* Genex: Move TARGET_PROPERTY linked targets evaluation to endBrad King2019-07-211-35/+28

* cmGeneratorTarget: Refactor usage requirement genex evaluationBrad King2019-07-191-270/+209
| | | | | | | | | Evaluate usage requirement generator expressions fully before entering the processing loops. This allows us to evaluate and collect all entries up front and then have only one call to the loop over them. This also allows `AddInterfaceEntries` to immediately evaluate the generator expressions it synthesizes, which will enable later optimization.

| * | Swift: support SONAME on ELFish targetsSaleem Abdulrasool2019-07-181-2/+5
| | | | | | | | | | | | | | | | | | We should enable the soname to be setup for ELF shared libraries. Failure to do so generates binaries with incorrect names which prevents loading.

| * | Swift: add rules for static linkingSaleem Abdulrasool2019-07-181-0/+6
| | | | | | | | | | | | | | | | | | The Swift driver recently learnt how to generate static libraries using the `-static` flag. This enables us to generate proper static libraries with dependency tracking with Swift as well.
| * | Swift: Add library search paths for dependenciesSaleem Abdulrasool2019-07-181-7/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building Swift executables and libraries which import a module, an implicit link will be added by the driver. Because this links by name rather than path, the library search path needs to be provided to indicate where to find the library. For all local dependencies, add the library paths for the targets when linking. This ensures that you can link against local libraries without explicitly setting a library path. Fixes: #19304
| * | Support per-language library link flagsSaleem Abdulrasool2019-07-182-4/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the behaviour of the generators to use a per-language library search path flag. This is needed for multi-language projects with different compilers (e.g. cl + gfortran). Since the adjusted variable has been part of the user settings, we control this based on a policy.

| * | AIX: Do not enable runtime linking by default anymoreBrad King2019-07-173-14/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've long created shared objects on AIX using the linker's `-G` option (also offered by the XL front-end). The `-G` option implies `-brtl` and enables runtime linking. This has been largely unnecessary because we provide all dependencies on the link line and both XL and GNU compilers offer builtin behavior to export symbols. Since commit 0f150b69d3 (AIX: Explicitly compute shared object exports for both XL and GNU, 2019-07-11) we compute exports explicitly and consistently. Therefore runtime linking is no longer necessary for shared objects. We've also long created executables on AIX using the linker's `-brtl` option to enable runtime linking in case they load plugins at runtime. Since commit 9f5c2040bf (AIX: Explicitly compute executable exports for both XL and GNU, 2019-07-12) and commit 2fa920c0cd (AIX: Create import library for executables with exports, 2019-07-16) we now provide the linker enough information to fully resolve symbols in plugins up front. Therefore runtime linking is no longer necessary for executables. Drop use of `-G` for creating shared objects and use the XL `-qmkshrobj` and GCC `-shared` options instead. Both invoke the linker with the `-bM:SRE -bnoentry` options to create a shared object without runtime linking enabled. Also drop use of `-brtl` for creating executables. Issue: #19163

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On AIX, plugins meant to be loaded into executables via `dlopen` must be linked with access to a list of symbols exported from the executable in order to use them (when not using runtime linking). The AIX linker supports specifying this list as an "import file" passed on the command line either via the `-bI:...` option or (with a leading `#! .` line) as a normal input file like any other library file. The linker import file plays the same role on AIX as import libraries do on Windows. Teach CMake to enable its import library abstraction on AIX for executables with the `ENABLE_EXPORTS` target property set. Teach our internal `ExportImportList` script to optionally generate a leading `#! .` line at the top of the generated export/import list. Update our rule for linking an executable with exports to generate a public-facing "import library" implemented as an AIX linker import file. With this approach, our existing infrastructure for handling import libraries on Windows will now work for AIX linker import files too: * Plugins that link to their executable's symbols will be automatically linked using the import file on the command line. * The executable's import file will be (optionally) installed and exported for use in linking externally-built plugins. This will allow executables and their plugins to build even if we later turn off runtime linking. Issue: #19163

| * | | | | AIX: Explicitly compute executable exports for both XL and GNUBrad King2019-07-158-9/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On AIX, symbols in executables must be exported in order to be visible to modules (plugins) they load via `dlopen`. Prior to policy `CMP0065`, CMake linked all executables with flags to export symbols, but the NEW behavior for that policy is to do so only for executables that have the `ENABLE_EXPORTS` target property set. In both cases, CMake has always used the AIX linker option `-bexpall` option to export symbols from executables. This has worked fairly well with the XL compiler, but with the GNU compiler it works only for C ABI symbols. The reason is that `-bexpall` does not export symbols starting in `_` but the GNU C++ ABI mangles all symbols with a leading `_`. Therefore we have only supported C ABI plugins with the GNU compiler on AIX. Some projects have tried to work around this by replacing `-bexpall` with `-bexpfull`, but the latter often exports symbols that we do not want exported. Avoid using `-bexpall` for executables by instead using by our own internal `ExportImportList` script to compute symbol export lists from the object files to be linked into an executable. Pass the explicitly computed export list to the AIX linker's `-bE:...` option. We already do this for shared object exports. Issue: #19163
| * | | | | AIX: Explicitly compute shared object exports for both XL and GNUBrad King2019-07-153-20/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On AIX, symbols in shared objects must be exported in order to be visible to dependents (similar to Windows). The AIX linker provides a `-bE:...` option to specify a file listing symbols to be exported. Compilers offer some features to help: * When the XL compiler is invoked with its `-qmkshrobj`/`-G` options for creating shared objects (without/with runtime linking), it recognizes when no explicit `-bE:...` linker option is specified and runs a `CreateExportList` tool provided with the compiler to compute one from the object files. Since commit d468a2c2cb (XL: Avoid copying archives into shared libraries that link them, 2011-04-07, v2.8.5~153^2) CMake runs `CreateExportList` explicitly to ensure it only looks at the object files and not any library files. * When the GNU compiler is invoked with its `-shared` option for creating shared objects, its internal `collect2` tool recognizes when no explicit `-bE:...` linker option is specified and computes one itself from the object files. However, it sometimes includes extra symbols such as `.__init_aix_libgcc_cxa_atexit`. Introduce our own internal `ExportImportList` script to compute symbol export lists from object files. Use a basic implementation for now: it can be extended as needed later. Update our shared library creation rules to run the script explicitly for both the XL and GNU compilers. Issue: #19163

Since the latter commit we initialize the `CMAKE_{SHARED,MODULE}_LINKER_FLAGS` to use the `-brtl` linker flag. This is unnecessary because we already use the `-G` linker flag which implies `-brtl`. The latter commit also moved `-brtl` to `CMAKE_EXE_LINKER_FLAGS` from flags that were always included in executable link lines with CMP0065 OLD behavior and are not part of the change intended by CMP0065. Leave this for now as we've always enabled runtime linking for executables (and implicitly done so via -G for shared libraries and modules). Issue: #13997 Issue: #19163
