture of
> relative and absolute paths. Paths used by other build rules need
> to match exactly.
Passing an absolute path to a source file to the compiler while using a
relative path in the ninja build manifest can cause such mixture and
lead to incorrect rebuilds. Simply revert the change for now.
Note that there was a follow-up to the original change in commit
v3.7.0-rc2~10^2 (Ninja: Fix RC language depfile generation with
cmcldeps, 2016-10-13). We don't need to revert that because that
change made the relevant code cleverly adapt to whatever variable
we use to reference the source file.

Issue: #13894
Create a `<LANG>_CPPLINT` target property (initialized by a
`CMAKE_<LANG>_CPPLINT` variable) to specify a `cpplint` style checker
command line to be run along with the compiler.
Call sites of `ExpandRuleVariables` are now responsible for inserting
the `RULE_LAUNCH_{COMPILE,LINK,CUSTOM}` values in rule command lines.
Audit all call sites and add a comment to each one that does not insert
a launcher to explain why.
Change the default compile PDB file name for static libraries to match
the Visual Studio default of using the logical target name. This may be
incompatible with existing behavior but `COMPILE_PDB_NAME` documents
that the default is unspecified. Projects depending on a particular
name should set the property.
Closes: #16438
This allows users to specify different genex-based compile flags for
each file in a target, e.g. compiling just a single file with `Od/Ox` in
release builds on Visual Studio.
