# Improved optimisation options from qmake defaults.
# The README contains some timings showing the (fairly small) effect of changing these.

# Use the next two lines for slight improvement
# Now leaving these ON for general distribution as they DO have SOME effect and should be portable.

# The following architecture options make the compiled executables less portable.
# (On a different setup you may need to change what's subtracted out of the flags.)
# NB -march=X implies -mcpu=X... no need to specify both the same
#
# Use the next two lines ONLY IF you have the right processor (P4)
#MAKE_CXXFLAGS_RELEASE -= -march=i386 -mcpu=i686
#MAKE_CXXFLAGS_RELEASE += -march=pentium4 -mfpmath=sse -msse2
#
# Here's the same thing for P3 
#QMAKE_CXXFLAGS_RELEASE -= -march=i386 -mcpu=i686
#QMAKE_CXXFLAGS_RELEASE += -march=pentium3 -mfpmath=sse -msse

# Here's the same thing (UNTESTED) for Athalon-XP
#QMAKE_CXXFLAGS_RELEASE -= -march=i386 -mcpu=i686
#QMAKE_CXXFLAGS_RELEASE += -march=athalon-xp -mfpmath=sse -msse
#
# The next line seems to generate nicer assembler (with better SSE register usage) from some templated code.
# WARNING: gcc grows HUGE (>500MB!!!) and it takes AGES (30mins!!!) with this option.
# Of curiosity value for the hardcore only.

# Other stuff:
# Disable implicit cast from QString to/from char* - we should be using .local8Bit and ::fromLocal8Bit
# NB We don't use the corresponding -DQT_NO_CAST_ASCII because it breaks QString("...") which is used all over the place
# This probably wouldn't be usable until all the strings were moved out of the app - see Qt I18N docs.
# Also add gcc threading option (not entirely clear whether this is needed but it doesn't seem to hurt)

# OPTION: Use this to link vs ccmalloc library
# (This hasn't been particularly useful though;
# the only memory leaks so far have been related
# to inter-thread comms and timing dependent.
# Linking vs ccmalloc (or using vgrind) changed timings
# and caused the leak to disappear.)
