# Machine- or installation dependent flags you should configure to port

SASR	= -DSASR
######### Define SASR if >> is a signed arithmetic shift (-1 >> 1 == -1)

#MULHACK = -DUSE_FLOAT_MUL
######### Define this if your host multiplies floats faster than integers,
######### e.g. on a SPARCstation.

#FAST	= -DFAST
######### Define together with USE_FLOAT_MUL to enable the GSM library's
######### approximation option for incorrect, but good-enough results.

# LTP_CUT	= -DLTP_CUT
LTP_CUT	=
######### Define to enable the GSM library's long-term correlation 
######### approximation option---faster, but worse; works for
######### both integer and floating point multiplications.
######### This flag is still in the experimental stage.

WAV49	= -DWAV49
#WAV49	=
######### Define to enable the GSM library's option to pack GSM frames 
######### in the style used by the WAV #49 format.  If you want to write
######### a tool that produces .WAV files which contain GSM-encoded data,
######### define this, and read about the GSM_OPT_WAV49 option in the
######### manual page on gsm_option(3).

#The problem with sparc is the best stuff is in newer versions of gcc (post 3.0) only.
#This works for even old (2.96) versions of gcc and provides a small boost either way.
#A ultrasparc cpu is really v9 but the stock debian stable 3.0 gcc doesn't support it.
#So we go lowest common available by gcc and go a step down, still a step up from
#the default as we now have a better instruction set to work with. - Belgarath
