db26871210 SCons: Add production=yes option to use production defaults
This is meant for users making custom builds to match the options used on
optimized, official builds.

This enables, on the platforms which support them:
- `use_static_cpp=yes` (portable binaries for Linux and Windows)
- `use_lto=yes` (link time optimizations - note: requires a lot of RAM!)
- `debug_symbols=no` (no debug symbols, smaller binaries)

Also abort when using MSVC with `production=yes`, as:
- It cannot optimize the GDScript VM like GCC or Clang do, leading to
  significant performance drops.
- Its LTO support is unreliable, at least used to trigger crashes last
  we tried it extensively.

All options can still be overridden if specified, and the `dev=yes` option
was changed to also support overrides.

SCons: Add only selected platform's opts to env
Otherwise we can get situations where platform-specific opts with the same name
can override each other depending on the order at which platforms are parsed,
as was the case with `use_static_cpp` in Linux/Windows.

Fixes #44304.

This also has the added benefit that the `scons --help` output will now only
include the options which are relevant for the selected (or detected) platform.

SCons: Remove unnecessary $LINK overrides
As of SCons 4.0.1, the default value for $LINK is $SMARTLINK, which itself
is a function that will use $CXX as linker for C++:

https://github.com/SCons/scons/blob/4.0.1/SCons/Tool/link.py#L327-L328
https://github.com/SCons/scons/blob/4.0.1/SCons/Tool/link.py#L54-L76

So we don't need to manually specify the same value as $CXX for $LINK.

OSX: Fix linking with osxcross for arm64
For some reason the `-target` option on the `LINKFLAGS` was causing a weird
issue where osxcross' clang wrapper would attempt using the system `/bin/ld`
instead of the osxcross version (which is Apple's `ld64`).

The error message would be:
```
/bin/ld: unrecognized option '-dynamic'
```

Also removed from `CCFLAGS` for consistency, it seems to work fine with only
`-mmacosx-version-min`.

Remove debug_symbols=full in favor of debug_symbols=yes
`debug_symbols=yes` will now behave like `debug_symbols=full` did
before. The difference in compressed file sizes is not that large,
which means there isn't much point in having two different values.

This helps make the buildsystem easier to understand.

cd4e46ee65 SCons: Format buildsystem files with psf/black
Configured for a max line length of 120 characters.

psf/black is very opinionated and purposely doesn't leave much room for
configuration. The output is mostly OK so that should be fine for us,
but some things worth noting:

- Manually wrapped strings will be reflowed, so by using a line length
  of 120 for the sake of preserving readability for our long command
  calls, it also means that some manually wrapped strings are back on
  the same line and should be manually merged again.

- Code generators using string concatenation extensively look awful,
  since black puts each operand on a single line. We need to refactor
  these generators to use more pythonic string formatting, for which
  many options are available (`%`, `format` or f-strings).

- CI checks and a pre-commit hook will be added to ensure that future
  buildsystem changes are well-formatted.

1f6c9328dd Revert "Change LINKFLAGS to FRAMEWORKS which is supported since"
This reverts commit c924e83a64.

SCons `FRAMEWORKS` is, according to their latest docs, only supported
"On Mac OS X with gcc". While the "with gcc" part seems bogus, #36795
did introduce a link failure for our osxcross toolchain for compiling
macOS binaries from Linux. SCons probably fails to detect this as a
macOS target and does not use its `FRAMEWORKS` logic properly.

So using `LINKFLAGS` as we used to is the more portable solution.

a4801674c5 SCons: Bump required C++ standard to C++17
As per #36436, we now need C++17's guaranteed copy elision feature to
solve ambiguities in Variant.

Core developers discussed the idea to move from C++14 to C++17 as our
minimum required C++ standard, and all agreed. Note that this doesn't
mean that Godot is going to be written in "modern C++", but we'll use
modern features where they make sense to simplify our "C with classes"
codebase. Apart from new code written recently, most of the codebase
still has to be ported to use newer features where relevant.

Proper support for C++17 means that we need recent compiler versions:

 - GCC 7+
 - Clang 6+
 - VS 2017 15.7+

Additionally, C++17's `std::shared_mutex` (conditionally used by
`vk_mem_alloc.h` when C++17 support is enabled) is only available in
macOS 10.12+, so we increase our minimum supported version.

b0d41847ed SCons: Use CPPDEFINES instead of CPPFLAGS for pre-processor defines
It's the recommended way to set those, and is more portable
(automatically prepends -D for GCC/Clang and /D for MSVC).

We still use CPPFLAGS for some pre-processor flags which are not
defines.

This is a new singleton where camera sources such as webcams or cameras on a mobile phone can register themselves with the Server.
Other parts of Godot can interact with this to obtain images from the camera as textures.
This work includes additions to the Visual Server to use this functionality to present the camera image in the background. This is specifically targetted at AR applications.

c2a669a9f0 SCons: Review uses of CCFLAGS, CXXFLAGS and CPPFLAGS
Many contributors (me included) did not fully understand what CCFLAGS,
CXXFLAGS and CPPFLAGS refer to exactly, and were thus not using them
in the way they are intended to be.

As per the SCons manual: https://www.scons.org/doc/HTML/scons-user/apa.html

- CCFLAGS: General options that are passed to the C and C++ compilers.
- CFLAGS: General options that are passed to the C compiler (C only;
  not C++).
- CXXFLAGS: General options that are passed to the C++ compiler. By
  default, this includes the value of $CCFLAGS, so that setting
  $CCFLAGS affects both C and C++ compilation.
- CPPFLAGS: User-specified C preprocessor options. These will be
  included in any command that uses the C preprocessor, including not
  just compilation of C and C++ source files [...], but also [...]
  Fortran [...] and [...] assembly language source file[s].

TL;DR: Compiler options go to CCFLAGS, unless they must be restricted
to either C (CFLAGS) or C++ (CXXFLAGS). Preprocessor defines go to
CPPFLAGS.

e5b335d367 Don't use -ffast-math or other unsafe math optimizations
Godot supports many different compilers and for production releases we
have to support 3 currently: GCC8, Clang6, and MSVC2017. These compilers
all do slightly different things with -ffast-math and it is causing
issues now. See #24841, #24540, #10758, #10070. And probably other
complaints about physics differences between release and release_debug
builds.

I've done some performance comparisons on Linux x86_64. All tests are
ran 20 times.

this pr    12.01  12.62  0.17    12.26  (97%)

I have also looked at FPS numbers for tps-demo, 3d platformer, 2d
platformer, and sponza and could not find any measurable difference.

I believe that given the issues and oft-reported (physics) glitches on
release builds I believe that the couple of percent of tight-loop
floating point performance regression is well worth it.

This fixes #24540 and fixes #24841

3624644630 Pass -isysroot to compiler / linker when doing a macOS build
Previously the compiler would use system headers located at
/System/Library/Frameworks, which could result in compilation failures
due to the headers not always being up-to-date in regards to the
latest installed macOS SDK headers that come with Xcode.

Fix the issue by passing the SDK path via the -isysroot option to the
compiler and linker invocations.

If no custom SDK path is given, the build system queries the SDK path
via xcrun --show-sdk-path, which returns something similar to

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/
 /Developer/SDKs/MacOSX.sdk/

Querying via xcrun is now also done for iphone (and simulator)
platforms as well.

Here is an example of a compilation failure message due to outdated
headers:

platform/osx/os_osx.mm:1421:41: error: use of undeclared identifier 'NSAppKitVersionNumber10_12'; did you mean 'NSAppKitVersionNumber'?
