Commit ff4a17dbef modified the version
requirements wrongly. AppleClangC should be the one with higher version
numbers. Exchange them to fix the check.
compiler.get_supported_arguments reports success for certain unsupported
flags when using the gnu C/ObjC, C++/ObjC++ compilers. This fix reads
the stderr on the has_arguments check to ensure the arguments really are
supported and not valid for the language selection
Now that the linkers are split out of the compilers this enum is
only used to know what platform we're compiling for. Which is
what the MachineInfo class is for
Instead of the DynamicLinker returning a hardcoded value like
`-Wl,-foo`, it now is passed a value that could be '-Wl,', or could be
something '-Xlinker='
This makes a few things cleaner, and will make it possible to fix using
clang (not clang-cl) on windows, where it invokes either link.exe or
lld-link.exe instead of a gnu-ld compatible linker.
Ifort can generate dependency information (.d files), it just does it
differently than GNU compilers do. This also fixes a bug caused by
adding the dependency generation commands to the GNULike class later in
this series.
We support 3 D compilers, DMD, LDC, and GDC. DMD is the reference
compiler, and LDC attempts to largely mirror it's command line usage.
GDC does not, it instead acts like GCC (which makes sense). The current
abstraction puts DMD behavior in the base D compiler and then overrides
then in the GnuDCompiler class.
This is messy, but it becomes more problematic when splitting the linker
and compiler abstractions apart.
I've opted to instead split the DCompiler class into two separate
classes. The DCompiler implements core D functinoality, and
DmdLikeCompilerMixin, which implements the DMD and LDC command line
arguments. I've then mxed that into the DmdDCompiler and LLVMDCompiler
classes, and mixed the GnuCompiler into the GnuDCompiler class to get
Gnu command line behavior.
To make Fortran tests useful on Windows, the library_type should default to static,
unless needed to specifically test shared. Shared Fortran libs on Windows for
non-Gfortran compilers is fragile requiring proprietary code syntax.
* PGI C++ PCH enable
PGI compilers support precompiled headers for C++ only.
The common/13 pch test passes if run manually with no spaces in the build path.
However, since Meson run_project_tests.py makes temporary build directories
with spaces in each tests, PGI --pch_dir can't handle this and fails.
So we skip the test for PGI despite it working for usual case with no-spaces
in build dir.
Note: it's fine to have spaces in full path for sourcedir, just no spaces in
relative path to builddir.

There are two problems, one is that it assumes -flto is the argument
to do LTO/WPO, which isn't true of ICC and MSVC (and presumably)
others. It's also incorrect because it assumes that the compiler and
linker will always be the same, which isn't necessarily true. You
could combine GCC with Apple's linker, or clang with link.exe, which
use different arguments.
