The magic runtime library is now built as part of the regular build, if the MKMAGIC=yes flag is passed to the build system. The library has been renamed from "magic" to "magicrt" to resolve a name clash with BSD file(1)'s libmagic. All its level-5 LLVM warnings have been resolved. The final library, "libmagicrt.bcc", is now stored in the destination library directory rather than in the source tree. Change-Id: Iebd4b93a2cafbb59f95d938ad1edb8b4f6e729f6

|
# The magic runtime library is the runtime state transfer component for live
|
|
# update. It is not a regular library. First of all, it is only built when
|
|
# MKMAGIC is enabled, which also implies that we are building bitcode.
|
|
# Second, the produced file is a single bitcode object containing basically the
|
|
# concatenation of the individual bitcode objects produced from the source
|
|
# files. The final bitcode object is used to link against system services
|
|
# during the rest of the compilation process. It is installed only because
|
|
# this makes it easier to refer to it during the rest of the compilation
|
|
# process. However, both the library's generation and its installation cannot
|
|
# be done with regular bsd.lib.mk rules, which is why this Makefile is rather
|
|
# nonstandard.
