#################### COMPILE OPTIONS #######################

# Uncomment this for fixed-point build
#FIXED_POINT=1

# It is strongly recommended to uncomment one of these
# VAR_ARRAYS: Use C99 variable-length arrays for stack allocation
# USE_ALLOCA: Use alloca() for stack allocation
# If none is defined, then the fallback is a non-threadsafe global array
CFLAGS := -DUSE_ALLOCA $(CFLAGS)
#CFLAGS := -DVAR_ARRAYS $(CFLAGS)

# These options affect performance
# HAVE_LRINTF: Use C99 intrinsics to speed up float-to-int conversion
#      inline: Don't use the 'inline' keyword (for ANSI C compilers)
#    restrict: Don't use the 'restrict' keyword (for pre-C99 compilers)
#CFLAGS := -DHAVE_LRINTF $(CFLAGS)
#CFLAGS := -Dinline= $(CFLAGS)
CFLAGS := -Drestrict= $(CFLAGS)
