| * Tests: Drop RunCMake workaround for AIX ld warnings about GNU atexitBrad King2019-07-151-2/+0
| | | | | | | | | | | | | | Drop the filtering added by commit e22c45d4c9 (Tests: Teach RunCMake to ignore AIX ld warnings about GNU atexit, 2018-02-28, v3.12.0-rc1~419^2~6). It is no longer needed now that we compute our own exports on AIX and do not get these warnings when using shared libraries.
| * 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
| * AIX: Drop redundant -brtl flagsBrad King2019-07-152-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We removed `-brtl` in commit bce7a2a3a5 (AIX: Do not use -brtl to create shared libraries, 2013-03-11, v2.8.11~103^2~1) but it was added again by commit f254276fc1 (AIX,HP-UX: Fix RPATH handling when CMP0065 is set to NEW, 2015-12-11, v3.4.2~4^2). 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
| * XL: De-duplicate shared object creation flagsBrad King2019-07-156-5/+2
| | | | | | | | | | | | The XL `-qmkshrobj` flag creates shared objects on all platforms. Move the flag out of the per-platform modules into the per-compiler module for XL.

| |/ | | | | | | | | | | | | In real projects the variable form should rarely be used because the decision to export symbols from an executable is very specific. Remove its main description, which duplicates the `ENABLE_EXPORTS` target property, and simply reference the property instead.

For example, the MS CSharp compiler uses UTF-16LE and a TI compiler uses UTF-16BE. Try each encoding. Fixes: #19459
