as instructed in the python docs, you should not use PIPE here. This can
lead to deadlocks, with massive testsuite output. Which was the case for efl.
For now the output of the tests is redirected into the a temp file, the
content from there can then be used to fill the TestRun structure.
This fixes test running problems in efl.
Add Windows SDK tools to PATH (for rc). This requires INCLUDE to be set.
lld-link doesn't seem to default to searching the correct directories, so
LIB needs to be set.
The easiest way to get the correct setting of INLCUDE and LIB env vars seems
to be to import the VS env vars, then revert the PATH.
'test cases/common/123 llvm ir and assembly' requires ML/ML64 (masm) on
Windows. If we are using clang-cl, that might not be available, so skip
test in that case.
Use the compiler detector in detect_system_compiler(), rather than trying to
guess based on what it is the PATH (which could utterly fail e.g when CC env
var is set)
Note that this detection is only used by platform_fix_name() to interpret
installed_files.txt
AR wasn't reset in the environment, so this test could fail if more than one
language compiler was specified in the environment and the linker wasn't
'ar'
clang-cl does support '-Wmissing-include-dirs' (unlike msvc), but doesn't
(currently) support '/ZI' (which is used by the default 'debug' buildtype),
the presence of which will cause an 'unknown-argument' warning, which is
treated as an error with 'Werror'.
Adjust the default buildtype so this test can pass with clang-cl
Rewrite test common/100 manygen using get_argument_syntax(), so it
treats clang-cl as cl, can handle only clang-cl being available, and try
to make it a bit less convoluted.
It seems that clang-cl isn't quite compatible with cl in the way it handles
pch, and when the precompiled header is used, the pathname of the header is
needed, not just its filename.
This fixes test\common\13 pch with clang-cl
When invoked as clang-cl to compile, it doesn't emit cl-compatible D9002
warnings about unknown options, but fortunately also supports
-Werror-unknown-argument instead.
When invoked to link, and using LINK, it does emit cl-compatible LNK4044
warnings about unknown options.
Currently, ComplierHolder.determine_args() unconditionally adds the link
arguments to the commmand, even if we aren't linking, because it doesn't
have access to the mode (preprocess, compile, link) that
_get_compiler_check_args() will use.
This leads to command lines like:
'cl testfile.c /nologo /showIncludes /c /Fooutput.obj /Od kernel32.lib
user32.lib gdi32.lib winspool.lib shell32.lib ole32.lib oleaut32.lib
uuid.lib comdlg32.lib advapi32.lib'
which clang-cl considers invalid; MSVS cl accepts this, ignoring the
unneeded libraries
Change from passing extra_args down to _get_compiler_check_args(), to
passing down a callback to CompilerHolder.determine_args() (with a bound
kwargs argument), so it can consult mode and kwargs to determine the args to
use.
Accomodate clang-cl /showIncludes output in detect_vs_dep_prefix().
clang-cl outputs lines terminated with \n, not \r\n
v2:
should invoke the detected compiler, not hardcode 'cl'
Handle clang's cl or clang-cl being in PATH, or set in CC/CXX
Future work: checking the name of the executable here seems like a bad idea.
These compilers will fail to be detected if they are renamed.
v2:
Update compiler.get_argument_type() test
Fix comparisons of id inside CCompiler, backends and elsewhere
v3:
ClangClCPPCompiler should be a subclass of ClangClCCompier, as well
Future work: mocking in test_find_library_patterns() is effected, as we
now test for a subclass, rather than self.id in CCompiler.get_library_naming()
Some compilers try very had to pretend they're another compiler (ICC
pretends to be GCC and Linux and MacOS, and MSVC on windows), Clang
behaves much like GCC, but now also has clang-cl, which behaves like MSVC.
This method provides an easy way to determine whether testing for MSVC
like arguments `/w1234` or gcc like arguments `-Wfoo` are likely to
succeed, without having to check for dozens of compilers and the host
operating system, (as you would otherwise have to do with ICC).
As mentioned in #4407, if dependency('boost') fails, the error message
is 'Dependency "boost" not found, tried' (sic).
Similar to line 1451 above, suppress reporting the tried methods
returned by log_tried(), if the list is empty (as is the case with
boost)
This reduces the build time about 2 sec. The result itself is not hard
to calculate. However, persistent join calls with the same 2 strings are
not that usefull. This also caused about 600'000 calls to
get_target_dir, we are now down to 60'000 calls form this function to
get_target_dir.
Replace several checks against GCC_MINGW or (GCC_MINGW, GCC_CYGWIN) with
is_windows_compiler instead, so that clang and other gcc-like compilers
using MinGW work appropriately with vs_module_defs, c_winlibs, and
cpp_winlibs.
Fixes#4434.
It is a common idiom to look for a function or a specific type or
a header in various locations/libraries, and it can be confusing to
see the (seemingly) identical compiler check being done multiple
times.
Now we print the dependencies being used when a compiler check is run
Before:
Checking for function "fbGetDisplay": NO
Checking for type "GLeglImageOES": YES
Checking for function "asinh": YES
After:
Checking for function "fbGetDisplay" with dependency egl: NO
Checking for type "GLeglImageOES" with dependencies glesv2, gl: YES
Checking for function "asinh" with dependency -lm: YES
If a subproject is not required and fails during its configuration, the
parent project continues, but should not include any target or state set
by the failed subproject. This fix ninja still trying to build targets
generated by subprojects before they fail in their configuration.
The 'build' object is now per-interpreter instead of being global. Once
a subproject interpreter succeed, values from its 'build' object are
merged back into its parent 'build' object.
This allows using the imperfect profiles generated by multithreaded
programs. Without the argument, GCC fails to load them.
Clang just ignores the argument AFAICT.
