# 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.

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. 2007-05-13 14:12:40 +00:00

Add a commented out CFLAGS entry that can be uncommented to compile thread lock debug into libc_r. I don't know if this is the best place to document this, but at least it is recorded somewhere. 8-) 1998-06-09 23:25:13 +00:00

Use growable stacks for thread stacks that are the default stack size. Cache discarded default thread stacks for use in subsequent thread creations. Create a red zone at the end of each stack (including the initial thread stack), with the hope of causing a segfault if a stack overflows. To activate these modifications, add -D_PTHREAD_GSTACK to CFLAGS in src/lib/libc_r/Makefile. Since the modifications depend on the VM_STACK kernel option, I'm not sure how to safely use growable stacks by default. Testing, as well as algorithmic and stylistic comments are welcome. 1999-07-05 00:35:19 +00:00			`CFLAGS+=-D_LOCK_DEBUG`

Change libkse back to libpthread and make it the default thread library for i386, amd64, and ia64. For alpha and sparc64 the library is not changed and remains libkse, and links are installed so that libpthread -> libc_r. The gcc -pthread option will be changed in a separate commit so that it links to -lpthread instead of -lc_r.
