* Do not treat DEFINITIONS as a built-in directory propertyStephen Kelly2015-04-021-2/+13
| | | | | | | | Add policy CMP0059 to cover this change. The property has been deprecated since CMake 2.4 anyway. This will help clean up cmMakefile -- the DefineFlagsOrig member should not need to exist.

* Features: Define meaning for no language standard defaultBrad King2015-01-291-2/+44
| | | | | | | | | | | | Define an empty string in CMAKE_<LANG>_STANDARD_DEFAULT to mean that the toolchain has no notion of lanuage standard levels. In this case the <LANG>_STANDARD[_REQUIRED] properties will have no effect. Update the RunCMake.CompileFeatures test to exclude the LinkImplementationFeatureCycle test when there is no standard default. It can never fail because no use of specific features will adjust the CXX_STANDARD level required for any target since the standard levels have no meaning in this case.

| * | cmMakefile: store the number of last matches in a CMake varBen Boeckel2014-12-031-0/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | With PushScope and PopScope, keeping track of another bit of data for each scope isn't easy. Instead, store it as another CMake variable so it gets implicitly tracked along with everything else. This works in a revert of commit 7d674b5f0b28a610333644d417c2e8cb796cc9e4.

| | | | | | | | | | | | | | | | | | | | | | This reverts commit v3.1.0-rc1~557^2~2 (ClearMatches: Only clear matches which were actually set, 2014-03-12). The optimization did not track the match count in the same scope as the variables, allowing possible inconsistency.

* | | Track nested loop levels in CMake language with a stack of countersGregor Jasny2014-11-251-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It gets incremented while entering a loop block (e.g. foreach or while) and gets decremented when leaving the block. Because scope borders for example at function borders must be taken into account the counter is put into a stack. With every new scope an empty counter is pushed on the stack, when leaving the scope the original value is restored. This will allow easy querying if the break command is properly nested within a loop scope. Signed-off-by: Gregor Jasny <gjasny@googlemail.com>
* | | Add an option for explicit BYPRODUCTS of custom commands (#14963)Brad King2014-11-141-8/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The behaviors associated with implicit pulldown on variable lookup seriously conflict with the optimizations made in these commits. Basically, since values were copied upon variable lookup, not just on PARENT_SCOPE, coupled with PARENT_SCOPE's behavior based on whether the variable is in the current scope or not causes serious problems with not storing a value for every variable at every scope. The commit changed behavior of the following example, among other cases: function(test_set) set(blah "value2") message("before PARENT_SCOPE blah=${blah}") set(blah ${blah} PARENT_SCOPE) message("after PARENT_SCOPE blah=${blah}") endfunction() set(blah value1) test_set() message("in parent scope, blah=${blah}") Reported-by: Alex Merry <alex.merry@kde.org> Reported-by: Ben Cooksley <bcooksley@kde.org>
