### Compiler and linker switches

# Enable/disable debugging:

CXXFLAGS += -DNDEBUG


# Compile with full warnings, and symbol names

CXXFLAGS += -Wall -g


# General optimization flags.  Note that -O2 might be faster than -O3 on some
# systems; this requires testing.

CXXFLAGS += -O3 -fno-exceptions -fomit-frame-pointer -fno-rtti -fno-strict-aliasing

# Disable most annoying warnings for the Intel C++ compiler

CXXFLAGS += -wd383,869,981


# Compiler optimization flags for the Intel C++ compiler in Mac OS X:

# CXXFLAGS += -mdynamic-no-pic -no-prec-div -ipo -static -xP


# Profiler guided optimization with the Intel C++ compiler.  To use it, first
# create the directory ./profdata if it does not already exist, and delete its
# contents if it does exist.  Then compile with -prof_gen, and run the
# resulting binary for a while (for instance, do ./glaurung bench 128 1, and
# wait 15 minutes for the benchmark to complete).  Then do a 'make clean', and
# recompile with -prof_use.

# CXXFLAGS += -prof_gen -prof_dir profdata
# CXXFLAGS += -prof_use -prof_dir ./profdata


# Profiler guided optimization with GCC.  I've never been able to make this
# work.

# CXXFLAGS += -fprofile-generate
# LDFLAGS += -fprofile-generate
# CXXFLAGS += -fprofile-use
# CXXFLAGS += -fprofile-use


# General linker flags

LDFLAGS += -lm -lpthread


# Compiler switches for generating binaries for various CPUs in Mac OS X.
# Note that 'arch ppc' and 'arch ppc64' only works with g++, and not with
# the intel compiler.

# CXXFLAGS += -arch ppc
# CXXFLAGS += -arch ppc64
