ONLY_FOR_PLATFORM because lwp uses ucontext in preference to the old
process.s asm code.
New in 2.3:
* LWP builds and passes simple tests on amd64/em64t.
* Avoid crash when running lwp_basher.
* Work around broken makecontext on amd64
* Fix warning in rw.c
* Fix some autoconf/automake warnings during bootstrap.
* On bootstrap, get rid of the autom4te.cache. (Phil Nelson)
* struct ucontext changed to struct lwp_ucontext. (Phil Nelson)
New in 2.2:
* Removed cross-compilation spec files.
* Avoid stack overflow in the tdb test program on sparc64.
* FC5 build fixes.
* Don't package the link created by ldconfig.
New in 2.1:
* Sometimes we can only switch to a context created by makecontext once.
Refreshing the context information with getcontext to make the jump into the
thread reaper repeatable.
* Move declarations before code, gcc-2.95 likes that better. (Greg Troxel)
* The uc_stack in a ucontext may be clobbered by the context switching
functions. Use a separate copy in the lwp process info for stack overflow
checks and deallocation purposes.
* Use setjmp/longjmp to jump out of the signal context when using sigaltstack
to spawn a new thread instead of simply returning. This avoids corruption of
the newly created context. (Phil Nelson)
New in 2.0:
* Use ucontext.h provided functions for thread creation and switching.
In case those are not available use sigaltstack for thread creation
and sigsetjmp/siglongjump for thread switching, and if sigaltstack
doesn't exist fall back on the old process.S assembly code.
* Simplified pthread support a bit, now it builds and runs on cygwin.
* RPM .spec file fix to allow non-root users to build (Matthew Rich).
* Included AIX process.S assembly, since I don't know the right ifdefs,
it isn't actually part of process.S yet.
* This library is binary compatible with previous releases. But some of
the prototypes of callback functions got cleaned up a bit so that
building against this version of LWP will give some trivially fixable
compile warnings or errors.
New in 1.13:
* Stack switching code for AMD64 processors (Brett Lymn).
buildlink2.mk files back into the main trunk. This provides sufficient
buildlink2 infrastructure to start merging other packages from the
buildlink2 branch that have already been converted to use the buildlink2
framework.
