Both Clang and GCC support using multiple threads for preforming link
time optimizaions, and they can now be configured using the
`-Db_lto_threads` option.
Fixes#7820
This new keyword argument makes it possible to run specific
test setups only on a subset of the tests. For example, to
mark some tests as slow and avoid running them by default:
add_test_setup('quick', exclude_suites: ['slow'], is_default: true)
add_test_setup('slow')
It will then be possible to run the slow tests with either
`meson test --setup slow` or `meson test --suite slow`.
This will be needed to exclude testsuites from test setups (which
are stored in the build data). While at it, since a chdir is
needed simplify a bit the loading of tests and benchmarks.
This commit fixes the test that asserts on whether the lchmod() function
should have been detected as available by Meson. It does so by assuming
that on Linux systems not using glibc, the function will be available.
- fix comment about lchmod on Linux: musl has implemented the function
correctly since 2013, so the assumption in the test wasn't correct.
Furthermore, musl doesn't use glibc's stub mechanism.
- fix include to receive __GLIBC__ definition: including almost any
header in glibc will end up defining __GLIBC__, since most headers
include <features.h>. The <gnu/libc-version.h> header was probably
chosen because of its name, but its actual purpose is defining functions
for checking glibc version at runtime (instead of what the binary was
built with), so it isn't necessary to use it. Since it is a completely
non standard header, including it makes the test suite fail on musl due
to not finding the header.
It is common, at least in GNOME projects, to have scripts that must be
run only in the final destination, to update system icon cache, etc.
Skipping them from Meson ensures we can properly log that they have not
been run instead of relying on such scripts to to it (they don't
always).
Add function to Build class to get targets of type BuildTarget
Update xcode backend to call get_build_targets when iterating over targets.
This resolves crash in xcode backend when using custom targets:
AttributeError: ‘CustomTarget’ object has no attribute ‘objects’
On Windows this would fail because of missing DLL:
```
mylib = library(...)
exe = executable(..., link_with: mylib)
meson.add_install_script(exe)
```
The reason is on Windows we cannot rely on rpath to find libraries from
build directory, they are searched in $PATH. We already have all that
mechanism in place for custom_target() using ExecutableSerialisation
class, so reuse it for install/dist/postconf scripts too.
This has bonus side effect to also use exe_wrapper for those scripts.
Fixes: #8187
It doesn't make sense to check for the presence of git every time we use
it, but short-circuit any attempt to use a wrap right from the get-go
because we are trying to be fancy with submodules.
If git is not installed, simply do not try to figure out whether the
wrap is a submodule that can potentially be checked out/updated for the
user. Just take it on faith that it isn't one.
Fixes#2623
ARM64EC is a new ARM64 ABI made by Microsoft. The ARM64EC binaries can be loaded in x64 processes on the latest Windows Insider Preview on ARM64, and they don't need to be emulated for the sake of performance.
To support the ARM64EC build target, a new conceptual arm64 cpu type 'arm64ec' is added. The cpu can be specified in cross files like below to generate msbuild solution/vcxproj files with platform set to ARM64EC.
[target_machine]
system = 'windows'
cpu_family = 'aarch64'
cpu = 'arm64ec'
endian = 'little'
Currently mesonlib does some import tricks to figure out whether it
needs to use windows or posix specific functions. This is a little
hacky, but works fine. However, the way the typing stubs are implemented
for the msvcrt and fnctl modules will cause mypy to fail on the other
platform, since the functions are not implemented.
To aleviate this (and for slightly cleaner design), I've split mesonlib
into a pacakge with three modules. A universal module contains all of
the platform agnositc code, a win32 module contains window specific
code, a posix module contains the posix specific code, and a platform
module contains no-op implementations. Then the package's __init__ file
imports all of the universal functions and all of the functions from the
approriate platform module, or the no-op versions as fallbacks. This
makes mypy happy, and avoids `if`ing all over the code to switch between
the platform specific code.
