%M, %S, %U, %w, %W: Give ranges.
%p: Clarify how noon and midnight are handled for AM and PM.
%s: Clarify leap second handling.
%r: Now locale-defined.
%C, %D, %e, %h, %n, %r, %t, %T: Say that they are POSIX.2 extensions.

(mbsinit): Use arg, to pacify GCC -Wall.
1996-09-13 Paul Eggert <eggert@twinsun.com>
* time/strftime.c (strftime):
If using the GNU C library, do not bother to check for
multibyte encodings, since they're safe in formats. Otherwise:
- Check for multibyte encodings when encountering any character that
is not in the basic execution character set of the C Standard.
- Use mbrlen (if available) instead of mblen, to avoid modifying
mblen's internal state.
- Do not assume that '%' cannot appear as the first character of a
multibyte character sequence, since this is possible when not in the
initial shift state.
(HAVE_MBRLEN, MULTIBYTE_IS_FORMAT_SAFE): Define if _LIBC is defined.
(DO_MULTIBYTE): New macro.
(<ctype.h>): Do not include.
(<wchar.h>): Include if HAVE_MBRLEN.
(mbstate_t, mbrlen, mbsinit): Define if ! HAVE_MBRLEN.
(mbstate_zero): New constant.
1996-09-12 Paul Eggert <eggert@twinsun.com>
* time/strftime.c (strftime):
Use an empty zone if it can't be determined; POSIX.2 requires this.
Use plain `int' for pad and modifier (which now contain char value).
Use plain `int' for number_value, to print negative values correctly.
Use plain `int' for digits; there was no need to make it unsigned.
Initialize subfmt consistently.
Remove incorrect code for %EC and %Ey; they aren't implemented yet.
For %O, if there is no alternate digit, output Ascii instead of "".
Output the `%' of an unknown format; this is most likely the right
thing to do if a multibyte string has been misparsed.
Thu Sep 12 23:23:13 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* stdio-common/scanf7.c (main): Remove extra conversion from
printf format string.
Thu Sep 12 23:01:16 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* stdlib/test-canon.c (tests): Rename structure member from errno
to error, all uses changed.

* sysdeps/m68k/fpu/__math.h (__frexp, __frexpf, __frexpl):
Return value must be in [0.5, 1), not [1, 2). Reported by Chris
Lawrence.
(__ilogb, __ilogbf, __ilogbl): Check for argument being zero.
(__scalbn, __scalbnf, __scalbnl): Use second argument directly.
Thu Sep 12 19:59:24 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sysdeps/libm-ieee754/e_acoshl.c: Fix typos.
* sysdeps/libm-ieee754/s_cbrtl.c: Remove unused variable.
Thu Sep 12 19:59:24 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sysdeps/libm-ieee754/e_acoshl.c: Fix typos.

syntax error.
* stdio-common/Makefile: Put lockfile in routines
unconditionally.
Define _MT_SAFE_IO if using for libio and compiling reentrant
libc.
* stdio-common/vfprintf.c (__flockfile, __funlockfile): Declare
this always, not just if _LIBC_REENTRANT.
(__funlockfile): Don't use weak_extern for this one;
__libc_cleanup_region_end might be defined and the use of
__funlockfile can't be protected the way the use of __flockfile
can be.

Add INLINE_SYSCALL_ERROR_RETURN_VALUE
For ia32 PIC, the first thing of many syscalls does is to call
__x86.get_pc_thunk.reg to load PC into reg in case there is an error,
which is required for setting errno. In most cases, there are no
errors. But we still call __x86.get_pc_thunk.reg. This patch adds
INLINE_SYSCALL_ERROR_RETURN_VALUE so that i386 can optimize setting
errno by branching to the internal __syscall_error without PLT.
With i386 INLINE_SYSCALL_ERROR_RETURN_VALUE and i386 syscall inlining
optimization for GCC 5, for sysdeps/unix/sysv/linux/fchmodat.c with
-O2 -march=i686 -mtune=generic, GCC 5.2 now generates:

Add INLINE_SYSCALL_ERROR_RETURN_VALUE
For ia32 PIC, the first thing of many syscalls does is to call
__x86.get_pc_thunk.reg to load PC into reg in case there is an error,
which is required for setting errno. In most cases, there are no
errors. But we still call __x86.get_pc_thunk.reg. This patch adds
INLINE_SYSCALL_ERROR_RETURN_VALUE so that i386 can optimize setting
errno by branching to the internal __syscall_error without PLT.
With i386 INLINE_SYSCALL_ERROR_RETURN_VALUE and i386 syscall inlining
optimization for GCC 5, for sysdeps/unix/sysv/linux/fchmodat.c with
-O2 -march=i686 -mtune=generic, GCC 5.2 now generates:

Add INLINE_SYSCALL_ERROR_RETURN_VALUE
For ia32 PIC, the first thing of many syscalls does is to call
__x86.get_pc_thunk.reg to load PC into reg in case there is an error,
which is required for setting errno. In most cases, there are no
errors. But we still call __x86.get_pc_thunk.reg. This patch adds
INLINE_SYSCALL_ERROR_RETURN_VALUE so that i386 can optimize setting
errno by branching to the internal __syscall_error without PLT.
With i386 INLINE_SYSCALL_ERROR_RETURN_VALUE and i386 syscall inlining
optimization for GCC 5, for sysdeps/unix/sysv/linux/fchmodat.c with
-O2 -march=i686 -mtune=generic, GCC 5.2 now generates:
<fchmodat>:

2 * xchg is more expensive than pushl + movl + popl
|
|
|
|
|
|
|
|
Beside this a neat trick is used. The calling conventions for Linux
|
|
|
|
tell that among the registers used for parameters %ecx and %edx need
|
|
|
|
not be saved. Beside this we may clobber this registers even when
|
|
|
|
they are not used for parameter passing.
|
|
|
|
|
|
|
|
As a result one can see below that we save the content of the %ebx
|
|
|
|
register in the %edx register when we have less than 3 arguments
|
|
|
|
(2 * movl is less expensive than pushl + popl).
|
|
|
|
|
|
|
|
Second unlike for the other registers we don't save the content of
|
1996-10-23 01:29:26 +02:00
|
|
|
%ecx and %edx when we have more than 1 and 2 registers resp.

Add INLINE_SYSCALL_ERROR_RETURN_VALUE
For ia32 PIC, the first thing of many syscalls does is to call
__x86.get_pc_thunk.reg to load PC into reg in case there is an error,
which is required for setting errno. In most cases, there are no
errors. But we still call __x86.get_pc_thunk.reg. This patch adds
INLINE_SYSCALL_ERROR_RETURN_VALUE so that i386 can optimize setting
errno by branching to the internal __syscall_error without PLT.
With i386 INLINE_SYSCALL_ERROR_RETURN_VALUE and i386 syscall inlining
optimization for GCC 5, for sysdeps/unix/sysv/linux/fchmodat.c with
-O2 -march=i686 -mtune=generic, GCC 5.2 now generates:

Support six-argument syscalls from C for 32-bit x86, use generic lowlevellock-futex.h (bug 18138).
This patch follows the approach outlined in
<https://sourceware.org/ml/libc-alpha/2015-03/msg00656.html> to
support six-argument syscalls from INTERNAL_SYSCALL for 32-bit x86,
making them call a function __libc_do_syscall that takes the syscall
number and three syscall arguments in the registers in which the
kernel expects them, along with a pointer to a structure containing
the other three arguments.
In turn, this allows the generic lowlevellock-futex.h to be used on
32-bit x86, so supporting lll_futex_timed_wait_bitset (and so allowing
FUTEX_CLOCK_REALTIME to be used in various cases, so fixing bug 18138
for 32-bit x86 and leaving hppa as the only architecture missing
lll_futex_timed_wait_bitset). The change to lowlevellock.h's
definition of SYS_futex is because the generic lowlevelloc-futex.h
ends up bringing in bits/syscall.h which defines SYS_futex to
__NR_futex, so resulting in redefinition errors. The revised
definition in lowlevellock.h is in line with what the x86_64 version
does.
__libc_do_syscall is only needed in libpthread at present (meaning
nothing special needs to be done to make it shared-only in most
libraries containing it, static in libc only, as on ARM).
Tested for 32-bit x86, with the glibc testsuite and with the test in
bug 18138. The failures seen
FAIL: nptl/tst-cleanupx4
FAIL: rt/tst-cpuclock2
are pre-existing.

Optimize i386 syscall inlining for GCC 5
Since GCC 5 and above can properly spill %ebx when needed, we can inline
syscalls with 6 arguments if GCC 5 or above is used to compile glibc.
This patch rewrites INTERNAL_SYSCALL macros and skips __libc_do_syscall
for GCC 5.
For sysdeps/unix/sysv/linux/i386/brk.c, with -O2 -march=i686
-mtune=generic, GCC 5.2 now generates:
<__brk>:
0: push %ebx
1: mov $0x2d,%eax
6: mov 0x8(%esp),%ebx
a: call b <__brk+0xb> b: R_386_PC32 __x86.get_pc_thunk.dx

Add INLINE_SYSCALL_ERROR_RETURN_VALUE
For ia32 PIC, the first thing of many syscalls does is to call
__x86.get_pc_thunk.reg to load PC into reg in case there is an error,
which is required for setting errno. In most cases, there are no
errors. But we still call __x86.get_pc_thunk.reg. This patch adds
INLINE_SYSCALL_ERROR_RETURN_VALUE so that i386 can optimize setting
errno by branching to the internal __syscall_error without PLT.
With i386 INLINE_SYSCALL_ERROR_RETURN_VALUE and i386 syscall inlining
optimization for GCC 5, for sysdeps/unix/sysv/linux/fchmodat.c with
-O2 -march=i686 -mtune=generic, GCC 5.2 now generates:

Add INLINE_SYSCALL_ERROR_RETURN_VALUE
For ia32 PIC, the first thing of many syscalls does is to call
__x86.get_pc_thunk.reg to load PC into reg in case there is an error,
which is required for setting errno. In most cases, there are no
errors. But we still call __x86.get_pc_thunk.reg. This patch adds
INLINE_SYSCALL_ERROR_RETURN_VALUE so that i386 can optimize setting
errno by branching to the internal __syscall_error without PLT.
With i386 INLINE_SYSCALL_ERROR_RETURN_VALUE and i386 syscall inlining
optimization for GCC 5, for sysdeps/unix/sysv/linux/fchmodat.c with
-O2 -march=i686 -mtune=generic, GCC 5.2 now generates:

#undef INTERNAL_SYSCALL
|
Support six-argument syscalls from C for 32-bit x86, use generic lowlevellock-futex.h (bug 18138).
This patch follows the approach outlined in
<https://sourceware.org/ml/libc-alpha/2015-03/msg00656.html> to
support six-argument syscalls from INTERNAL_SYSCALL for 32-bit x86,
making them call a function __libc_do_syscall that takes the syscall
number and three syscall arguments in the registers in which the
kernel expects them, along with a pointer to a structure containing
the other three arguments.
In turn, this allows the generic lowlevellock-futex.h to be used on
32-bit x86, so supporting lll_futex_timed_wait_bitset (and so allowing
FUTEX_CLOCK_REALTIME to be used in various cases, so fixing bug 18138
for 32-bit x86 and leaving hppa as the only architecture missing
lll_futex_timed_wait_bitset). The change to lowlevellock.h's
definition of SYS_futex is because the generic lowlevelloc-futex.h
ends up bringing in bits/syscall.h which defines SYS_futex to
__NR_futex, so resulting in redefinition errors. The revised
definition in lowlevellock.h is in line with what the x86_64 version
does.
__libc_do_syscall is only needed in libpthread at present (meaning
nothing special needs to be done to make it shared-only in most
libraries containing it, static in libc only, as on ARM).
Tested for 32-bit x86, with the glibc testsuite and with the test in
bug 18138. The failures seen
FAIL: nptl/tst-cleanupx4
FAIL: rt/tst-cpuclock2
are pre-existing.

Optimize i386 syscall inlining for GCC 5
Since GCC 5 and above can properly spill %ebx when needed, we can inline
syscalls with 6 arguments if GCC 5 or above is used to compile glibc.

Support six-argument syscalls from C for 32-bit x86, use generic lowlevellock-futex.h (bug 18138).
This patch follows the approach outlined in
<https://sourceware.org/ml/libc-alpha/2015-03/msg00656.html> to
support six-argument syscalls from INTERNAL_SYSCALL for 32-bit x86,
making them call a function __libc_do_syscall that takes the syscall
number and three syscall arguments in the registers in which the
kernel expects them, along with a pointer to a structure containing
the other three arguments.
In turn, this allows the generic lowlevellock-futex.h to be used on
32-bit x86, so supporting lll_futex_timed_wait_bitset (and so allowing
FUTEX_CLOCK_REALTIME to be used in various cases, so fixing bug 18138
for 32-bit x86 and leaving hppa as the only architecture missing
lll_futex_timed_wait_bitset). The change to lowlevellock.h's
definition of SYS_futex is because the generic lowlevelloc-futex.h
ends up bringing in bits/syscall.h which defines SYS_futex to
__NR_futex, so resulting in redefinition errors. The revised
definition in lowlevellock.h is in line with what the x86_64 version
does.
__libc_do_syscall is only needed in libpthread at present (meaning
nothing special needs to be done to make it shared-only in most
libraries containing it, static in libc only, as on ARM).
Tested for 32-bit x86, with the glibc testsuite and with the test in
bug 18138. The failures seen
FAIL: nptl/tst-cleanupx4
FAIL: rt/tst-cpuclock2
are pre-existing.

Support six-argument syscalls from C for 32-bit x86, use generic lowlevellock-futex.h (bug 18138).
This patch follows the approach outlined in
<https://sourceware.org/ml/libc-alpha/2015-03/msg00656.html> to
support six-argument syscalls from INTERNAL_SYSCALL for 32-bit x86,
making them call a function __libc_do_syscall that takes the syscall
number and three syscall arguments in the registers in which the
kernel expects them, along with a pointer to a structure containing
the other three arguments.
In turn, this allows the generic lowlevellock-futex.h to be used on
32-bit x86, so supporting lll_futex_timed_wait_bitset (and so allowing
FUTEX_CLOCK_REALTIME to be used in various cases, so fixing bug 18138
for 32-bit x86 and leaving hppa as the only architecture missing
lll_futex_timed_wait_bitset). The change to lowlevellock.h's
definition of SYS_futex is because the generic lowlevelloc-futex.h
ends up bringing in bits/syscall.h which defines SYS_futex to
__NR_futex, so resulting in redefinition errors. The revised
definition in lowlevellock.h is in line with what the x86_64 version
does.
__libc_do_syscall is only needed in libpthread at present (meaning
nothing special needs to be done to make it shared-only in most
libraries containing it, static in libc only, as on ARM).
Tested for 32-bit x86, with the glibc testsuite and with the test in
bug 18138. The failures seen
FAIL: nptl/tst-cleanupx4
FAIL: rt/tst-cpuclock2
are pre-existing.

Optimize i386 syscall inlining for GCC 5
Since GCC 5 and above can properly spill %ebx when needed, we can inline
syscalls with 6 arguments if GCC 5 or above is used to compile glibc.

for GCC 5.
For sysdeps/unix/sysv/linux/i386/brk.c, with -O2 -march=i686
-mtune=generic, GCC 5.2 now generates:

Support six-argument syscalls from C for 32-bit x86, use generic lowlevellock-futex.h (bug 18138).
This patch follows the approach outlined in
<https://sourceware.org/ml/libc-alpha/2015-03/msg00656.html> to
support six-argument syscalls from INTERNAL_SYSCALL for 32-bit x86,
making them call a function __libc_do_syscall that takes the syscall
number and three syscall arguments in the registers in which the
kernel expects them, along with a pointer to a structure containing
the other three arguments.
In turn, this allows the generic lowlevellock-futex.h to be used on
32-bit x86, so supporting lll_futex_timed_wait_bitset (and so allowing
FUTEX_CLOCK_REALTIME to be used in various cases, so fixing bug 18138
for 32-bit x86 and leaving hppa as the only architecture missing
lll_futex_timed_wait_bitset). The change to lowlevellock.h's
definition of SYS_futex is because the generic lowlevelloc-futex.h
ends up bringing in bits/syscall.h which defines SYS_futex to
__NR_futex, so resulting in redefinition errors. The revised
definition in lowlevellock.h is in line with what the x86_64 version
does.
__libc_do_syscall is only needed in libpthread at present (meaning
nothing special needs to be done to make it shared-only in most
libraries containing it, static in libc only, as on ARM).
Tested for 32-bit x86, with the glibc testsuite and with the test in
bug 18138. The failures seen
FAIL: nptl/tst-cleanupx4
FAIL: rt/tst-cpuclock2
are pre-existing.

Optimize i386 syscall inlining for GCC 5
Since GCC 5 and above can properly spill %ebx when needed, we can inline
syscalls with 6 arguments if GCC 5 or above is used to compile glibc.
This patch rewrites INTERNAL_SYSCALL macros and skips __libc_do_syscall
for GCC 5.
For sysdeps/unix/sysv/linux/i386/brk.c, with -O2 -march=i686
-mtune=generic, GCC 5.2 now generates:
<__brk>:
0: push %ebx
1: mov $0x2d,%eax
6: mov 0x8(%esp),%ebx
a: call b <__brk+0xb> b: R_386_PC32 __x86.get_pc_thunk.dx

#ifdef OPTIMIZE_FOR_GCC_5

Optimize i386 syscall inlining for GCC 5
Since GCC 5 and above can properly spill %ebx when needed, we can inline
syscalls with 6 arguments if GCC 5 or above is used to compile glibc.
This patch rewrites INTERNAL_SYSCALL macros and skips __libc_do_syscall
for GCC 5.
For sysdeps/unix/sysv/linux/i386/brk.c, with -O2 -march=i686
-mtune=generic, GCC 5.2 now generates:
<__brk>:
0: push %ebx
1: mov $0x2d,%eax
6: mov 0x8(%esp),%ebx
a: call b <__brk+0xb> b: R_386_PC32 __x86.get_pc_thunk.dx
f: add $0x2,%edx 11: R_386_GOTPC _GLOBAL_OFFSET_TABLE_
15: call *%gs:0x10
1c: mov 0x0(%edx),%edx 1e: R_386_GOT32 __curbrk
22: cmp %eax,%ebx
24: mov %eax,(%edx)
26: ja 30 <__brk+0x30>
28: xor %eax,%eax
2a: pop %ebx
2b: ret
instead of
<__brk>:
0: push %ebx
1: mov 0x8(%esp),%ecx
5: call 6 <__brk+0x6> 6: R_386_PC32 __x86.get_pc_thunk.bx
a: add $0x2,%ebx c: R_386_GOTPC _GLOBAL_OFFSET_TABLE_
10: xchg %ecx,%ebx
12: mov $0x2d,%eax
17: call *%gs:0x10
1e: xchg %ecx,%ebx
20: mov %eax,%edx
22: mov 0x0(%ebx),%eax 24: R_386_GOT32 __curbrk
28: mov %edx,(%eax)
2a: xor %eax,%eax
2c: cmp %edx,%ecx
2e: ja 38 <__brk+0x38>
30: pop %ebx
31: ret
The new one is shorter by 2 instructions.

%z: Say that it is a GNU extension.
%Z: Wording fix.
* time/strftime.c: (strftime):
%V: Fix mishandling of week numbers near year boundaries.
%g, %G: New formats (suggested by Arthur David Olson).
%U, %W: Use inline expression instead of `week' function.
%C, %y: Handle negative years portably.
%C, %Y: Use width 1, since values can be arbitrarily wide.

%u: New Posix.2 format.
%w: Width is 1, not 2.

1996-09-13 Paul Eggert <eggert@twinsun.com>
* time/strftime.c (strftime):
If using the GNU C library, do not bother to check for
multibyte encodings, since they're safe in formats. Otherwise:
- Check for multibyte encodings when encountering any character that
is not in the basic execution character set of the C Standard.
- Use mbrlen (if available) instead of mblen, to avoid modifying
mblen's internal state.
- Do not assume that '%' cannot appear as the first character of a
multibyte character sequence, since this is possible when not in the
initial shift state.
(HAVE_MBRLEN, MULTIBYTE_IS_FORMAT_SAFE): Define if _LIBC is defined.
(DO_MULTIBYTE): New macro.
(<ctype.h>): Do not include.
(<wchar.h>): Include if HAVE_MBRLEN.
(mbstate_t, mbrlen, mbsinit): Define if ! HAVE_MBRLEN.
(mbstate_zero): New constant.
1996-09-12 Paul Eggert <eggert@twinsun.com>
* time/strftime.c (strftime):
Use an empty zone if it can't be determined; POSIX.2 requires this.
Use plain `int' for pad and modifier (which now contain char value).
Use plain `int' for number_value, to print negative values correctly.
Use plain `int' for digits; there was no need to make it unsigned.
Initialize subfmt consistently.
Remove incorrect code for %EC and %Ey; they aren't implemented yet.
For %O, if there is no alternate digit, output Ascii instead of "".
Output the `%' of an unknown format; this is most likely the right
thing to do if a multibyte string has been misparsed.
