Douglas Royds via Openembedded-core bfd2ab3d67 icecc: Export ICECC_CC and friends via wrapper-script
By exporting ICECC_CC, ICECC_CXX, and ICECC_VERSION in a wrapper-script,
and putting this wrapper-script in the PATH, the Makefiles generated by CMake or
the autotools are able to function correctly outside of bitbake.
This provides a convenient developer workflow in which the
modify-compile-unittest cycle can happen directly in the ${B} directory.

The `rm -f $ICE_PATH/$compiler` line is transitional,
and can go at some later date (October 2020 or later, perhaps).

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
