D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.
Fixes#7082
Some compilers that act as linker drivers (dmd and ldc) need to split
arguments that GCC combines with , (ie, -Wl,-foo,bar -> -L=-foo -L=bar).
As such we need to detect that the previous argument contained -soname,
and not wrap that in a --start-group/--end-group
This modifies the shared library test to demonstrate the problem, with a
test case.
Fixes#6359
This is needed when mixing D and C code, as it's possible to end up
witha combination of linkers and compilres such that C produces pdb
files but D does not.
This allows the harness to apply the version correctly, putting it in the right
place, dropping the right amount of numbers, etc.
pdb taking a version allows it to be more easily copied from the
shared_lib type.
Static libraries don't have PDB files. A PDB that would previously end
up installed alongside a static library belonged in fact to the dynamic
version of the same library built at the same time.
This was because the former minstall.Installer implementation, when
installing a file target, also blindly copied any *.pdb file it found
whose filename was matching the target. So, for example installing
foo.dll and foo.a would also install two copies of foo.pdb into both
bin/ and lib/, which doesn't seem like the right thing to do - foo.pdb
should only get installed with foo.dll.
Change the code to store D properties as plain data. Only convert them
to compiler flags in the backend. This also means we can fully parse D
arguments without needing to know the compiler being used.
Of course D compilers have different flags to set some important
D-specific settings. This adds a simple method to change these flags in
a compiler-agnostic way in Meson.
This replaces the previous `unittest_args` method with a more generic
variant.
Actually, GDC supports shared libraries since version 6.2, but on Debian
there are still issues with that version due to the standard library not
being compiled with PIC.
Therefore, we make a very conservative assumption here and only enable
the tests for GDC >= 7.0
This allows us to disable the shared library test if the GNU D compiler
is detected.
This is useful, because gdc can not yet build proper shared libraries.
We also add a new test here which tests versioning of D shared
libraries.
D allows programmers to define their tests alongside the actual code in
a unittest scope[1].
When compiled with a special flag, the compiler will build a binary
containing the tests instead of the actual application.
This is a strightforward and easy way to run tests and works well with
Mesons test() command.
Since using just one flag name to enable unittest mode would be too
boring, compiler developers invented multiple ones.
Adding this helper method makes it easy for people writing Meson build
descriptions for D projects to enable unittestmode.
