* depenencies/llvm: Handle llvm-config --shared-mode failing
Fixes: #7371Fixes: #7878
* test cases/llvm: Refactor to use test.json
Instead of trying to cover everything internally
has_header returns a tuple of (found: bool, cached: bool), so `if
has_header` will always return true because the tuple is non-empty. We
need to check if the found value is true or not.
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
I've tested this on FreeBSD, and dragonfly's userland is close enough
I'm willing to call it good without testing. OpenBSD and NetBSD also
have a zlib in their base configurations, but I'm not confident enough
to enable those without testing.
This comes pre-installed, but currently we don't have a way to detect it
without relying on pkg-config or cmake. This is only valid with the
apple clang-based compilers, as they do some special magic to get
headers.
Currently PkgConfig takes language as a keyword parameter in position 3,
while the others take it as positional in position 2. Because most
dependencies don't actually set a language (they use C style linking),
using a positional argument makes more sense. ExtraFrameworkDependencies
is even more different, and duplicates some arguments from the base
ExternalDependency class.
For later changes I'm planning to make having all of the dependencies
use the same signature is really, really helpful.
This moves most of the execution code from the CMakeInterpreter
into CMakeExecutor. Also, CMakeTraceParser is now responsible
for determining the trace cmd arguments.
Some slight refactoring for the dependency classes and
I switched the elbrus compiler to the GnuLikeCompiler.
This is also the correct use according to the documentation
of GnuLikeCompiler.
Both scan-build and llvm-config need the same list of LLVM version
suffixes. It is better to keep the list at a common place instead of
having several copies in different files, which is likely to become
out-of-sync when the list is updated.
Cmake ignores shared vs dynamic linking, and always returns static. This
went unnoticed, but results in regresssions for mesa. We need to fix
cmake, but with 0.51.1 due out shortly switching the order provides a
quick fix to restore expected functionality seems acceptable.
Fixes#5568
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.
It turns out that llvm-config on windows can return such wonderful
output as `-LIBDIR:c:\\... c:\\abslute\\path\\to\\lib.lib`, which was
all fine and dandy when we were blindly passing it through, GCC/MinGW
ignored it and MSVC understood it meant `/LIBDIR:`; however, after we
added some code to validate linker arguments, and we have some code
before the validation that tries to remove posix style -L arguments,
resulting in IBDIR:..., which doesn't validate.
This patch fixes up the output of llvm-config so that -LIBDIR: is
replaced by the the link libdir argument of the compiler, via the
compiler/linker method for getting that.
Fixes#5419
Instad of having special casing of threads in the backends and
everywehre else, do what we did for openmp, create a real
dependency. Then make use of the fact that dependencies can now have
sub dependencies to add threads.
In Fedora 30 the llvm-config binary has the number of bits in the isa
added as a suffic to the name llvm-config-64 or llvm-config-32, and no
naked llvm-config binary is provided. This commit moves the list of
llvm-config binaries to the constructor so that we can modify the list
on a per-instance basis, and adds the new Feodra names.
Fixes#5059
Instead of trying to hardcode which versions of which OSes are
misconfiguring llvm-config, lets try to use a generic mechanism that
catches most of the broken cases.
If a dynamic lib is built but the tools are linked staticly
(LLVM_BUILD_LLVM_DYLIB=true and LLVM_LINK_LLVM_DYLIB=false) and you
don't enabled shared libs (LLVM_BUILD_SHARED_LIBS=false, which should be
false), then llvm-config will mistakenly return a each static library
with .(so|dll|dylib) appended, instead of -lLLVM-x.y.z. if
LLVM_LINK_LLVM_DYlIB is true this works fine. There's been a bug opened
in upstream since 2014 about this with no responses[1].
So, this patches looks at --shared-mode (which tells us whether
llvm-config was linked staticly or dynamicly), then if the shared-mode
is static it will check and see what it gets. If it gets valid results
then it will go with those, if it doesn't then it will try to build a
set of valid link arguments to link with libLLVM.(so|dll|dylib).

The versions of LLVM provided by brew have the same configuration problem that
dragonflyBSD and FreeBSD do, which means that they produce wrong results for
shared linking.
It appears that debian has changed their naming scheme. This might
require revisiting in the future to add llvm-config-7.0 if debian
decides to do that.
