# Please review compilation options

# 1. Change this to your compiler (g++ 4.1 is recommended). If you're not using g++, check for equivalent options below.
# Set through Spring SConstruct
#CXX=g++

# 2. Set the correct type for your architecture
# Set through Spring SConstruct too
# 2a: One of:
#STREFLOP_SSE = 1
#STREFLOP_X87 = 1
#STREFLOP_SOFT = 1
# 2b. And optionally:
#STREFLOP_NO_DENORMALS = 1

# 3. Set optimization options. You may add -march=you_cpu here for example
CXXFLAGS = -O3 -pipe -g
#CXXFLAGS = -O0 -pipe -g


############################################################
# Options you may review if using another compiler than g++
############################################################

# 4. Optional, removes false dependency on libm
LDFLAGS=-Wl,--as-needed

# Options for correctness of code.
# -ffloat-store is not needed since the FPU flags are set by the streflop_init functions
CXXFLAGS += -frounding-math -fsignaling-nans -fno-strict-aliasing -mieee-fp -Wall

# The next options should match/select the FPU
ifdef STREFLOP_X87
CXXFLAGS += -mfpmath=387
endif
ifdef STREFLOP_SSE
CXXFLAGS += -mfpmath=sse -msse -msse2
