Enables -Db_sanitize=undefined and company.
Also serves as a testcase for NVCC comma-shielding: Because the test-
case declares `b_sanitize=address,undefined`, the host GCC compiler
needs `-fsanitize=address,undefined`, but this stands a danger of being
split by NVCC when wrapped with `-Xcompiler=args,args`. Special,
already-existing comma-shielding codepaths activate to prevent this
splitting.
Closes#8394.
Currently we don't handle things correctly if we get a string we should
split, and the linker and needs compiler arguments. It would result in
two unsplit strings in a list, instead of the split arguments in a list
Fixes: #8348
Clang has a hand `-Wunused-command-line-argument` switch, which when
turned to an error, gets very grump about `-flto-jobs=0` being set in
the compiler arguments (although `-flto=` belongs there). We'll refactor
a bit to put that only in the link arguments.
GCC doesn't have this probably because, a) it doesn't have an equivalent
warning, and b) it uses `-flto=<$numthreads.
Fixes: #8347
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
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.
This commit performs some cleanup for the msvc and clang-cl arguments.
* "Disable Debug" (`/Od`) is no longer manually specified for optimization levels {`0`,`g`} (it is already the default for MSVC).
* "Run Time Checking" (`/RTC1`) removed from `debug` buildtype by default
* Clang-CL `debug` buildtype arguments now match MSVC arguments
* There is now no difference between `buildtype` flags and `debug` + `optimization` flags
Compiler tests, such as checking for atomics support, could fail
when compiling to WebAssembly multithreaded targets because the
compiler tests got compiled to 'output.wasm'.
Using the '.wasm' suffix in recent versions of emscripten engages
STANDALONE_WASM mode, which disables features that require a JS
runtime like shared memory.
This created false negatives on support of those features when
building a library to be linked into an executable that is not
in STANDALONE_WASM mode.
Changing these to 'output.o' will continue to produce WebAssembly
object files, but they will no longer be configured for standalone
runtime mode.
The /ZI flag adds in "Edit and Continue" debug information, which will
cause massive slowdown. It is not a flag that we should be adding by
default to debug builds.
/Zi will still be added.
This has a bunch of nice features. It obviously centralizes everything,
which is nice. It also means that env is only re-read at `meson --wipe`,
not `meson --reconfigure`. And it's going to allow more cleanups.
This is PEP8 convention for a const variable. Also, make the type
Mapping, which doesn't have mutation methods. This means mypy will warn
us if someone tries to change this.
This patches takes the options work to it's logical conclusion: A single
flat dictionary of OptionKey: UserOptions. This allows us to simplify a
large number of cases, as we don't need to check if an option is in this
dict or that one (or any of 5 or 6, actually).
I would have prefered to do these seperatately, but they are combined in
some cases, so it was much easier to convert them together.
this eliminates the builtins_per_machine dict, as it's duplicated with
the OptionKey's machine parameter.
Adds TemporaryDirectoryWinProof which calls windows_proof_rmtree() on
error.
Use instead of hacky error handling (which might shadow other OSError)
in Compiler.compile().
Since the current approach of demoting to the nearest C standard *might*
work, but might not. For projects like Glib that detect which standard
is used and fall back this is fine. For projects like libdrm that only
work with gnu standards, this wont. We're nog tusing a warning because
this shouldn't be fatal if --meson-fatal-warnings is used. Also demote a
similar message in IntelCl from warning to log.
And then update the choices in each leaf class. This way we don't end up
with another case where we implicitly allow an invalid standard to be
set on a compiler that doesn't have a 'std' setting currently.
As far as I can Tell, rust just handles this for us (it's always worked
with no special arguments from us). However, since we're going to add
support for base options for rust, we need to add the method.
