So that every subclass doesn't have to reimplement it. Especially since
the Gnu implementation moved out of the CCompiler and into the
GnuLikeCompiler mixin
I made the mistake of always selecting the debug CRT for compiler
checks on Windows 4 years ago:
https://github.com/mesonbuild/meson/pull/543https://github.com/mesonbuild/meson/pull/614
The idea was to always build the tests with debugging enabled so that
the compiler doesn't optimize the tests away. But we stopped doing
that a while ago, and also the debug CRT has no relation to that.
We should select the CRT in the same way that we do for building
targets: based on the options.
On Windows ARM64, the debug CRT for ARM64 isn't always available, and
the release CRT is available only after installing the runtime
package. Without this, we will always try to pick the debug CRT even
when --buildtype=debugoptimized or release.
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
Currently this is done at the instance level, but we need it at the
class level to allow compiler "lang" args to be gotten early enough.
This patch also removes a couple of instance of branch/leaf classes
providing their own implementation that is identical to the Compiler
version.
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.
In most cases instead pass `for_machine`, the name of the relevant
machines (what compilers target, what targets run on, etc). This allows
us to use the cross code path in the native case, deduplicating the
code.
As one can see, environment got bigger as more information is kept
structured there, while ninjabackend got a smaller. Overall a few amount
of lines were added, but the hope is what's added is a lot simpler than
what's removed.
Also adds test case for shared library linking.
Closes#4912, at least on Linux. The future 0.50.0 does not yet claim to
support CUDA on systems other than Linux and backends other than Ninja.
