We've switched to a 3-component version numbering scheme for Apple releases, and with this scheme, the final number is the one most relevant for setting LLVM_MINOR_VERSION. <rdar://problem/12071459> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161645 91177308-0d34-0410-b5e6-96231b3b80d8

# Build LLVM the "Apple way".

# 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.
|
|
HOSTS="$1"
|
|
|
|
# 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.
|
|
# FIXME: The list of targets is currently hard-coded and TARGETS is not used.
|
|
TARGETS="$2"
|

|
|
# shell script named 'configure' in this directory. This script makes a copy...
|
|
ORIG_SRC_DIR="$3"
|

# The fourth parameter is the location where the LLVM will be installed. You can
|
|
# 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 a yes/no that indicates whether assertions should be
|
|
# enabled in the LLVM libs/tools.
|
|
LLVM_ASSERTIONS="$7"
|
|
|
|
# The eighth parameter is a yes/no that indicates whether this is an optimized
|
|
# build.
|
|

|
|
|
|
# A yes/no parameter that controls whether to cross-build for an ARM host.
