# DESCRIPTION
# This file contains architecture independent  definitions and flags for the
# Diab tools (compiler, assembler, linker etc.)
#
#
# The following switches are used to compile C/C++ source. Most of these
# are being used to make the compiler lax regarding coding conventions
# used in many source files; however, some are being used to work around
# problems in specific source files.
#
#
# -Xintrinsic-mask=0x0     turn off generation of abs/fabs intrinsic; is
#                          this still needed?
#
