# configure.host

|
|
# This shell script handles all host based configuration for the garbage
|
|
# collector.
|
|
# It sets various shell variables based on the the host and the
|
|
# configuration options. You can modify this shell script without
|
|
# needing to rerun autoconf.
|
|
|
|
# This shell script should be invoked as
|
|
# . configure.host
|
|
# If it encounters an error, it will exit with a message.
|
|
|
|
# It uses the following shell variables:
|
|
# host The configuration host
|
|
# host_cpu The configuration host CPU
|
|
# target_optspace --enable-target-optspace ("yes", "no", "")
|
|
# GCC should be "yes" if using gcc
|
|
|
|
# It sets the following shell variables:
|
|
# gc_cflags Special CFLAGS to use when building
|
|
# gc_use_mmap Set to "yes" on platforms where mmap should be used instead
|
|
# of sbrk. This will define USE_MMAP.
