Adds support for LTO on macOS and Android. We don't have much experience
with LTO on these platforms so for now we keep it disabled by default
even when `production=yes` is set.
Similarly for iOS where we ship object files for the user to link in
Xcode so LTO makes builds extremely slow to link.
`production=yes` defaults to full LTO.
ThinLTO is much faster for LLVM-based compilers but seems to produce
bigger binaries (at least for the Web platform).
Fixes a crash due to an Xlib error, as well as ensures that Godot
holds the correct size of the window after window modes have been
applied, before exiting the DisplayServerX11 constructor. This ensures
the bootsplash will be displayed with the correct dimensions.
Fixes#65320
The DisplayServerX11 constructor processes pending events shortly
after constructing the main window. However, it discards pending events
on the event queue that it is not interested in. This results in these
events never making it to the main events thread and as a result are
never processed. We need to save the events we don't handle in
DisplayServerX11 so that they can be resent for later handling by the
events thread.
Attempts to construct an X11 window in an initial state of
minimized/maximized would fail due to the window being unmapped.
We simply check for failed mode changes during an unmap and reapply
them if necessary.
Attempts to set a Godot window to fullscreen prior to the window being
mapped would silently fail. This commit uses
_window_fullscreen_check to test if a window had been set to fullscreen
while unmapped, and if so, resets it to fullscreen once the window has
been successfully mapped.
Fixes#54065
The new option is `linker` and lets the user specify the argument to
the`-fuse_ld=` linker flag directly. The supported options are:
- `default`: No change, typically uses GNU ld (bfd) unless the user or
distro picked a different default `/usr/bin/ld`.
- `bfd`: GNU ld from binutils
- `gold`: GNU gold from binutils
- `lld`: lld from LLVM
- `mold`: mold, an extremely fast modern linker, not (yet) intended for
use in production but great for development speed. Provided by distro
`mold` package or needs to be compiled from source and installed to
`/usr` otherwise.
Removes the `use_lld=yes` option, and make lld actually usable with GCC
too.
Not all the above are compatible or recommend for LTO, we recommend
using GNU ld with GCC LTO, or lld with LLVM ThinLTO.
Now the `linuxbsd` platform can be built headlessly (e.g. without X11
development libraries).
I also cleaned up some weird (old?) usages of the `env` variable which
seem to make no difference and are used nowhere else.
