6# Build LLVM the "Apple way".
7# Parameters:
8
9# The first parameter is a space-separated list of the architectures the
10# compilers will run on. For instance, "ppc i386". If the current machine
11# isn't in the list, it will (effectively) be added.
12# FIXME: HOSTS is not used in this script. Use it or Remove it.
13HOSTS="$1"
14
15# The second parameter is a space-separated list of the architectures the
16# compilers will generate code for. If the current machine isn't in the list, a
17# compiler for it will get built anyway, but won't be installed.
18TARGETS="$2"
19
20# The third parameter is the path to the compiler sources. There should be a
21# shell script named 'configure' in this directory. This script makes a copy...
22ORIG_SRC_DIR="$3"
23
24# The fourth parameter is the location where the LLVM will be installed. You can
25# move it once it's built, so this mostly controls the layout of $DEST_DIR.
26DEST_ROOT="$4"
27
28# The fifth parameter is the place where the compiler will be copied once it's
29# built.
30DEST_DIR="$5"
31
32# The sixth parameter is a directory in which to place information (like
33# unstripped executables and generated source files) helpful in debugging the
34# resulting compiler.
35SYM_DIR="$6"
36
37# The seventh parameter is a yes/no that indicates whether assertions should be
38# enabled in the LLVM libs/tools.
39LLVM_ASSERTIONS="$7"
40
41# The eighth parameter is a yes/no that indicates whether this is an optimized
42# build.
43LLVM_OPTIMIZED="$8"
44
45# The nineth parameter is the version number of the submission, e.g. 1007.
46LLVM_SUBMIT_VERSION="$9"
47
48# The tenth parameter is the subversion number of the submission, e.g. 03.
49LLVM_SUBMIT_SUBVERSION="${10}"

52# contain a partial result of an interrupted build, in which case this script
