					  # default include path to the preprocessor.
#CFLAGS += --nostdlib # This will prevent the compiler from passing on the
 					  # default library path to the linker.

#CFLAGS += --less-pedantic # Disable some of the more pedantic warnings.

CFLAGS += --float-reent # Floating point library is compiled as reentrant.

#CFLAGS += --no-peep
#CFLAGS += --funsigned-char # The default signedness for every type will be unsigned.
#CFLAGS += --cyclomatic # This option will cause the compiler to generate an information
 						# message for each function in the source file. The message contains
 						# the number of edges and nodes the compiler detected in the
 						# control flow graph of the function, and most importantly
						# the cyclomatic complexity.

# ----- optimization options -----
#CFLAGS += --nogcse # Will not do global subexpression elimination, this option may be used
 					# when the compiler creates undesirably large stack/data spaces to store
 					# compiler temporaries.
#CFLAGS += --noinvariant # Will not do loop invariant optimizations.
#CFLAGS += --noinduction # Will not do loop induction optimizations.
#CFLAGS += --nojtbound # Will not generate boundary condition check when switch statements
 						# are implemented using jumptables.
#CFLAGS += --noloopreverse # Will not do loop reversal optimization.
#CFLAGS += --nolabelopt # Will not optimize labels (makes the dumpfiles more readable).
 CFLAGS += --nooverlay # The compiler will not overlay parameters and local variables of any function.

 #CFLAGS += --opt-code-speed # Optimize for code speed rather than size

# ----- special options for pic16 port of SDCC -----

# don't use extended instruction set - SDCCman, $4.6.20.1 Known Bugs
