# Parameters:
|

|
|
# The first parameter is a space-separated list of the architectures the
|
|
# compilers will run on. For instance, "ppc i386". If the current machine
|
|
# isn't in the list, it will (effectively) be added.
|
|
# FIXME: HOSTS is not used in this script. Use it or Remove it.
|

# The second parameter is a space-separated list of the architectures the

# compilers will generate code for. If the current machine isn't in the list, a
|
|
# compiler for it will get built anyway, but won't be installed.
|
|
TARGETS="$2"
|

|
# The third parameter is the path to the compiler sources. There should be a
|
|
# shell script named 'configure' in this directory. This script makes a copy...
|
|
ORIG_SRC_DIR="$3"
|
|

|
|
# move it once it's built, so this mostly controls the layout of $DEST_DIR.
|

# The fifth parameter is the place where the compiler will be copied once it's
|
|
# built.
|
|

|
|
|
|
# The sixth parameter is a directory in which to place information (like
|
|
# unstripped executables and generated source files) helpful in debugging the
|
|
# resulting compiler.
|
|
SYM_DIR="$6"
|
|
|
|
# The seventh parameter is the version number of the submission, e.g. 1007.

# The eighth parameter is the subversion number of the submission, e.g. 03.

|
|
# enabled in the LLVM libs/tools.

# The current working directory is where the build will happen. It may already
