# Handle old-style chip-specific toolchain names in the absence of
# a new-style toolchain specification, force the selection of a single
# toolchain and allow the selected toolchain to be overridden by a
# command-line selection.

# CortexM0. Since they are all GCC-based, we could almost
# certainly simplify this further.

#
# CROSSDEV The GNU toolchain triple (command prefix)
# ARCROSSDEV If required, an alternative prefix used when
# invoking ar and nm.
# ARCHCPUFLAGS CPU-specific flags selecting the instruction set
# options, etc.
# MAXOPTIMIZATION The maximum optimization level that results in
# reliable code generation.
