* Merge branch 'cxxmodules-build-export-different-directory-3.28' into ↵Ben Boeckel2024-05-029-0/+141

| * cmDyndepCollation: look at all `export(TARGETS)` callsBen Boeckel2024-05-029-0/+141
| | | | | | | | | | | | | | | | | | Previously, only `export()` calls in the same directory were noticed. Also add a test that exports in a different directory than the target itself resides in. Fixes: #25813
* | Tests/CXXModules: test exporting modules which include headersBen Boeckel2024-04-279-0/+176
|/ | | | | Test that headers that are part of the same target are available to modules in the target itself.
* Tests/CXXModules: add a test using `TARGET_OBJECTS` from modulesBen Boeckel2024-03-063-0/+41
| | | | See: #25732

* | cmExportFileGenerator: export link libraries as-isBen Boeckel2024-02-204-4/+4
| | | | | | | | | | | | | | This allows for transitive modules to work because `$<COMPILE_ONLY>`-wrapped dependencies do not end up in the `linked-target-dirs` collator property. Test suite exported property tests updated to account for the change.

| | | | | | | | | | | | | | Also update the `modules-json-file` test to account for the fact that `CXXModules.json` is not updated for timestamp-only rebuild triggers. See: #25511

* | cmDyndepCollation: collapse full path before looking upBen Boeckel2024-02-143-0/+30
|/ | | | | | | | `cmSourceFile::GetFullPath()` performs a `CollapseFullPath` before storing the path. Match this behavior when looking up paths from the source file set constructions. Fixes: #25614
* cxxmodules: compute link information for C++ module-consuming targetsMatheus Izvekov2024-01-143-0/+19
| | | | | | | | | Compute link information for all C++ targets which support modules instead of just those which may provide modules, as they may import modules as well. This captures `OBJECT` libraries using modules which otherwise do not have link steps. Fixes: #25592

| * Tests/CXXModules: enhance `internal-partitions` testBen Boeckel2023-12-054-1/+17
| | | | | | | | | | | | This test previously did not *require* that the internal partition be specified as a transitive usage because nothing from it was exposed. Plumb through usages such that the internal partitions are required.
| * Tests/CXXModules: import from an internal partitionBen Boeckel2023-12-053-2/+10
| | | | | | | | | | | | It is reported that MSVC doesn't support the `modname=` syntax in its `-reference modname=modname.ifc` for internal partitions. Add a test case.
* | cmCxxModuleMapper: Fix transitive requirements computationnamniav2023-12-0534-1/+382
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously CMake may generate incomplete transitive requirements in CMakeFiles/<target>.dir/CXXModules.json and therefore in module mapper for compiler, when source files were listed in CMakeList.txt in a certain order. This commit fixes the problem by correctly tracking unfinished transitive requirements computation of module units. There have been a simple circular test case whose circular dependency was reported by build system. Now with this correct implementation it's reported by CMake generating module mappers. Add two test cases for transitive requirements computation, one with adding source files in hardcoded order, and the other in randomized order. Fixes: #25465
* | Tests/CXXModules: add a test which scans a PCH-using sourceBen Boeckel2023-12-043-0/+22
|/ | | | This tests that PCH usage works with scanning logic.
* Clang-CXX: copy into the dyndep output on successBen Boeckel2023-11-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | When `clang-scan-deps` fails to scan (e.g., bad source syntax, junk flags, etc.), the redirection unconditionally updates the file. If this fails, the `.ddi` file timestamp is updated. If the state is then reverted (e.g., the command line returns to the state of the last successful build), the updated file is not useful, but `ninja` does not rerun because: - the command hash matches the last successful run - the output file is newer than its inputs However, since the `.ddi` file has been updated with bogus contents from a failed scan, collation fails as the `rules` array is empty (or incomplete from a batch scan). If `clang-scan-deps` were properly aware of its output file, it could use this to not write the file if any inner scan fails. Requested in https://github.com/llvm/llvm-project/issues/72875. See: https://github.com/llvm/llvm-project/issues/72875 Fixes: #25429
* cmNinjaTargetGenerator: do not order-depend on C++ module sourcesBen Boeckel2023-10-205-0/+52
| | | | | | | | | C++ module sources should not be included by any other TUs, so their presence cannot matter for order-only dependencies of the entire target. Exclude them. Update CMP0154 to take this into consideration and add tests to the `CXXModules` suite (which already deals with module support detection).
* cxxmodules: include `INCLUDES DESTINATION` directoriesBen Boeckel2023-10-166-4/+29
| | | | | | | These paths are added outside the normal property management mechanisms. Shuttle the value to the C++ module export as needed. Fixes: #25289
* Tests/RunCMake/CXXModules: remove experimental settingsBen Boeckel2023-10-072-4/+0
| | | | | Logical conflicts between the topic that introduced the tests and the removal of the experimental flag completely.
* cxxmodules: scan C++ sources for imports by defaultBen Boeckel2023-10-0238-38/+38
| | | | | Existing projects are not using C++ modules in their sources, so introduce policy CMP0155 to enable scanning by default.
* Tests/RunCMake/CXXModules: remove rules file requirementBen Boeckel2023-10-021-12/+2
| | | | | Only Clang needs to disable extensions in order to work; other implementations work as-is.
* CXXModules: remove `EXPERIMENTAL` from C++ module variable namesBen Boeckel2023-10-021-2/+2
|
* cmExperimental: remove the flag for C++ modulesBen Boeckel2023-10-0246-190/+0

|
* cmExportFileGenerator: export private compile info for C++ modulesBen Boeckel2023-08-1712-0/+410
| | | | | | | | | When consuming exported targets which contain C++ modules, the consuming project must be able to recompile BMI files using the original target's flags. This is because a module source may use some private target usage requirement but not want to propagate it to consumers. To facilitate this, export the private information as necessary for consumers to be able to perform the BMI compilations.
* Tests/RunCMake/CXXModules: actually generate the source at build timeBen Boeckel2023-08-072-5/+9
