1# configure.host
2
3# This shell script handles all host based configuration for libgcj.
4# It sets various shell variables based on the the host and the
5# configuration options. You can modify this shell script without
6# needing to rerun autoconf.
7
8# This shell script should be invoked as
9# . configure.host
10# If it encounters an error, it will exit with a message.
11
12# It uses the following shell variables:
13# host The configuration host
14# host_cpu The configuration host CPU
15# target_optspace --enable-target-optspace ("yes", "no", "")
16
17# It sets the following shell variables:
18# libgcj_cflags Special CFLAGS to use when building
19# libgcj_cxxflags Special CXXFLAGS to use when building
20# libgcj_javaflags Special JAVAFLAGS to use when building
21# libgcj_interpreter If the bytecode interpreter supports this platform.
22# enable_java_net_default If java.net native code should be enabled by
23# default.
24# enable_hash_synchronization_default If hash synchronization should be
25# enabled by default.
26# sysdeps_dir Directory containing system-dependent headers
27# slow_pthread_self The synchronization code should try to avoid
28# pthread_self calls by caching thread IDs in a hashtable
29# can_unwind_signal Set to "yes" if the EH unwinder supports throwing
30# from a signal handler.
