# DESCRIPTION
|
|
# This file contains definitions and flags for the gnu tools
|
|
# (compiler, assembler, linker etc.) to build for a generic
|
|
# PowerPC with PPC60x hardware floating point.
|
|
# If building for a specific processor (as a variant),
|
|
# defs.ppc will set its type number into PPC32VARIANT.
