# $FreeBSD$
#
# All library objects contain FreeBSD revision strings by default; they may be
# excluded as a space-saving measure. To produce a library that does
# not contain these strings, add -DSTRIP_FBSDID (see <sys/cdefs.h>) to CFLAGS
# below. Note, there are no IDs for syscall stubs whose sources are generated.
# To included legacy CSRG sccsid strings, add -DLIBC_SCCS and -DSYSLIBC_SCCS
# (for system call stubs) to CFLAGS below. -DSYSLIBC_SCCS affects just the
# system call stubs.
Convert NO_PROFILE and NO_LIB32 to new style.

Remove libc, librtld_db, libthr packages, and further increase the constraints on what needs to be installed in a specific to maintain consistency during upgrades. Create a new clibs package containing libraries that are needed as a bare minimum for consistency. With much help and input from: kib Sponsored by: The FreeBSD Foundation

Enable symbol versioning by default. Use WITHOUT_SYMVER to disable it. Warning, after symbol versioning is enabled, going back is not easy (use WITHOUT_SYMVER at your own risk). Change the default thread library to libthr. There most likely still needs to be a version bump for at least the thread libraries. If necessary, this will happen later.

libthr: Use CLI flags instead of pragmas to disable warnings People tweaking the build system or compilers tend to look into the Makefile and not into the source. Having some warning controls in the Makefile and some in the source code is surprising. Pragmas have the advantage that they leave the warnings enabled for more code, but that advantage isn't very relevant in these cases.

To support stack unwinding for cancellation points, add -fexceptions flag for them, two functions _pthread_cancel_enter and _pthread_cancel_leave are added to let thread enter and leave a cancellation point, it also makes it possible that other functions can be cancellation points in libraries without having to be rewritten in libthr.

Merge from tbemd, with a small amount of rework: For all libthr contexts, use ${MACHINE_CPUARCH} for all libc contexts, use ${MACHINE_ARCH} if it exists, otherwise use ${MACHINE_CPUARCH} Move some common code up a layer (the .PATH statement was the same in all the arch submakefiles). # Hope she hasn't busted powerpc64 with this...

Merge all the copies of _tcb_ctor and _tcb_dtor. The amd64, i386, and sparc64 versions were identical, with the one difference where the former two used inline asm instead of _tcb_get. I have compared the function before and after replacing the asm with _tcb_get and found the object files to be identical. The arm, mips, and powerpc versions were almost identical. The only difference was the powerpc version used an alignment of 1 where arm and mips used 16. As this is an increase in alignment is will be safe. Along with this arm, mips, and powerpc all passed, when initial was true, the value returned from _tcb_get as the first argument to _rtld_allocate_tls. This would then return this pointer back to the caller. We can remove these extra calls by checking if initial is set and setting the thread control block directly. As this is what the sparc64 code does we can use it directly. As after these observations all the architectures can now have identical code we can merge them into a common file.
