Add C2x option support.

Fix mapping of apple compilers in cmake
|
|
It's not enough to detect that the linker is ld64: gcc, icc, and vanilla
clang all use ld64 on macoOS. Instead we have to detect the class of the
compiler, and determine if it's an Apple Compiler or a vanilla one.
|
|
These are needed because in some cases we need to be able to know if
we're using vanilla clang or Apple's clang.

It's equivalent to copyfile + copystat with the same arguments.

- Exceptions raised during subproject setup were ignored.
- Allow c_stdlib in native file, was already half supported.
- Eliminate usage of subproject variable name by overriding
'<lang>_stdlib' dependency name.

Look for group-able flags with a single regex match, since we are already using
regexes for .so files. Also weed out flags other than -isystem very quickly
with a single startswith call.
On a QEMU build, the time spent in to_native goes from 2.279s to 1.322s.
|
|
The lambda in NinjaBuildElement.write is quite expensive, totalling 0.3s
just to do a couple function calls. Since it is used just once, simply
inline it.
On a QEMU build, the total time spent in write from this series goes from
5.321s to 3.238s, though part of it can be attributed to previous patches.
|
|
Optimize the regular expression so that the variable expansion part
always ends up in group 1, and the trailer after the variable is discarded
in the same match. Do not use re.sub to remove braces, and do not bother
building the expanded command, just adjust the estimated length on the fly.
functools.reduce is extremely slow, so I am keeping ' '.join(chunk).
On a QEMU build the time spend in the function goes from 1.072s to 0.757s.

extract_objects is repeatedly looking up files in self.sources, which is a list.
Convert it to a set beforehand so that the lookup is O(1).
On a QEMU build, the time spent in extract_objects goes from 3.292s to 0.431s.

Most files are going to be looked up into a set or dictionary. Precompute
the hash so that we only need to do so once and we can also use it to
quickly weed out unequal objects.
On a QEMU build, the time spent in __eq__ and __hash goes respectively
from 3.110s to 2.162s and from 0.648s to 0.299s. Even larger gains are
obtained by the next patch.
|
|
Use regular expressions to quickly weed out strings that require quoting
On a QEMU build the time spent in ninja_quote goes from 1.978s to 1.281s,
with str.replace being kicked completely out of the profile.
|
|
pre_flush_set and post_flush_set are almost always empty, so we can use
extend() instead of a for...in loop to add the previous elements of
self._container.
We can also skip the conversion from deque to list since pre_flush is
always appended on the right side.
On a QEMU build the time spent in flush_pre_post goes from 1.4 to 0.5
seconds.

|
If we can't find a static library, we should say that. It's confusing
otherwise.
|
|
Without the parenthesis, the command evaluates to `[]` if
`use_llvm_cov` is `False`.
Also fix tests to actually check whether or not coverage reports are
generated.

Meson and CMake compiler ids are different. This commit adds a mapping
from the meson list:
https://mesonbuild.com/Reference-tables.html#compiler-ids
to the CMake list:
https://cmake.org/cmake/help/latest/variable/CMAKE_LANG_COMPILER_ID.html
The mapping is not 1-1, and not all entries are mapped, so this is
a best-effort attempt. Fallback to GNU as before to try to limp along
and hope that the build files don't rely on an accurate compiler ID.
|
|
Without this, MSVC and MSVC_VERSION won't be set by CMake during
platform detection, and the compiler will be an undefined mixture of
GNU and MSVC. In particular, find_package(opencv) will fail on Windows
when building with MSVC.

This is required to make `-include /path/to/custom/target.hpp`
work. This setup is used by wxWidgets and this PR is
required to use wxWidgets as a CMake subproject.

According to the specification:
https://testanything.org/tap-specification.html#skipping-tests
The harness should report the text after # SKIP\S*\s+ as a reason for
skipping.
(it's not exactly like the TODO directive, the phrasing/presentation of
the spec could be improved).

Fixes: #7495

The compilers_detect function is only used in the qt module, which
checks every time before using a specific compiler, if it is found.
e.g.
meson.build:10:6: ERROR: MOC sources specified and couldn't find moc-qt5, please check your qt5 installation
In fact, the current check means we never even hit this error to begin
with, because we previously died on the uninformative error:
meson.build:10:6: ERROR: Program(s) ['moc'] not found or not executable
which doesn't actually tell the user why this matters, and is all around
a waste of time.
Fixes #5582

cmake: resolve IMPORTED executables in custom commands (fixes #7509)

* mtest: TestResult.SKIP is not a failure
If some but not all tests in a run were skipped, then the overall result
is given by whether there were any failures among the non-skipped tests.

* Add test-cases for partially skipped TAP tests
issue7515.txt is the output of one of the real TAP tests in gjs, which
failed as a result of #7515. The version inline in meson.build is
a minimal reproducer.

The `debug` builtin option does not control whether or not the debug
CRT is used. Without this fix, when buildtype=debugoptimized or when
debug=true + b_vscrt=md, we will try to link to the debug libraries
found via cmake while linking with `/release`, which will cause a link
failure.
|

This is obviously wrong, since on Windows ':' is in the drive letter.
Causes us to call cmake with `-DCMAKE_PREFIX_PATH=c;\foo\bar`.

There is nothing to "warn" about, this is a completely routine
occurence. OTOH, when something is corrupted, we should warn. Keep
the red color and "WARNING:" prefix in that case.
Example output:
$ ninja -C build
Regenerating configuration from scratch: Build directory has been generated with Meson version 0.55.999, which is incompatible with current version 0.56.0.

I've been getting confused between them and similarly-named other
things, so I figured it was high time to clean this up.

Meson calls `path/to/clang++ --version` to guess which build toolchain the
user has picked to build the source code. For the Qualcomm LLVM toolchain,
the output have an unusual output as shown below:
```
clang version 8.0.12
Snapdragon LLVM ARM Compiler 8.0.12 (based on llvm.org 7.0+)
Target: arm-unknown-linux-gnueabi
Thread model: posix
Repository: (ssh://git-hexagon-aus.qualcomm.com:...)
InstalledDir: /pkg/qct/software/llvm/release/arm/8.0.12/bin
```
Another unusual pattern is the output of `path/to/ld.qcld --version`:
```
ARM Linker from Snapdragon LLVM ARM Compiler Version 8.0.12
ARM Linker based on LLVM version: 8.0
```
The Meson logic is modified accordingly so that Meson can correctly
determine toolchain as "LLVM aarch64 cross-compiler on GNU/Linux64 OS".
This is the expected output of
`meson --native-file native_file.ini --cross-file cross_file.ini build/aarch64-debug/`:
```
...
C++ compiler for the host machine: ... (clang 8.0.12 "clang version 8.0.12")
C++ linker for the host machine: ... ld.lld 8.0.12
...
```

This creates a full set of option in environment that mirror those in
coredata, this mirroring of the coredata structure is convenient because
lookups int env (such as when initializing compilers) becomes a straight
dict lookup, with no list iteration. It also means that all of the
command line and machine files are read and stored in the correct order
before they're ever accessed, simplifying the logic of using them.
|
|
This puts all of them together, in the next patch they'll be pulled back
out, but it's convenient to start that refactor by moving them all
there, then moving them into env as a whole.
