# configure.host
2
 
3
# This shell script handles all host based configuration for newlib.
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
# FIXME: This script is too complicated.  It does things in too many
13
# different ways.  This was taken from the old Cygnus configure script
14
# with only minor changes.  It should be cleaned up.
15
 
16
# FIXME: The general approach of picking and choosing which
17
# directories to configure, other than machine_dir and sys_dir, is
18
# potentially confusing.
19
 
20
# It uses the following shell variables:
21
#   host                The configuration host
22
#   host_cpu            The configuration host CPU
23
#   newlib_mb           --enable-newlib-mb ("yes", "no")
24
#   target_optspace     --enable-target-optspace ("yes", "no", "")
25
#   newlib_multithread  --enable-newlib-multithread ("yes", "no", "yes")
26
#   newlib_elix_level   --enable-newlib-elix-level ("1","2","3","4") ("4")
27
#   newlib_io_c99_formats --enable-newlib-io-c99-formats ("yes", "no", "")
28
#   newlib_io_long_long --enable-newlib-io-long-long ("yes", "no", "")
29
#   newlib_io_long_double --enable-newlib-io-long-double ("yes", "no", "")
30
 
31
# It sets the following shell variables:
32
#   newlib_cflags       Special CFLAGS to use when building
33
#   machine_dir         Subdirectory of libc/machine to configure
34
#   sys_dir             Subdirectory of libc/sys to configure
35
#   have_sys_mach_dir   Is there a machine subdirectory in sys subdirectory
36
#   posix_dir           "posix" to build libc/posix, "" otherwise
37
#   signal_dir          "signal" to build libc/signal, "" otherwise
38
#   stdio64_dir         "stdio64" to build libc/stdio64, "" otherwise
39
#   syscall_dir         "syscalls" to build libc/syscalls, "" otherwise
40
#   unix_dir            "unix" to build libc/unix, "" otherwise
41
#   use_libtool         flag: use libtool to build newlib?
42
#   aext                library extension - needed for libtool support
43
#   oext                object file extension - needed for libtool support
44
#   lpfx                library object prefix - generated when no libtool
45
#   crt1                name of crt1 object if one is provided
46
#   crt1_dir            directory where crt1 object is found
47
#   have_crt0           "yes"/"no" if crt0 is/isn't provided.
48
#                       "" if crt0 is provided when sys_dir is set
