-# Open Issues
-
-`threads = yes` is set in `debian/sysdeps/linux.mk` and
-`debian/sysdeps/kfreebsd.mk`, `debian/sysdeps/hurd.mk` set to `no`.  But this
-is only read in `debian/rules` for deciding some `nscd` package issue?
-
-`debian/sysdeps/hurd.mk`'s `libc_extra_install` for `ld.so`: check with GCC
-configuration.
-
-Could add a toggle to `$(stamp)build_%` in `debian/rules.d/build.mk` to skip
-locale stuff.
-
-`--disable-compatible-utmp`?
-
-
-# Building
-
-Run `debian/rules patch` to apply patches (instead of having it done during the
-build).  Then you can edit files manually.
-
-Several passes: `libc`, `i686`, `xen`; `EGLIBC_PASSES='libc i686'`, etc.
-
-If building with `EGLIBC_PASSES=libc` (more specifically, without `xen`), the
-`libc0.3-dev_extra_pkg_install` rule in `debian/sysdeps/hurd-i386.mk` will
-fail.  (Same for `libc6-dev_extra_pkg_install` in `debian/sysdeps/i386.mk`, for
-example.)  Why is this special handling only done for `xen`, but not for
-`i686`?
-
-> Samuel: Historically because it's done that way in linux-i386. I don't know
-> the real reason.
-
-Do `export LC_ALL=C` before building, otherwise the testsuite/make error
-messages will be different from those stored in the
-`debian/testsuite-checking/expected-results-*` files, resulting in a spurious
-build failure.
-
-Run `debian/rules build-arch DEB_BUILD_OPTIONS=parallel=2 [EGLIBC_PASSES=...]`
-to build (or `build` instead of `build-arch` to build the arch-independent
-stuff, too).  Can interrupt with `C-c` during locale stuff or testsuite if only
-interested in the build tree.
-
-Run `fakeroot debian/rules binary DEB_BUILD_OPTIONS=parallel=2
-[EGLIBC_PASSES=...]` to build Debian packages or `binary-arch` for just the
-architecture-dependent ones.
-
-The latter two steps can also be combined as `dpkg-buildpackage -R'debian/rules
-EGLIBC_PASSES=libc' -nc -b -uc`.  `-nc` will prevent the *clean step* which
-would first try to un-patch, which may conflict if you have done any edits
-apter applying patches.
-
-If the Debian symbol versioning file is not up to date and the build of Debian
-packages fails due to this, putting `DPKG_GENSYMBOLS_CHECK_LEVEL=0` in the
-environment \`\`helps''; see `man dpkg-gensymbols`.

-
-This basically means to get rid of `sysdeps/mach/hurd/bits/libc-tsd.h` (and
-thus the `_HURD_THREADVAR_*`/`_hurd_threadvar_location` interface), and
-directly use `__thread` instead.
-
-IRC, freenode, #hurd, 2011-10-23:
-
-    <tschwinge> youpi: If we want to replace threadvars with TLS, there is one
-      problem: the threadvars interface is publically exported:
-      /usr/include/hurd/threadvar.h.
-    <tschwinge> youpi: But I am somewhat inclined to say that the only user of
-      this is libthreads/libpthread.  Do you think differently?
-    <youpi> tschwinge: that's very probable
-    <youpi> so I think we can just drop it
-    <youpi> (people should use TLS anyway)
-
-[[libpthread_set_stack_size]].
-
-After this has been done, probably the whole `__libc_tsd_*` stuff can be
-dropped altogether, and `__thread` directly be used in glibc.

-# To Do
-
-  * Discuss d2431f633e6139a62e1575ec18830f7e81160cf0 with Samuel.
-
-  * `TLS_INIT_TP_EXPENSIVE` is unused; Hurd def. can be removed.

-  * IRC, freenode, #hurd, 2011-11-26
-
-        <tschwinge> In glibc multiarch support (strcasecmp for i686 SSE3, etc.)
-          there is access to memory via gs: -- this will need to be changed for
-          us, right?
-        <youpi> depends on the access
-        <tschwinge>       * `optimized strcasecmp and strncasecmp for x86-32`
-          (multiarch),
-        <tschwinge>         76e3966e9efc3808a9e7ad09121c5dfc1211c20b +

-        <tschwinge>         5583a0862cf94f71cbcde91c4043a20af65facca.  `gs`
-          access.
-        <youpi> +       movl    __libc_tsd_LOCALE@GOTNTPOFF(%ebx), %eax
-        <youpi> that's handled by the linker fine
-        <youpi> it's only the things held in the tcb_t structure which can pose
-          problem
-        <tschwinge> tcbhead_t?
-        <tschwinge> I'm looking at this.
-        <tschwinge> So, at gs:0, there is the TCB.
-        <tschwinge> And we have the same layout as NPTL/Linux, just that we
-          don't have as much data there as they have.
-        <tschwinge> We're missing multiple_threads, sysinfo, sttack_guard,
-          pointer_guard, gscope_flag, private_futex, __private_tm[5].
-        <tschwinge> So, if one of these is referenced (be it my name or by
-          numeric offset), this is invalid for us.
-        <tschwinge> Anything else should work equivalently.
-        <youpi> yes
-        <youpi> usually the only numeric offset being used is 0
-        <youpi> so it would simply not build
-        <tschwinge> And the other offsers are generated via tcb-offsets.sym.
-        <tschwinge> glibc's elf/stackguard-macros.h is wrong for us (but not
-          used anywhere apart from elf/tst-stackguard1.c, I think).
-        <tschwinge> __thread __locale_t __libc_tsd_LOCALE = &_nl_global_locale;
-          -- this means that a __libc_tsd_LOCALE values will be in the TLS
-          segment, and this is what is being accessed from the assembler code
-          with %gs:__libc_tsd_LOCALE@NTPOFF, and the linker will resolve this.
-        <youpi> yes
-        <youpi> see in the nm output, the libc_tsd symbols
-        <youpi> these provide the offsets
-        <tschwinge> youpi: Thank you, I'm now understanding this part of TLS
-          much better.
-        <youpi> have you had a look at the tls.pdf from Uli ?
-        <youpi> all the gory details are there :)
