commit 2574ef747f50a3d33090749675c25d123b46b64d
Author: Zack Weinberg <zackw@panix.com>
Date: Wed Mar 22 10:55:38 2017 -0400
Remove __need_IOV_MAX and __need_FOPEN_MAX.
__need_FOPEN_MAX wasn't being used anywhere. __need_IOV_MAX was more
complicated; the basic deal is that sys/uio.h wants to define a
constant named UIO_MAXIOV and bits/xopen_lim.h wants to define a
constant named IOV_MAX, with the same meaning. For no apparent reason
this was being handled via bits/stdio_lim.h -- stdio.h is NOT supposed
to define IOV_MAX -- and some mess in Makerules. Also, bits/uio.h on
Linux was being used as a dumping ground for extension functions, and
there's no longer any good reason for the definition of struct iovec
itself to be system-dependent.
So now we have bits/uio_lim.h, which defines __IOV_MAX.
bits/xopen_lim.h and sys/uio.h use that to define their respective
constants. We also now have bits/types/struct_iovec.h, which is the
one true definition of struct iovec, used by sys/uio.h and
bits/fcntl-linux.h (another dumping ground for extension functions
which I am not tackling in this patch series), and sys/uio_ext.h,
which is the official Proper Home for extensions to sys/uio.h. And
stdio_lim.h doesn't define IOV_MAX at all.
* bits/uio_lim.h, sysdeps/unix/sysv/linux/bits/uio_lim.h
* misc/bits/types/struct_iovec.h, include/bits/types/struct_iovec.h
* sysdeps/generic/sys/uio_ext.h, sysdeps/unix/sysv/linux/sys/uio_ext.h:
New file.
* bits/uio.h, sysdeps/unix/sysv/linux/bits/uio.h: Delete file.
* include/bits/xopen_lim.h: Use bits/uio_lim.h to get the value
for IOV_MAX.
* misc/Makefile: Install sys/uio_ext.h, bits/uio_lim.h, and
bits/types/struct_iovec.h. Don't install bits/uio.h.
* misc/sys/uio.h: Use bits/types/struct_iovec.h to get the
definition of struct iovec, and bits/uio_lim.h to get the value
for UIO_MAXIOV. Under __USE_GNU, include sys/uio_ext.h.
* sysdeps/unix/sysv/linux/bits/fcntl-linux.h:
Use bits/types/struct_iovec.h to get the definition of struct
iovec. Use __ssize_t, not ssize_t, in function prototypes.
* stdio-common/stdio_lim.h.in: Remove logic for __need_FOPEN_MAX
and __need_IOV_MAX. Don't define IOV_MAX at all.
* Makerules (stdio_lim.h): Remove logic for setting IOV_MAX.

commit 2745df16e80c6dee73a025d9d48f8efcae636c34
Author: Zack Weinberg <zackw@panix.com>
Date: Wed Mar 22 09:55:25 2017 -0400
Remove __need_list_t and __need_res_state.
These __need macros are only used internally, by nptl/descr.h.
However, including all of resolv.h from descr.h causes build failures
due to resolv.h's dozens of pseudo-struct-field macros, some of which
collide with struct fields in NPTL internal data structures.
Similarly, including all of list.h from descr.h produces an include
cycle, atomic.h -> atomic-machine.h -> tls.h -> descr.h -> list.h ->
atomic.h, and then list.h tries to use atomic.h macros that haven't
been defined yet. So we do need mini-headers for these. In the
list.h case I called it include/list_t.h since it isn't going to be
installed.
* resolv/resolv.h: Remove __need_res_state logic.
Move definition of res_state and related constants to ...
* resolv/bits/types/res_state.h: ...this new file.
* resolv/Makefile: Install bits/types/res_state.h.
* include/bits/types/res_state.h: New wrapper.
* include/list.h: Remove __need_list_t logic.
Move definition of list_t to ...
* include/list_t.h: ...this new file.
* nptl/descr.h: Include list_t.h and bits/types/res_state.h
instead of list.h and resolv.h.

commit 68003c60786851009f42cda969d8b602c23b933f
Author: Zack Weinberg <zackw@panix.com>
Date: Tue Mar 21 16:30:53 2017 -0400
Remove __need macros from errno.h (__need_Emath, __need_error_t).
This is fairly complicated, not because the users of __need_Emath and
__need_error_t have complicated requirements, but because the core
changes had a lot of fallout.
__need_Emath is defined only by .S files; what they _really_ need is
for errno.h to avoid declaring anything other than the E-constants
(e.g. 'extern int __errno_location(void);' is a syntax error in
assembly language). This is replaced with a check for __ASSEMBLER__ in
errno.h, plus a carefully documented requirement for bits/errno.h not
to define anything other than macros. That in turn has the
consequence that bits/errno.h must not define errno - fortunately,
there were only two versions of the definition in a live port, so I
moved them to errno.h and added a new __GLIBC_USE macro to choose
between them. As a consequence of *that*, attribute_tls_model_ie
needed to move to sys/cdefs.h and be renamed __attribute_tls_model_ie__.
__need_error_t exists for gnulib compatibility in argz.h and argp.h.
error_t itself is a slightly-too-clever Hurdism, an enum containing
all the E-constants, so you can do 'p (error_t) errno' in gdb and get
a symbolic value. argz.h and argp.h want to fall back to 'int' when
that's not available. Also, to comply with the rule that bits/errno.h
may only define macros anymore, the definition of error_t had to be
removed from sysdeps/mach/hurd/bits/errno.h somehow. I have elected
to move error_t to a file generated at build time and make it
available for all supported hosts, not just Hurd. This allows
creation of a generic bits/types/error_t.h. However, the price is
that the new definition requires a GCC >=4.5 feature - otherwise it
falls back to 'int'. And you may regret reading the generated
bits/errno-enum.h.
* stdlib/errno.h: Remove __need_Emath and __need_error_t logic.
Include bits/types/error_t.h for error_t. Declare errno here,
using either __thread or __errno_location, as directed by
bits/errno.h. When __ASSEMBLER__ is defined, provide only the
E* constants, as macros. Reorganize file.
* stdlib/bits/types/error_t.h: New file.
* include/bits/types/error_t.h: New wrapper.
* scripts/make-errno-enum.sh: New file.
* Makeconfig: Add rules to generate bits/errno-enum.h.
(common-generated): Add bits/errno-enum.h and bits/errno-enum.h.stmp.
Also add dl-tunable-list.h and dl-tunable-list.stmp, missed in a
previous patch.
(dl-tunable-list.h): Generate using a stamp file.
* stdlib/Makefile: Install bits/types/error_t.h and bits/errno-enum.h.
* bits/errno.h: Remove logic for __need_Emath. Document
requirements for a port-specific bits/errno.h.
* include/errno.h: Change conditional for exposing internal
declarations to (not _ISOMAC and not __ASSEMBLER__).
* include/features.h (__GLIBC_USE_TLS_ERRNO): New feature
selection macro, defaults to 0.
* sysdeps/mach/hurd/errnos.awk
* sysdeps/nacl/errnos.awk
* sysdeps/unix/sysv/linux/bits/errno.h
* sysdeps/unix/sysv/linux/alpha/bits/errno.h
* sysdeps/unix/sysv/linux/hppa/bits/errno.h
* sysdeps/unix/sysv/linux/mips/bits/errno.h
* sysdeps/unix/sysv/linux/sparc/bits/errno.h:
Add multiple-include guard and check against improper inclusion.
Remove __need_Emath logic. Don't declare errno here. Ensure all
constants are defined as simple integer literals. Redefine
__GLIBC_USE_TLS_ERRNO to 1 if appropriate. Consistent formatting.
* sysdeps/mach/hurd/bits/errno.h: Regenerate.
* argp/argp.h, string/argz.h: Include bits/types/error_t.h for error_t.
* sysdeps/i386/i686/fpu/multiarch/s_cosf-sse2.S
* sysdeps/i386/i686/fpu/multiarch/s_sincosf-sse2.S
* sysdeps/i386/i686/fpu/multiarch/s_sinf-sse2.S

* sysdeps/x86_64/fpu/s_sincosf.S
* sysdeps/x86_64/fpu/s_sinf.S
Just include errno.h; don't define __need_Emath or include
bits/errno.h directly.
* include/libc-symbols.h (attribute_tls_model_ie): Remove.
* misc/sys/cdefs.h (__attribute_tls_model_ie__): New.
* elf/dl-error-skeleton.c, include/errno.h, include/netdb.h
* include/resolv.h, locale/localeinfo.h, malloc/arena.c
* sunrpc/rpc_thread.c, sysdeps/generic/libc-tsd.h

* sysdeps/ieee754/ldbl-opt/math_ldbl_opt.h
* sysdeps/powerpc/nofpu/soft-supp.h
* sysdeps/powerpc/soft-fp/sfp-machine.h
Use __attribute_tls_model_ie__ and/or __attribute_const__.

commit 1935f0763e10fe383e6c1b6d4514faafce0e01e2
Author: Zack Weinberg <zackw@panix.com>
Date: Thu Dec 1 19:24:13 2016 -0500
Convert signal.h from __need macros to bits/types/ headers.
This was considerably hairier than any of the preceding conversions,
because sigset_t is OS-dependent, and siginfo_t and sigevent_t are
both OS- and machine-dependent. And the bits headers that defined
them also defined a whole bunch of other stuff that was mostly _not_
OS- or machine-dependent. I have disentangled it as much as I think
is feasible short of going to generated headers.
Side effects include: There have been small changes to which non-signal
headers expose which subset of the signal-related types. A couple of
architectures' nested siginfo_t fields had to be renamed to prevent
undesired macro expansion (you know the thing where a perfectly
ordinary user-namespace identifier is defined as a macro expanding
to a chain of nested structure references? that thing is terrible).
Internal code that wants to manipulate signal masks must now include
<bits/sigsetops.h> (which is not installed) and should be aware that
__sigaddset, __sigandset, __sigdelset, __sigemptyset, and __sigorset no
longer return a value (unlike the public API, which returns 'int' solely
so that it can return -1 instead of crashing when given null pointers).
Relatedly, the public signal.h no longer declares any of those functions.
The obsolete sigmask() macro no longer has a system-specific definition --
in the cases where it matters, it didn't work anyway.
New Linux architectures should create bits/siginfo-arch.h and/or
bits/siginfo-consts-arch.h to customize their siginfo_t, rather than
duplicating everything in bits/siginfo.h (which no longer exists).
Add new __SI_* macros if necessary. Ports to other operating systems
are strongly encouraged to generalize this scheme further; I might do
a follow-on patch that unifies the Linux-generic bits headers with the
totally generic ones.
It might make sense to make bits/sigsetops.h into a new, public set of
inline functions (like the existing bits/string2.h) but it seems
unlikely that signal mask manipulation is performance-critical to
anyone, so I'm not inclined to bother.

commit 6358662fe70bfde2a1cccc4e887b33a7a27d078d
Author: Zack Weinberg <zackw@panix.com>
Date: Sun Nov 20 23:00:02 2016 -0500
The bits/types/*.h treatment for stdio and wchar.
wint_t is a little finicky because it might be defined by stddef.h, which
belongs to the compiler.
In addition to the _types_, a bunch of other declarations shared between
wctype.h and wchar.h are factored out to their own header.
* libio/bits/types/FILE.h, libio/bits/types/__FILE.h
* wcsmbs/bits/types/mbstate_t.h, wcsmbs/bits/types/__mbstate_t.h
* wcsmbs/bits/types/wint_t.h: New single-type definition files.
* wctype/bits/wctype-wchar.h: New file holding declarations shared
between wctype.h and wchar.h.
* libio/Makefile, wcsmbs/Makefile, wctype/Makefile:
Install them.
* include/bits/types/FILE.h, include/bits/types/__FILE.h
* include/bits/types/mbstate_t.h, include/bits/types/__mbstate_t.h
* include/bits/types/wint_t.h, include/bits/wcsmbs-wchar.h:
New wrappers.
* include/stdio.h, include/wchar.h, include/wctype.h:
No need to handle __need macros.
* grp/grp.h, gshadow/gshadow.h, hurd/hurd.h, iconv/gconv.h
* libio/stdio.h, mach/mach.h, misc/mntent.h, pwd/pwd.h
* shadow/shadow.h, stdio-common/printf.h, wcsmbs/uchar.h
* wcsmbs/wchar.h, wctype/wctype.h
* sysdeps/generic/_G_config.h, sysdeps/unix/sysv/linux/_G_config.h
Use the new files instead of __need macros.
