* Ninja: Use "deps = msvc" only for C and CXX (#15253)Brad King2015-01-291-29/+23
| | | | | | | | The "/showIncludes" flag is only available with MS C and C++ compilers, and on compilers that "simulate" them (like Intel for Windows). Fix our logic to choose this type only for MS tools with these languages. All other cases need to use "deps = gcc" and define DEP_FILE in the build rule.

| * Normalize OBJECT_DEPENDS paths to match custom commands (#15366)Brad King2015-01-281-0/+8
| | | | | | | | | | | | | | | | | | | | Custom command path normalization added in commit v3.1.0-rc1~471^2 (add_custom_command: Normalize OUTPUT and DEPENDS paths, 2014-05-28) broke use of OBJECT_DEPENDS to bring in custom commands because the latter paths were not normalized too. Normalize them and add a test case. Reported-by: Daniel v. Gerpen

* | Add an option for explicit BYPRODUCTS of custom commands (#14963)Brad King2014-11-141-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A common idiom in CMake-based build systems is to have custom commands that generate files not listed explicitly as outputs so that these files do not have to be newer than the inputs. The file modification times of such "byproducts" are updated only when their content changes. Then other build rules can depend on the byproducts explicitly so that their dependents rebuild when the content of the original byproducts really does change. This "undeclared byproduct" approach is necessary for Makefile, VS, and Xcode build tools because if a byproduct were listed as an output of a rule then the rule would always rerun when the input is newer than the byproduct but the byproduct may never be updated. Ninja solves this problem by offering a 'restat' feature to check whether an output was really modified after running a rule and tracking the fact that it is up to date separately from its timestamp. However, Ninja also stats all dependencies up front and will only restat files that are listed as outputs of rules with the 'restat' option enabled. Therefore an undeclared byproduct that does not exist at the start of the build will be considered missing and the build will fail even if other dependencies would cause the byproduct to be available before its dependents build. CMake works around this limitation by adding 'phony' build rules for custom command dependencies in the build tree that do not have any explicit specification of what produces them. This is not optimal because it prevents Ninja from reporting an error when an input to a rule really is missing. A better approach is to allow projects to explicitly specify the byproducts of their custom commands so that no phony rules are needed for them. In order to work with the non-Ninja generators, the byproducts must be known separately from the outputs. Add a new "BYPRODUCTS" option to the add_custom_command and add_custom_target commands to specify byproducts explicitly. Teach the Ninja generator to specify byproducts as outputs of the custom commands. In the case of POST_BUILD, PRE_LINK, and PRE_BUILD events on targets that link, the byproducts must be specified as outputs of the link rule that runs the commands. Activate 'restat' for such rules so that Ninja knows it needs to check the byproducts, but not for link rules that have no byproducts.
* | Ninja: Refactor restat to be a string internallyBrad King2014-11-141-1/+1
| | | | | | | | | | This will allow values other than "" and "1" to be generated in the rules.ninja file.

* Ninja: Skip generating empty phony rulesAdam Strzelecki2014-06-301-13/+19
| | | | | | | | | Ninja generator ensures that all custom commands being target dependencies are run before other source compilations. However in case there are no such dependencies it currently generates empty phony rules which clutter the build graph. Teach the Ninja generator to produce such rules only when necessary.
* Add OBJECT_FILE_DIR rule placeholder for compilation linesBrad King2014-06-051-0/+6
| | | | | | | | | Some compilers do not offer an option to specify the path to the object file, but rather only to the directory in which to place the object file. See issue 14876 for some examples. Add a new OBJECT_FILE_DIR placeholder to specify the directory containing the object file for the current compilation. This may differ from the main target OBJECT_DIR when the object corresponds to a source in a subdirectory.

| * Ninja: Fix deptype for Intel compiler on LinuxBrad King2014-05-091-2/+4
| | | | | | | | | | | | | | | | | | | | | | Since commit v3.0.0-rc1~305^2 (Ninja: deptype msvc for Intel's compiler on Windows, 2013-11-25) we used "deps = msvc" for the Intel compiler. This is correct only on Windows. On Linux we still want "deps = gcc". Fix the logic to use "deps = msvc" when the compiler id or the "simulate id" is "MSVC". This will preserve the behavior on Intel for Windows and fix the behavior on Intel for Linux. In the future this should be converted to a platform information module variable.
* | ninja: Factor out custom command order-only dependsBen Boeckel2014-05-071-14/+15

* | ninja: Factor out target-level order-only dependenciesBen Boeckel2014-05-071-5/+22

* | Ninja: Query custom commands once per target, not once per file.Stephen Kelly2014-04-051-7/+7

* | cmTarget: Make the source files depend on the config.Stephen Kelly2014-04-021-7/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Disallow the use of config-specific source files with the Visual Studio and Xcode generators. They don't have any way to represent the condition currently. Use the same common-config API in cmQtAutoGenerators. While it accepts config-specific files, it doesn't have to support multiple configurations yet. Loop over the configs in cmTargetTraceDependencies and cmGlobalGenerator::WriteSummary and consume all source files. Loop over the configs in cmComputeTargetDepends and compute the object library dependencies for each config.
* | cmTarget: Allow any generator expression in SOURCES property.Stephen Kelly2014-04-021-11/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove use of UseObjectLibraries from Makefile and Ninja generators. It is not needed now because those generators use GetExternalObjects which already contains the objects from object libraries. The VS10 generator calls both the UseObjectLibraries and the GetExternalObjects methods. Ensure that duplicates are not created by skipping objects from object libraries in handling of GetExternalObjects. Similarly, fix VS6, VS7 and Xcode object handling by skipping external objects from OBJECT_LIBRARY usage as appropriate. The error message in the BadSourceExpression1 test is now reported by the generator expression evaluator, so it has different text.
* | ninja: Add support for custom depfile formatsBen Boeckel2014-03-241-0/+5
| | | | | | | | | | | | | | | | Not everything that isn't MSVC is GCC. I have support for LDC's depfile format on its way upstream[1], but its future is uncertain. CMake should at least support this for future depfile formats. [1]https://github.com/martine/ninja/pull/721

| * | MSVC: Add properties to configure compiler PDB files (#14762)Brad King2014-02-261-0/+16
| |/ | | | | | | | | | | | | | | | | | | Since commit v2.8.12~437^2~2 (VS: Separate compiler and linker PDB files 2013-04-05) we no longer set /Fd with the PDB_NAME or PDB_OUTPUT_DIRECTORY properties. Those properties now exclusively handle linker PDB files. Since STATIC libraries do not link their compiler PDB file becomes more important. Add new target properties "COMPILE_PDB_NAME[_<CONFIG>]" and "COMPILE_PDB_OUTPUT_DIRECTORY[_<CONFIG>]" to specify the compiler PDB file location and pass the value to the MSVC /Fd option.

| * Replace <OBJECT_DIR> rule placeholder consistently (#14667)Brad King2014-01-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The <OBJECT_DIR> placeholder is supposed to be the base intermediate files directory for the current target. This is how it gets replaced during link line generation. However, during compile line generation we replace it with the directory containing the current object file which may be a subdirectory. Fix replacement of <OBJECT_DIR> in the generated compile lines to be the base intermediate files directory. This was expoxed by commit 42ba1b08 (VS: Separate compiler and linker PDB files, 2013-04-05) when we added a "/Fd<OBJECT_DIR>/" flag to the MSVC compile line in order to match the VS IDE default compiler program database location in the intermediate files directory. For source files in a subdirectory relative to the current target this caused the wrong location to be used for the compiler program database. This becomes particularly important when using precompiled headers. While at it, use the cmTarget::GetSupportDirectory method to compute the intermediate files directory for the current target instead of repeating the logic in a few places.
