of the lzf_compress API by default. This is because there is evidently
code floating around out there in the world with broken autoconf scripts that
don't check for LZF_STATE_ARG in the lzf header files and just assume the
dumb version of the API.
We rename the sane API to lzf_compress_r and implement the dumb API in
terms of it. Consequently, bump liblzf major version number. This is
fine because nothing used our liblzf with the old API.
Add lzf(1) utility from LZF distribution. Add manual page for lzf(1).
dynamically loaded module (.so) supplementing npfctl(8) and a kernel
module. Move normalisation and logging functionality into their own
extensions. More improvements to come.
the TLS pointer, therefore wrecking the pthread environement.
Some ports had _UC_TLSBASE flag or equivalent (_UC_UNIQUE on alpha)
that controlled whether setcontext() would change the TLS pointer.
This change let libpthread override setcontext() with its own version
that unsets _UC_TLSBASE, enabling safe usage of setcontext() with
-lpthread.
We also have the following required changes here:
- rename alpha's _UC_UNIQUE into _UC_TLSBASE
- add _UC_TLSBASE definition in header file for all ports
(powerpc, sh3, sparc and sparc64 lack the implementation for now)
- introduce a libc stub that can be overriden for setcontext()
- modify MD libcs swapcontext() implementations so that they use the
setcontext() libc stub instead of doing a plain system call.
While we are there:
- document various MD _UC_* flags in header file
- add libc and libpthread tests for swapcontext() behavior
(hopefully helpful to spot MD problems introduced with this change)
Future work:
- Deciding whether kernel support or _UC_TLSBASE should be added for
powerpc, sh3, sparc and sparc64 is left to portmasters

Contrary to the AMD implementation, it doesn't use xcalls to distribute
the update to all CPUs but relies on cpuctl(8) to bind itself to the
right CPU -- to keep it simple and avoid possible problems with
hyperthreading.
Also, it doesn't parse the vendor supplied file to pick the right
part for the present CPU model but relies on userland to prepare
files with specific filenames. I'll commit a pkg for this in a minute
(pkgsrc/sysutils/intel-microcode).
The ioctl interface changed; compatibility is provided (should be
limited to COMPAT_NETBSD6 as soon as this is available).
The main goal of this change is to simplify the further addition of test
cases for the share/mk infrastructure by adding a few placeholder test
programs to the tests tree.
To not leave these test programs empty, I have added a bunch of extremely
simple test cases to them.
- Merge h_regex_att (att.c) and t_regex_att.sh into a single C test program.
The former was really a test program, and the latter just a very strange
driver for it.
- Stop using awk to generate the shell test programs. This is unnecessary
and confusing. Instead, change t_regex.sh to generate the test case
functions on the fly with eval (as done in many other places).
