# SRC_HC_OPTS += -O
# SRC_HC_OPTS includes flags to be added to *every* Haskell
# compilation. Setting SRC_HC_OPTS is a good way to set the default
# optimisation level (-O) and heap size (-H<size>).
#
# SRC_HC_OPTS is *not* for adding flags that are required to make your
# build work. Examples:
#
# - instead of using -pgmc/-pgma-/-pgml, use the --with-gcc option to configure
#
# - if you need -optc, -opta, or -optl flags, the CONF_CC_* and CONF_LD_*
# variables are more appropriate (set via configure)
#
# Note that SRC_HC_OPTS are added to every Haskell compilation,
# including when using the bootstrapping compiler (stage 0), So don't
# put options here that are only supported by very recent GHCs.
#
SRC_HC_OPTS += -H32m -O
# These flags make flex 8-bit
