This is the result of automated script (0.9.0) conversion:
oe-core/scripts/contrib/convert-overrides.py .
converting the metadata to use ":" as the override character instead of "_".

Default Link Time Optimization flags should contain Os option along with
flto and ffat-lto-objects flags to inline with the regular esw default
compiler flags.

Based on performance measurements as well as recent presentations at ELC
it is believed the correct default should always be -O2. -Os should only
be selectively used per module instead of default.

Both xilinx-standalone (w/ lto) and xilinx-standalone-nolto need to use
a common set of system settings. A few settings were missed in the
merge of the decoupling work. Move these to the common settings file.

Instead of using ESW_CFLAGS for the optimization level, fall back to the
default Yocto Project method of 'FULL_OPTIMIZATION' and
'SELECTED_OPTIMIZATION'.
FULL_OPTIMIZATION is moved from -O2 to -Os, the other components retain
the default Yocto Project setitng of '-pipe ${DEBUG_FLAGS}'.

Some builds may require LTO, while others do not want it. The LTO components
are only enabled when using the esw.bbclass and the xilinx-standalone distro.
A second xilinx-standalone-nolto was added specifically to provide a default
where LTO was disabled.

When running gcc built for xilinx-standalone using mingw sdk machine, it
would throw an error saying the winpthread dll was missing. this is
because in tclibc-newlib, TOOLCHAIN_HOST_TASK was being overwritten and
omitting nativesdk-packagegroup-sdk-host which pulled in the appropriate
package nativesdk-mingw-w64-winpthreads. Manually adding the following
to TOOLCHAIN_HOST_TASK to bypass this issue:
nativesdk-qemu-xilinx

Distro Changes:
When building a multilib, we need to disable configsite cache. Otherwise
the system will fail to generate the SDK as there are no configsite entries
due to newlib based multilibs.
Recipe Changes:
gcc - globally disable multilib configuration
- Disable Linux specific configurations (EXTRACONFFUNCS)
gcc-cross-canadian - enable multilib on a recipe specific basis
libgcc - add a noop override to do_multilib_install to avoid Linux specific
multilib processing
newlib - arm/v6+m/nofp and arm/v8-m.base/nofp do not have newlib trap
implementations. libgloss contains these, workaround by
disabling builtin trap syscall handler.
- misc workarounds for multilib installs
libgloss - Allow MLPREFIX for newlib dependencies
meta-toolchain - adjust to install only the items we want/need
packagegroup-newlib-standalone-sdk-target - new pkggroup for the
custom baremetal SDK to select the right set of packages

dependencies
For the cross canadian toolchain we need to have both the libc.a and libgloss.a.
We add them to the LIBC_DEPENDENCIES which are wired in core to be added
to the sdk via the TOOLCHAIN_TARGET_TASK variable

components
This layer is meant to augment Yocto/OE functionality to provide a
toolchain to build standalone components for Xilinx architectures.
