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.
Error example:
Code:
#include <locale.h>
int main () {
/* If it's not defined as a macro, try to use as a symbol */
#ifndef LC_MESSAGES
LC_MESSAGES;
#endif
}

cc1: some warnings being treated as errors
There is a pretty big error in here, trying to return a tuple
comperhension: (a for a in []) is not a tuple, it's a generator. This
has profound type annotations: generators don't support most tuple or
list methods, and they can only be iterated once. Beyond that tuples are
meant for heterogenous types, ie, position matters for types. I've
converted the output to a list in all cases.
The compilers module is rather large and confusing, with spaghetti
dependencies going every which way. I'm planning to start breaking out
the internal representations into a mixins submodule, for things that
shouldn't be required outside of the compilers module itself.
* correct handling of LDFLAGS in find_library and sanity_check on MSVC (fixes#3629)
The MSVC compiler requires all linker flags to be placed after the compiler flags, separated by a "/link" argument. This was already handled for regular linking commands, but not yet for the aforementioned special code paths.
* on MSVC, add /link separator between compiler and linker flags when it is missing
* avoid unnecessary /link argument
