In QEMU a single set of source files is built against many different
configurations in order to generate many executable. Each executable
includes a different but overlapping subset of the source files; some
of the files are compiled separately for each output, others are
compiled just once.
Using Makefiles, this is achieved with a complicated mechanism involving
a combination of non-recursive and recursive make; Meson can do better,
but because there are hundreds of such conditional rules, it's important
to keep meson.build files brief and easy to follow. Therefore, this
commit adds a new module to satisfy this use case while preserving
Meson's declarative nature.
Configurations are mapped to a configuration_data object, and a new
"source set" object is used to store all the rules, and then retrieve
the desired set of sources together with their dependencies.
The test case shows how extract_objects can be used to satisfy both
cases, i.e. when the object files are shared across targets and when
they have to be separate. In the real-world case, a project would use
two source set objects for the two cases and then do
"executable(..., sources: ... , objects: ...)". The next commit
adds such an example.
Apparently we have no tests for this because this is broken pretty
badly. This extends the basic test to actually check for the correct
free-form argument and thus test this.
This test currently assumes that the fortran compiler is gfotran, and
if we're not using g++ it skips. This patch changes it to skip if the
fotran compiler and the c++ compiler aren't the same family. This still
may skip in some cases it shouldn't (clang and gfort probably work fine
on windows), but it does enable ifort + ICL. Which is hte point.
It turns out there's a bug in creating a sub dependency out of threads
in that we pass all of the kwargs from the parent to the
ThreadDependency instance. This demonstrates the bug.
For consistency, it can be useful to have an explicit empty test suite list
for a test:
test('test-name', binary, suite: [])
This currently passes meson but fails when running meson tests:

* docs: document unrecognized escape sequence behaviour [skip ci]
Document that unrecognized escape sequence behaviour is like python, not
C.
* Don't try to decode invalid hex escape sequences
Don't try to decode escape sequences which should contain a sequence of
hex digits, but don't, throwing a python exception. These will treated
literally instead.
* Extend test case to cover invalid escape sequences
If the detected gpgme version is recent enough to match the version in
which upstream pkg-config files were added, assert that the default
found dependency is of the pkgconfig type.
Warn when someone tries to use append() or prepend() on an env var
which already has an operation set on it. People seem to think that
multiple append/prepend operations stack, but they don't.
Closes https://github.com/mesonbuild/meson/issues/5087
This creates a new command line option to store pkg_config_path into,
and store the environment variable into that option. Currently this
works like the environment variable, for both cross and native targets.
