From de1c3ebb59c9e9f7caaf5a71920fe613e3e7cfaa Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 15 Sep 2007 02:38:04 +0000 Subject: * misc/sys/cdefs.h (__va_arg_pack): Define for GCC 4.3+. * misc/bits/syslog.h (syslog): When __va_arg_pack is defined, implement as __extern_always_inline function. (vsyslog): Define as __extern_always_inline function unconditionally. * libio/bits/stdio2.h (sprintf, snprintf, printf, fprintf): When __va_arg_pack is defined, implement as __extern_always_inline functions. (vsprintf, vsnprintf, vprintf, vfprintf): Define as __extern_always_inline functions unconditionally. * libio/bits/stdio.h (vprintf): Ifdef out the inline when bits/stdio2.h will be included. * wcsmbs/bits/wchar2.h (__swprintf_alias): New redirect. (swprintf, wprintf, fwprintf): When __va_arg_pack is defined, implement as __extern_always_inline functions. (vswprintf, vwprintf, vfwprintf): Define as __extern_always_inline functions unconditionally. * debug/tst-chk1.c (do_test): Enable remaining tests for C++. 2007-09-03 Jakub Jelinek * misc/sys/cdefs.h (__extern_inline, __extern_always_inline): Only define in C++ for GCC 4.3+, in C++ always use __gnu_inline__ attribute. * include/features.h (__USE_EXTERN_INLINES): Define only when __extern_inline is defined. * stdlib/stdlib.h: Include bits/stdlib.h when __extern_always_inline is defined instead of when not __cplusplus. * misc/sys/syslog.h: Include bits/syslog.h when __extern_always_inline is defined instead of when not __cplusplus. * socket/sys/socket.h: Include bits/socket2.h when __extern_always_inline is defined instead of when not __cplusplus. * libio/stdio.h: Include bits/stdio2.h when __extern_always_inline is defined instead of when not __cplusplus. * posix/unistd.h: Include bits/unistd.h when __extern_always_inline is defined instead of when not __cplusplus. * string/string.h: Include bits/string3.h when __extern_always_inline is defined instead of when not __cplusplus. * wcsmbs/wchar.h: Include bits/wchar2.h when __extern_always_inline is defined instead of when not __cplusplus. (btowc, wctob): Don't guard the inlines with ifndef __cplusplus. * io/fcntl.h: Don't include bits/fcntl2.h if __extern_always_inline is not defined. * misc/bits/syslog-ldbl.h: Guard *_chk stuff with defined __extern_always_inline instead of !defined __cplusplus. * libio/bits/stdio-ldbl.h: Likewise. * wcsmbs/bits/wchar-ldbl.h: Likewise. * misc/bits/syslog.h (syslog): Don't define for C++. (vsyslog): Use __extern_always_inline function for C++ instead of a macro. * libio/bits/stdio.h (__STDIO_INLINE): Define to __extern_inline whenever that macro is defined. (vprintf): Don't provide the inline for C++. (fread_unlocked, fwrite_unlocked): Don't define the macros for C++. * libio/bits/stdio2.h (sprintf, snprintf, printf, fprintf): Don't define the macros for C++. (vsprintf, vsnprintf, vprintf, vfprintf): Define as __extern_always_inline functions for C++. * io/sys/stat.h (stat, lstat, fstat, fstatat, mknod, mknodat, stat64, lstat64, fstat64, fstatat64): Don't define if not __USE_EXTERN_INLINES. * wcsmbs/bits/wchar2.h: Fix #error message. (swprintf, wprintf, fwprintf): Don't define the macros for C++. (vswprintf, vwprintf, vfwprintf): Define using __extern_always_inline functions for C++. * string/bits/string3.h: Don't #undef macros if __cplusplus. (memcpy, memmove, mempcpy, memset, bcopy, bzero, strcpy, stpcpy, strncpy, strcat, strncat): Define as __extern_always_inline functions instead of macros for C++. * math/bits/cmathcalls.h: Guard __extern_inline routines with defined __extern_inline. * sysdeps/alpha/fpu/bits/mathinline.h (__MATH_INLINE): Define to __extern_inline whenever that macro is defined. * sysdeps/ia64/fpu/bits/mathinline.h (__MATH_INLINE): Likewise. * sysdeps/i386/fpu/bits/mathinline.h (__MATH_INLINE): Likewise. * sysdeps/i386/i486/bits/string.h (__STRING_INLINE): Likewise. * sysdeps/s390/bits/string.h (__STRING_INLINE): Likewise. * sysdeps/s390/fpu/bits/mathinline.h (__MATH_INLINE): Likewise. * sysdeps/powerpc/fpu/bits/mathinline.h (__MATH_INLINE): Likewise. * sysdeps/x86_64/fpu/bits/mathinline.h (__MATH_INLINE): Likewise. * sysdeps/sparc/fpu/bits/mathinline.h (__MATH_INLINE): Likewise. * sysdeps/unix/sysv/linux/sys/sysmacros.h (gnu_dev_major, gnu_dev_minor, gnu_dev_makedev): Remove __extern_inline from prototypes. Only provide __extern_inline routines if __USE_EXTERN_INLINES. * debug/Makefile: Add rules to build and run tst-{,lfs}chk{4,5,6} tests. * debug/tst-chk1.c (do_prepare, do_test): Allow compilation as C++. For now avoid some *printf tests in C++. Skip all testing if __USE_FORTIFY_LEVEL is defined, but __extern_always_inline macro is not. * debug/tst-chk4.cc: New file. * debug/tst-chk5.cc: New file. * debug/tst-chk6.cc: New file. * debug/tst-lfschk4.cc: New file. * debug/tst-lfschk5.cc: New file. * debug/tst-lfschk6.cc: New file. * include/wchar.h (__vfwprintf_chk, __vswprintf_chk): Avoid prototypes in C++. * include/stdio.h (__sprintf_chk, __snprintf_chk, __vsprintf_chk, __vsnprintf_chk, __printf_chk, __fprintf_chk, __vprintf_chk, __vfprintf_chk, __fgets_unlocked_chk, __fgets_chk): Likewise. --- include/features.h | 3 ++- include/stdio.h | 2 ++ include/wchar.h | 2 ++ 3 files changed, 6 insertions(+), 1 deletion(-) (limited to 'include') diff --git a/include/features.h b/include/features.h index 7f99741a95..18f743cb75 100644 --- a/include/features.h +++ b/include/features.h @@ -341,7 +341,8 @@ /* Decide whether we can define 'extern inline' functions in headers. */ #if __GNUC_PREREQ (2, 7) && defined __OPTIMIZE__ \ - && !defined __OPTIMIZE_SIZE__ && !defined __NO_INLINE__ + && !defined __OPTIMIZE_SIZE__ && !defined __NO_INLINE__ \ + && defined __extern_inline # define __USE_EXTERN_INLINES 1 #endif diff --git a/include/stdio.h b/include/stdio.h index 748523d4d1..84b8af9da1 100644 --- a/include/stdio.h +++ b/include/stdio.h @@ -27,6 +27,7 @@ extern int __vsscanf (__const char *__restrict __s, _G_va_list __arg) __attribute__ ((__format__ (__scanf__, 2, 0))); +#ifndef __cplusplus extern int __sprintf_chk (char *, int, size_t, const char *, ...) __THROW; extern int __snprintf_chk (char *, size_t, int, size_t, const char *, ...) __THROW; @@ -40,6 +41,7 @@ extern int __vprintf_chk (int, const char *, _G_va_list); extern int __vfprintf_chk (FILE *, int, const char *, _G_va_list); extern char *__fgets_unlocked_chk (char *buf, size_t size, int n, FILE *fp); extern char *__fgets_chk (char *buf, size_t size, int n, FILE *fp); +#endif /* Prototypes for compatibility functions. */ extern FILE *__new_tmpfile (void); diff --git a/include/wchar.h b/include/wchar.h index b5f74da0f0..7651f6de29 100644 --- a/include/wchar.h +++ b/include/wchar.h @@ -152,6 +152,7 @@ extern int __vfwprintf (__FILE *__restrict __s, __const wchar_t *__restrict __format, __gnuc_va_list __arg) /* __attribute__ ((__format__ (__wprintf__, 2, 0))) */; +#ifndef __cplusplus extern int __vfwprintf_chk (FILE *__restrict __s, int __flag, const wchar_t *__restrict __format, __gnuc_va_list __arg) @@ -163,6 +164,7 @@ extern int __vswprintf_chk (wchar_t *__restrict __s, size_t __n, /* __attribute__ ((__format__ (__wprintf__, 5, 0))) */; libc_hidden_proto (__vfwprintf_chk) libc_hidden_proto (__vswprintf_chk) +#endif /* Internal functions. */ extern size_t __mbsrtowcs_l (wchar_t *dst, const char **src, size_t len, -- cgit 1.4.1
