GNU C Library master sources branch zack/no-inline-string-opts created. glibc-2.25-299-g6e0c80e


This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "GNU C Library master sources".

The branch, zack/no-inline-string-opts has been created
        at  6e0c80ed95e5f0f8cd4262ceebb3e91dfe571790 (commit)

commit 6e0c80ed95e5f0f8cd4262ceebb3e91dfe571790
Author: Zack Weinberg <zackw@panix.com>
Date:   Thu Nov 17 09:26:27 2016 -0500

    For experimental purposes, remove bits/string.h.
    
    	* bits/string.h, string/bits/string.h
    	* sysdeps/aarch64/bits/string.h
    	* sysdeps/m68k/m680x0/m68020/bits/string.h
    	* sysdeps/s390/bits/string.h, sysdeps/sparc/bits/string.h
    	* sysdeps/x86/bits/string.h: Delete file.
    
    	* string/string.h: Don't include bits/string.h.
    	* string/bits/string3.h: Rename to bits/string_fortified.h.
    	No need to undef various symbols that the removed headers
    	might have defined as macros.
    	* string/Makefile (headers): Remove bits/string.h, change
            bits/string3.h to bits/string_fortified.h.
    	* string/string-inlines.c: Update commentary.  Remove definitions
    	of various macros that nothing looks at anymore.  Don't directly
    	include bits/string.h.  Set _STRING_INLINE_unaligned here, based on
    	compiler-predefined macros.
    	* string/strncat.c: If STRNCAT is not defined, or STRNCAT_PRIMARY
    	_is_ defined, provide internal hidden alias __strncat.
    	* include/string.h: Declare internal hidden alias __strncat.
    	Forward __bzero to __builtin_memset, __mempcpy to builtin_mempcpy,
    	and __stpcpy to __builtin_stpcpy here, if __NO_STRING_INLINES is
    	not defined.
    	* include/bits/string3.h: Rename to bits/string_fortified.h,
    	update to match above.
    
    	* sysdeps/i386/string-inlines.c: Define compat symbols for
    	everything formerly defined by sysdeps/x86/bits/string.h.
    	Make existing definitions into compat symbols as well.  Remove
    	some no-longer-necessary messing around with macros.
    
    	* sysdeps/powerpc/powerpc32/power4/multiarch/mempcpy.c
    	* sysdeps/powerpc/powerpc64/multiarch/mempcpy.c
    	* sysdeps/powerpc/powerpc64/multiarch/stpcpy.c
    	* sysdeps/s390/multiarch/mempcpy.c
    	No need to define _HAVE_STRING_ARCH_mempcpy.  Do define
    	__NO_STRING_INLINES and NO_MEMPCPY_STPCPY_REDIRECT.
    
    	* sysdeps/i386/i686/multiarch/strncat-c.c
    	* sysdeps/s390/multiarch/strncat-c.c
    	* sysdeps/x86_64/multiarch/strncat-c.c
    	Define STRNCAT_PRIMARY.  Don't change definition of libc_hidden_def.

commit bbb70ed62d4e207229f534b63f378d9d863283d9
Author: Zack Weinberg <zackw@panix.com>
Date:   Thu Apr 20 11:21:30 2017 -0400

    Don't install libio.h or _G_config.h.
    
    This is an experimental patch which removes libio.h (and _G_config.h)
    from the set of application-exposed headers.  After this change, the
    public stdio.h does not define any symbols whose names begin with _G_
    nor _IO_, except that when optimizing, the guts of struct _IO_FILE and
    three of the flag constants are visible (see bits/stdio.h and
    bits/types/FILE_internals.h).  There is a small amount of code
    duplication in bits/stdio.h, of macro bodies from libio.h that are no
    longer available.  A number of internal .c files that were manually
    doing PLT bypass for flockfile/funlockfile can now rely on
    include/stdio.h to do it for them.
    
    It passes the testsuite on x86_64-linux, but it needs a great deal of
    additional testing; in particular I'm almost certain I broke the
    support for old-format (GLIBC_2.0) struct _IO_FILE, which is
    configured out on this target.  Testing this properly would require
    someone to get their hands on _really_ old binaries, compiled against
    glibc 2.0, possibly statically-linked-but-using-NSS.  Unfortunately,
    libc.so cannot be expected to be binary identical.
    
    However, this should be ready to feed into archive rebuilds to find
    out what applications break.
    
    Substantial clean-ups to the libio implementation are possible if this
    sticks, but I haven't done 'em; this is intended to be minimal.
    
    	* libio/Makefile: Don't install libio.h or _G_config.h.  Do install
    	bits/types/FILE_internals.h, bits/types/cookie_io_functions_t.h,
    	and bits/types/__fpos_t.h.
    
    	* libio/stdio.h: Don't include libio.h.  Get __gnuc_va_list
    	directly from stdarg.h, __fpos_t and __fpos64_t from
    	bits/types/__fpos_t.h, and the cookie types from
    	bits/types/cookie_io_functions_t.h.  Change all uses of
    	_G_va_list, _G_fpos_t, _G_fpos64_t, _IO_FILE,
    	_IO_cookie_io_functions_t, and _IO_ssize_t to __gnuc_va_list,
    	__fpos_t, __fpos64_t, FILE, cookie_io_functions_t, and __ssize_t
    	respectively.
    	Do not define getc nor putc as macros.
    	Define BUFSIZ as literal 8192.
    
    	* libio/bits/types/FILE_internals.h: New header. Provide complete
    	definition of struct _IO_FILE (the complete version) here.
    	Duplicate definitions of _IO_EOF_SEEN, _IO_ERR_SEEN, and _IO_USER_LOCK
    	here, with value assertions if they are already defined.
    	* libio/bits/types/__fpos_t.h: New header. Define __fpos_t and
    	__fpos64_t here.
    	* libio/bits/types/cookie_io_functions_t.h: New header.  Define
    	cookie_read_function_t, cookie_write_function_t,
    	cookie_seek_function_t, cookie_close_function_t, and
    	cookie_io_functions_t here.
    
    	* libio/libio.h: Include features.h first thing, then error out if
    	either _LIBC or __USE_GNU is not defined, or if _ISOMAC is
    	defined.  Inline all of _G_config.h except _G_HAVE_MREMAP here.
    	Get definitions of __mbstate_t, __fpos_t, __fpos64_t, struct
    	_IO_FILE, and the cookie-related types from the relevant
    	bits/types headers.  Get definition of NULL from stddef.h.
    	Make all #ifdef _LIBC and #if __GNUC__ >= (2,3) blocks
    	unconditional.  Remove all #if 0 and #ifdef __cplusplus blocks.
    	Change all uses of _G_va_list, _G_fpos_t, and _G_fpos64_t to
    	__gnuc_va_list, __fpos_t, __fpos64_t respectively.  Provide
    	definitions of _STDIO_USES_IOSTREAM, __HAVE_COLUMN,
    	_IO_file_flags, __io_read_fn, __io_write_fn, __io_seek_fn,
    	__io_close_fn, _IO_cookie_io_functions_t for the sake of the
    	implementation.  When _IO_USE_OLD_IO_FILE is defined, define
    	struct _IO_FILE_old.
    	* libio/libioP.h: When _IO_USE_OLD_IO_FILE is defined, define
    	struct _IO_FILE_old_plus.
    	* libio/oldfileops.c: Change all uses of _IO_FILE to _IO_FILE_old,
    	_IO_FILE_plus to _IO_FILE_old_plus, _IO_FILE_complete to _IO_FILE,
    	and _IO_FILE_complete_plus to _IO_FILE_plus.
    	* sysdeps/generic/_G_config.h, sysdeps/unix/sysv/linux/_G_config.h:
    	Only provide definition or non-definition of _G_HAVE_MREMAP.
    	* sysdeps/ieee754/ldbl-opt/nldbl-compat.h:
    	Change all uses of _G_va_list to __gnuc_va_list.
    
    	* libio/bits/stdio.h: Add multiple-inclusion guard. Include
    	bits/types/FILE_internals.h. Declare __uflow and __overflow here.
    	Remove redundant __USE_EXTERN_INLINES ifdef.  Change all uses of
    	_G_va_list to __gnuc_va_list and _IO_ssize_t to __ssize_t.
    	(getchar): Use getc, not _IO_getc.
    	(__getc_unlocked, __putc_unlocked): New inlines, duplicating the
    	bodies of _IO_getc_unlocked and	_IO_putc_unlocked.
    	(fgetc_unlocked, getc_unlocked, getchar_unlocked, fread_unlocked):
    	Use __getc_unlocked.
    	(fputc_unlocked, putc_unlocked, putchar_unlocked, fwrite_unlocked):
    	Use __putc_unlocked.
    	(feof_unlocked): Duplicate the body of _IO_feof_unlocked here.
    	(ferror_unlocked): Duplicate the body of _IO_ferror_unlocked here.
    	* libio/bits/stdio2.h: Change all uses of _G_va_list to __gnuc_va_list.
    	(fread_unlocked): Use __getc_unlocked.
    	* libio/bits/types/FILE.h, libio/bits/types/__FILE.h: Explain in
    	comments why the name _IO_FILE is used.
    
    	* include/stdio.h: Change all uses of _G_va_list to __gnuc_va_list,
    	_IO_ssize_t to __size_t, _IO_FILE to FILE, and _IO_fpos_t to __fpos_t.
    	When IS_IN (libc), redirect flockfile and funlockfile to
    	__flockfile and __funlockfile respectively.
    	When _IO_MTSAFE_IO and not _ISOMAC, include stdio-lock.h before
    	stdio.h proper.
    	* include/stdio_ext.h: Include bits/types/FILE_internals.h for the
    	sake of the inline definition of __fsetlocking.
    	* include/libio.h: Adjust #ifdef nest to activate multiple-include
    	optimization.
    	* include/bits/types/FILE_internals.h, include/bits/types/__fpos_t.h
    	* include/bits/types/cookie_io_functions_t.h: New trivial wrappers.
    	* include/bits/stdio.h:	New wrapper; mark __uflow and __overflow
    	as hidden for intra-libc callers.
    
    	* csu/init.c: Include libio.h, not _G_config.h.
    
    	* grp/fgetgrent_r.c, grp/putgrent.c, gshadow/fgetsgent_r.c
    	* gshadow/putsgent.c, misc/getpass.c, misc/getttyent.c
    	* misc/mntent_r.c, posix/getopt.c, pwd/fgetpwent_r.c
    	* shadow/fgetspent_r.c, shadow/putspent.c:
    	Don't include libio/iolibio.h.  Don't redefine flockfile or
    	funlockfile.  Don't use _IO_flockfile or _IO_funlockfile.
    
    	* libio/__fbufsize.c, libio/__flbf.c, libio/__fpending.c
    	* libio/__freadable.c, libio/__freading.c, libio/__fwritable.c
    	* libio/__fwriting.c, malloc/malloc.c: Include libio.h.
    	* misc/err.c: Include libio.h. Don't redefine flockfile or funlockfile.
    
    	* stdio-common/tstgetln.c: Include sys/types.h. Don't redefine ssize_t.
    	* conform/data/stdio.h-data: va_list may be defined as __gnuc_va_list,
    	not _G_va_list.
    	* benchtests/strcoll-inputs/filelist#en_US.UTF-8: Remove _G_config.h.
