#
# The following options let you define non-default tools to use
#
# CUSTOM_LD is only used for the progressive linking of libraries.
# It is not used for linking the final target.
#
#CUSTOM_CC      = gcc
#CUSTOM_CXX     = g++
#CUSTOM_AS      = as
#CUSTOM_LD      = ld

#
# For using a cross-compile tool chain, the names of all
# binutils and compilers are typically prefixed by the
# target platform. Instead of defining CUSTOM_* variables
# individually for each tool, the prefix can be defined
# via the following variable.
#
ifeq ($(filter-out $(SPECS),x86),)
CROSS_DEV_PREFIX ?= /usr/local/genode-gcc/bin/genode-x86-
endif
ifeq ($(filter-out $(SPECS),arm),)
CROSS_DEV_PREFIX ?= /usr/local/genode-gcc/bin/genode-arm-
endif

#
# We use libsupc++ from g++ version 3 because
# this version does not use thread-local storage
# via the gs register. This is an interim solution.
#
#CUSTOM_CXX_LIB = g++-3.4

#
# The default optimization level used for compiling is -O2.
# By defining the variable CC_OLEVEL, you can override this
# default value, for example to optimize your binaries for size.
#
#CC_OLEVEL = -Os

#
# If CC_OPT should be extended please use concatenation syntax like:
#
#CC_OPT += -ffunction-sections -fdata-sections

#
# If CXX_LINK_OPT (linker options given to CXX)  should be extended please use
# concatenation syntax like:
#
#CXX_LINK_OPT += -Wl,-gc-sections

#
# On non-GNU systems, you may direct the build system to use GNU-
# specific tools.
