The cl.exe from Visual Studio 2010 and earlier report '80x86', not
'x86', for the architecture that the compiler supports. So, we ought
to check for that as well to see whether we are building for 32-bit x86.

The out-of-source build syntax for gcovr 4.2 is different compared to
previous versions and therefore an update was needed. In researching the
most appropriate solution it was found that any gcovr version older than
3.3 always resulted in 0% coverage. Because of this, rather than adding
an additional layer of logic, some already existing logic was modified
to ensure correct syntax for the new version, while versions older than
3.3 are flagged as not supported.
Closes mesonbuild#5089.

From (almost) all points of view, the Xtensa toolchain can be treated as
a regular GCC toolchain.
This patch adds very basic support so that, at least, meson does not
fail when trying to use "xt-xcc" (which makes it possible to use it
without problems).

* coredata: store cross/native files in the same form they will be used
Currently they're forced to absolute paths when they're stored in the
coredata datastructure, then when they're loaded we de-absolute path
them to check if they're in the system wide directories. This doesn't
work at all, since the ninja backend will generat a dependency on a
file that is in the source directory unless the path was already given
as absolute. This results in builds being retriggereed forever due to
a non-existant file.
The right way to do this is to figure out whether the file is in the
build directory, is absolute, or is in one of the system paths at
creation time, and store that path as absolute. Then the code that
reads the file and the code that generates the dependencies in the
ninja backend just takes the computed list and there is no mismatch
between them.
Fixes #5257
* run_unittests: Add a test for correct native file storage
This tests the bug in #5257

When using clang as an objc/objc++ compiler, identify if it's a Windows
targeted compiler, so that GnuLikeCompiler::get_pic_args() doesn't use
'-fPIC', which clang considers an error for the Window target.
Future work: Factor out parsing the clang target string from the
detectors for various languages.

OpenBSD uses arm64 as identifier for the 64-bit ARM architecture.

Print "Found samurai-x.y" when samu is found instead of ninja,
and do not print "Found ninja-1.8-1.8" when NINJA points to
/usr/bin/ninja-1.8.

This can be useful to test a local ninja version (for example while developing
changes to ninja or samurai) without modifying the PATH.
The ninja binary that is detected is then hardcoded in the build.ninja
rules for scan-build and clean, so that it is always used until reconfiguration.

This function is used just once. It also seems all policy and no
mechanism (it raises, it calls the same function to do all the work
twice in a simple way). This makes it seem to be as a good candidate for
inlining.
`environment` and `coredata` are woefully intertwined and while this
change doesn't fix that, but at least it makes it easier to follow.

Just like --native-file, allow multiple --cross-file options. This is mostly
unifying the logic between cross_files and config_files.
|
|
Instead of hard-coding the fact that load_configs() searches for files under
meson/native, pass in the subdirectory allowing the cross-file code to use the
same logic.

We need to match the "clang --version" output on OpenBSD:
$ clang --version | head -1
OpenBSD clang version 7.0.1 (tags/RELEASE_701/final) (based on LLVM 7.0.1)

1. They (and the others) all use PerMachineDefaultable. It's not the
best class, but consistency come first. (It and all of them can be
improved accross the board later.)
2. They use `None` as the default argument so as not to mutate what's
effectively a global variables. (Thanks @dcbaker!)
3. They have a `fallback` field to centralize authority on when
environment variables should be consulted.

First of all, I'd like compilers and other modules that environment.py
currently imports to be able to take these without creating
hard-to-follow module cycles.
Second of all, environment.py's exact purpose seems a bit obscured.
Splitting the data types (and basic pure functions) from the more
complex logic that infers that data seems like a good way to separate
concerns.

It seems this was erroneously coppied in `54b6afa67`.

Just like the previous patch, but for cross files
Fixes #1433

This allows the person running configure (either a developer, user, or
distro maintainer) to keep a configuration of where various kinds of
files should end up.

Instead use coredata.compiler_options.<machine>. This brings the cross
and native code paths closer together, since both now use that.
Command line options are interpreted just as before, for backwards
compatibility. This does introduce some funny conditionals. In the
future, I'd like to change the interpretation of command line options so
- The logic is cross-agnostic, i.e. there are no conditions affected by
`is_cross_build()`.
- Compiler args for both the build and host machines can always be
controlled by the command line.
- Compiler args for both machines can always be controlled separately.

We used to look for the QMAKE env var in earlier versions of Meson,
start looking for it again.

First, I noticed there was a dangling use of now-removed cross_info in
the CMake lookup. No tests had caught this, but it means that CMake deps
were totally broken. [It also meant that CMake could not be specified
from a native file.]
In a previous of mine PR which removed cross_info, I overhauled finding
pkg-config a bit so that the native and cross paths were shared. I
noticed that the CMake code greatly resembled the pkg-config code, so I
set about fixing it to match.
I then realized I could refactor things further, separating caching,
finding alternatives, and validating them, while also making the
validations less duplicated. So I ended up changing pkg config lookup a
lot too (and CMake again, to keep matching).
Overall, I think I have the proper ideom for tool lookup now, repated in
two places. I think it would make sense next to share this logic between
these two, compilers, static linkers, and any other tool similarly
specifiable. Either the `BinaryTable` class in environment.py, or a new
class for `Compiler` and friends to subclass, would be good candidates
for this.

* Fixed spelling
* Merged the Buildoptions and Projectinfo interpreter
* Moved detect_compilers to Environment
* Added removed test case
* Split detect_compilers and moved even more code into Environment
* Moved set_default_options to coredata
* Small code simplification in mintro.run
* Move cmd_line_options back to `environment`
We don't actually wish to persist something this unstructured, so we
shouldn't make it a field on `coredata`. It would also be data
denormalization since the information we already store in coredata
depends on the CLI args.

On OpenBSD, the main PowerPC machine is known as macppc, while the processor
family is powerpc:
$ uname -{m,p}
macppc powerpc
$ echo 'import platform; print (platform.machine())' | python3
macppc
$ echo 'import platform; print (platform.processor())' | python3
powerpc
This allows for e.g. GLib configure to properly detect that cpu:
Build machine cpu family: ppc
Build machine cpu: macppc
While it failed before with: WARNING: Unknown CPU family 'macppc' <snip>

It appears that LIB/LINK default to the host architecture if they can't
guess it from the first object. With the MSVC toolchain, resource files
are (usually) compiled to an arch-neutral .res format. Always
explicitly provide a '/MACHINE:' argument to avoid it guessing
incorrectly when cross-compiling.
