Revision 1.330, Mon Aug 26 04:49:45 2019 UTC (4 years, 6 months ago) by kamil
Branch: MAIN
Changes since 1.329: +2 -2 lines

Correct the build rules of LLVM sanitizers

Fix generation of .a.syms files in LLVM sanitizers. The old rules weren't
functional and sometimes they were fatal in the build.

Add the .a.syms files to distribution sets.
These files are generated only in certain .a files in 64bit version of
sanitizers.

Correct the location of files with LLVM sanitizers. Move the LLVM sanitizer
entries from base to comp files.

#	$NetBSD: Makefile,v 1.330 2019/08/26 04:49:45 kamil Exp $

#
# This is the top-level makefile for building NetBSD. For an outline of
# how to build a snapshot or release, as well as other release engineering
# information, see http://www.NetBSD.org/developers/releng/index.html
#
# Not everything you can set or do is documented in this makefile. In
# particular, you should review the files in /usr/share/mk (especially
# bsd.README) for general information on building programs and writing
# Makefiles within this structure, and see the comments in src/etc/Makefile
# for further information on installation and release set options.
#
# Variables listed below can be set on the make command line (highest
# priority), in /etc/mk.conf (middle priority), or in the environment
# (lowest priority).
#
# Variables:
#   DESTDIR is the target directory for installation of the compiled
#	software. It defaults to /. Note that programs are built against
#	libraries installed in DESTDIR.
#   MKMAN, if `no', will prevent building of manual pages.
#   MKOBJDIRS, if not `no', will build object directories at
#	an appropriate point in a build.
#   MKSHARE, if `no', will prevent building and installing
#	anything in /usr/share.
#   MKUPDATE, if not `no', will avoid a `make cleandir' at the start of
#	`make build', as well as having the effects listed in
#	/usr/share/mk/bsd.README.
#   NOCLEANDIR, if defined, will avoid a `make cleandir' at the start
#	of the `make build'.
#   NOINCLUDES will avoid the `make includes' usually done by `make build'.
#   NOBINARIES will not build binaries, only includes and libraries
#
#   See mk.conf(5) for more details.
#
#
# Targets:
#   build:
#	Builds a full release of NetBSD in DESTDIR, except for the
#	/etc configuration files.
#	If BUILD_DONE is set, this is an empty target.
#   distribution:
#	Builds a full release of NetBSD in DESTDIR, including the /etc
#	configuration files.
#   buildworld:
#	As per `make distribution', except that it ensures that DESTDIR
#	is not the root directory.
#   installworld:
#	Install the distribution from DESTDIR to INSTALLWORLDDIR (which
#	defaults to the root directory).  Ensures that INSTALLWORLDDIR
#	is not the root directory if cross compiling.
#   release:
#	Does a `make distribution', and then tars up the DESTDIR files
#	into ${RELEASEDIR}/${RELEASEMACHINEDIR}, in release(7) format.
#	(See etc/Makefile for more information on this.)
#   regression-tests:
#	Runs the regression tests in "regress" on this host.
#   sets:
#	Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/sets
#	from ${DESTDIR}
#   sourcesets:
#	Populate ${RELEASEDIR}/source/sets from ${NETBSDSRCDIR}
#   syspkgs:
#	Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/syspkgs
#	from ${DESTDIR}
#   iso-image:
#	Create CD-ROM image in RELEASEDIR/images.
#	RELEASEDIR must already have been populated by `make release'
#	or equivalent.
#   iso-image-source:
#	Create CD-ROM image with source in RELEASEDIR/images.
#	RELEASEDIR must already have been populated by
#	`make release sourcesets' or equivalent.
#   live-image:
#	Create bootable live image for emulators or USB stick etc.
#	in RELEASEDIR/liveimage.
#	RELEASEDIR must already have been populated by `make release'
#	or equivalent.
#   install-image:
#	Create bootable installation image for USB stick etc.
#	in RELEASEDIR/installimage.
#	RELEASEDIR must already have been populated by `make release'
#	or equivalent.
#
# Targets invoked by `make build,' in order:
#   cleandir:        cleans the tree.
#   do-top-obj:      creates the top level object directory.
#   do-tools-obj:    creates object directories for the host toolchain.
#   do-tools:        builds host toolchain.
#   params:          record the values of variables that might affect the
#                    build.
#   obj:             creates object directories.
#   do-distrib-dirs: creates the distribution directories.
#   includes:        installs include files.
#   do-lib:          builds and installs prerequisites from lib.
#   do-compat-lib:   builds and installs prerequisites from compat/lib
#                    if ${MKCOMPAT} != "no".
#   do-x11:          builds and installs X11 tools and libraries
#                    from src/external/mit/xorg if ${MKX11} != "no".
#   do-build:        builds and installs the entire system.
#   do-extsrc:       builds and installs extsrc if ${MKEXTSRC} != "no".
#   do-obsolete:     installs the obsolete sets (for the postinstall-* targets).
