612d6f29 Tests: Refactor GenerateExportHeader test code
ce76abb4 Tests: Add data symbols to GenerateExportHeader test
8f95b93b Tests: Add failure test for GenerateExportHeader
Refactor the library code used in the GenerateExportHeader test to use
an improved naming convention that more directly identifies what it
being tested, making use of namespaces to avoid possible symbol
collisions. This also eliminates duplicate cases such as `libshared()`
and `libshared_not_exported()` which had the same decoration, and adds
consistent pairings of <name>_EXPORT and <name>_DEPRECATED_EXPORT which
were missing previously. The data tests from the previous commit are
also added to `libstatic` and `libshared_and_static` for consistency.
Note that there are no exported members of exported classes, as these
are not allowed on Windows.
Add static data members and global variables to the GenerateExportHeader
shared library, testing that export decoration for these works in
addition to decoration of classes and free functions.
Modify notation of statements in the GenerateExportHeader test expected
to result in link errors. Modify script used to build the test to also
generate a suite of modified sources, each having exactly one of the
failing lines enabled, and to generate EXCLUDE_FROM_ALL executables for
the same. Modify RunCMake script used to drive the test to read the list
of such executables and try to build each of them, verifying that they
do in fact fail to build.
This will verify that the _NO_EXPORT macros are working as expected, and
will also catch errors like the one that commit 0cbaaf2d
(GenerateExportHeader: Fix add_compiler_export_flags regression,
2016-09-01) fixed.
When setting up the failure tests for GenerateExportHeader, check if the
compiler actually hides non-exported stuff. If not, the failure tests
won't fail, and will cause the overall test to fail. Since this
typically is only the case for very old compilers, simply skipping them
as opposed to trying to do something more fine grained seems reasonably
safe.
The `ARGC`/`ARGV#` variables in function scope hold the original
arguments with no ;-list flattening. Add a way for functions to
cleanly parse arguments that may contain `;`. This also avoids
extra copying of the arguments.

bdc679a8 VS15: Add Visual Studio 15 generator
a8936656 VS: Update v140 flag tables from VS 15 MSBuild files
21346d3f Features: Record features for VS 15 Preview 4
Call the generator "Visual Studio 15" without any year because the
preview version of VS 15 does not provide a year in the product name.
Copy cmGlobalVisualStudio14Generator to cmGlobalVisualStudio15Generator
and update version numbers accordingly. Add the VS15 enumeration value.
Note that we do not need to add a MSVC15 variable or v150 toolset
because Visual Studio 15 comes with an updated version of the v140
toolset and remains ABI-compatible.
Teach tests VSExternalInclude, RunCMake.GeneratorPlatform, and
RunCMake.GeneratorToolset to treat VS 15 as they do VS 10-14.
Closes: #16143
Since commit 14a8d61f (cmMakefile: Port nested error logic away from
cmExecutionStatus) we fail to continue processing function and macro
bodies after non-fatal errors. A non-fatal error should not stop
foreach loops, macro bodies, nested bodies, or the outer script.
Add a test covering these cases, and revert the change to fix them.
Also revert commit 2af853de (cmMakefile: Simplify IssueMessage
implementation) because the assertion it added (which was removed by the
above commit and is restored by reverting it) is incorrect. We do have
code paths that call cmMakefile::IssueMessage with an empty execution
stack, such as in CheckForUnusedVariables's LogUnused call.

When `$<LINK_ONLY:...>` is used outside of linking we may evaluate it
without a `dagChecker`. Do not dereference the NULL pointer and issue a
diagnostic instead.
Closes: #16287
Provide a way for custom commands to inform the ninja build tool about
their implicit dependencies. For now simply make use of the option an
error on other generators.

With the Makefile generator one can use `cd $subdir; make install` to build and
install targets associated with a given subdirectory. This is not possible to
do with the Ninja generator since there is only one `build.ninja` file at the
top of the build tree. However, we can approximate it by allowing one to run
`ninja $subdir/install` at the top of the tree to build the targets in the
corresponding subdirectory and install them.
This also makes sense for `test`, `package`, and other GLOBAL_TARGET targets.
It was already done for `all` by commit v3.6.0-rc1~240^2~2 (Ninja: Add
`$subdir/all` targets, 2016-03-11).

Teach Visual Studio generators to include object files from object
libraries in the list of objects whose symbols are to be exported.
The Makefile and Ninja generators already did this. Update the
test to cover this case.
Reported-by: Bertrand Bellenot <Bertrand.Bellenot@cern.ch>
Custom command dependencies are followed for each target's source files
and add their transitive closure to the corresponding target. This
means that when a custom command in one target has a dependency on a
custom command in another target, both will appear in the dependent
target's sources. For the Makefile, VS IDE, and Xcode generators this
is not a problem because each target gets its own independent build
system that is evaluated in target dependency order. By the time the
dependent target is built the custom command that belongs to one of its
dependencies will already have been brought up to date.
For the Ninja generator we need to generate a monolithic build system
covering all targets so we can have only one copy of a custom command.
This means that we need to reconcile the target-level ordering
dependencies from its appearance in multiple targets to include only the
least-dependent common set. This is done by computing the set
intersection of the dependencies of all the targets containing a custom
command. However, we previously included only the direct dependencies
so any target-level dependency not directly added to all targets into
which a custom command propagates was discarded.
Fix this by computing the transitive closure of dependencies for each
target and then intersecting those sets. That will get the common set
of dependencies. Also add a test to cover a case in which the
incorrectly dropped target ordering dependencies would fail.
Document these variables.
Change our convention for setting these variables from:
set(CMAKE_EXE_LINKER_FLAGS_INIT "...")
to
string(APPEND CMAKE_EXE_LINKER_FLAGS_INIT " ...")
so that any value previously set by a toolchain file will be used.
Document these variables.
Change our convention for setting these variables from:
set(CMAKE_C_FLAGS_INIT "...")
to
string(APPEND CMAKE_C_FLAGS_INIT " ...")
so that any value previously set by a toolchain file will be used.
Automate the conversion with:
sed -i 's/set *(\(CMAKE_\(C\|CXX\|Fortran\|RC\|ASM\|${[^}]\+}\)_FLAGS\(_[^_]\+\)\?_INIT \+"\)/string(APPEND \1 /' \
Modules/Compiler/*.cmake Modules/Platform/*.cmake
and follow up with some manual fixes (e.g. to cases that already
meant to append). Also revert the automated changes to contexts
that are not protected from running multiple times.
In the `try_compile` source file signature we propagate the caller's
value of `CMAKE_<LANG>_FLAGS` into the test project. Extend this to
propagate `CMAKE_<LANG>_FLAGS_<CONFIG>` too instead of always using the
default value in the test project. This will be useful, for example, to
allow the MSVC runtime library to be changed (e.g. `-MDd` => `-MTd`).
However, some projects may currently depend on this not being done,
so we need to activate the behavior using a policy.
This change was originally made by commit v3.6.0-rc1~160^2 (try_compile:
Honor CMAKE_<LANG>_FLAGS_<CONFIG> changes, 2016-04-11) but without the
policy and so had to be reverted during the 3.6 release candidate cycle.
Fixes#16174.
Revert commit v3.6.0-rc1~160^2 (try_compile: Honor
CMAKE_<LANG>_FLAGS_<CONFIG> changes, 2016-04-11). The behavior it
introduced can break projects that depend on the lack of such behavior.
We will have to introduce a policy or other mechanism to enable the
behavior in a compatible way. Simply revert it for now.
See issue #16174.
