(struct toktab): Make tokstr field a const char *. * elf/dl-profile.c: Fix typo. * inet/ether_ntoh.c: Don't use relative #include path. * inet/gethstbynm.c: Likewise. * resolv/inet_pton.c: Likewise. * shadow/sgetspent_r.c: Likewise. * libio/oldfileops.c (_IO_old_file_jumps): Use correct sync and write callbacks. Patch by NIIBE Yutaka . * posix/confstr.c: Correct string for _CS_LFS_CFLAGS. Handle _CS_XBS5_* constants. * posix/unistd.h: Add comment describing _XBS5_* constants. * sysdeps/generic/bits/confname.h: Add _CS_XBS5_* constants. * posix/regex.c: Indent preprocessor code. * posix/wordexp.c: Using _itoa_word instead of sprintf. * stdlib/canonicalize.c: Avoid unnecessary copying. Handle NULL and "" arguments correctly according to SUS. * stdlib/test-canon.c: Test "" and NULL argument handling. * sysdeps/posix/writev.c: Correct condition to leave the loop. 1997-11-05 18:13 Ulrich Drepper * nss/getXXbyYY.c: Set buffer to NULL if realloc fails so that possible next call starts with malloc again. Proposed by Joe Keane . 1997-11-04 23:57 Ulrich Drepper * configure.in: Correct gcc -pipe test. Patch by Zack Weinberg . * posix/glob.c: Cleanups. Patch by H.J. Lu . 1997-11-04 Andreas Jaeger * manual/creature.texi (Feature Test Macros): Add _POSIX_C_SOURCE definition. --- libio/fileops.c | 11 ++++++++++- libio/genops.c | 18 +++++++++++++++++- libio/obprintf.c | 5 +---- libio/oldfileops.c | 4 ++-- 4 files changed, 30 insertions(+), 8 deletions(-) (limited to 'libio') diff --git a/libio/fileops.c b/libio/fileops.c index e82e2b3..ffc57f1 100644 --- a/libio/fileops.c +++ b/libio/fileops.c @@ -706,7 +706,12 @@ _IO_file_xsputn (f, data, n) count = to_do; if (count > 20) { +#ifdef _LIBC + f->_IO_write_ptr = __mempcpy (f->_IO_write_ptr, s, count); +#else memcpy (f->_IO_write_ptr, s, count); + f->_IO_write_ptr += count; +#endif s += count; } else @@ -715,8 +720,8 @@ _IO_file_xsputn (f, data, n) register int i = (int) count; while (--i >= 0) *p++ = *s++; + f->_IO_write_ptr = p; } - f->_IO_write_ptr += count; to_do -= count; } if (to_do + must_flush > 0) @@ -765,8 +770,12 @@ _IO_file_xsgetn (fp, data, n) count = more; if (count > 20) { +#ifdef _LIBC + s = __mempcpy (s, fp->_IO_read_ptr, count); +#else memcpy (s, fp->_IO_read_ptr, count); s += count; +#endif fp->_IO_read_ptr += count; } else if (count <= 0) diff --git a/libio/genops.c b/libio/genops.c index 20d0df2..3776b9e 100644 --- a/libio/genops.c +++ b/libio/genops.c @@ -210,12 +210,20 @@ save_for_backup (fp) return EOF; /* FIXME */ if (least_mark < 0) { +#ifdef _LIBC + __mempcpy (__mempcpy (new_buffer + avail, + fp->_IO_save_end + least_mark, + -least_mark), + fp->_IO_read_base, + fp->_IO_read_end - fp->_IO_read_base); +#else memcpy (new_buffer + avail, fp->_IO_save_end + least_mark, -least_mark); memcpy (new_buffer + avail - least_mark, fp->_IO_read_base, fp->_IO_read_end - fp->_IO_read_base); +#endif } else memcpy (new_buffer + avail, @@ -368,9 +376,13 @@ _IO_default_xsputn (f, data, n) count = more; if (count > 20) { +#ifdef _LIBC + f->_IO_write_ptr = __mempcpy (f->_IO_write_ptr, s, count); +#else memcpy (f->_IO_write_ptr, s, count); - s += count; f->_IO_write_ptr += count; +#endif + s += count; } else if (count <= 0) count = 0; @@ -419,8 +431,12 @@ _IO_default_xsgetn (fp, data, n) count = more; if (count > 20) { +#ifdef _LIBC + s = __mempcpy (s, fp->_IO_read_ptr, count); +#else memcpy (s, fp->_IO_read_ptr, count); s += count; +#endif fp->_IO_read_ptr += count; } else if (count <= 0) diff --git a/libio/obprintf.c b/libio/obprintf.c index a0c4df6..a4d685a 100644 --- a/libio/obprintf.c +++ b/libio/obprintf.c @@ -80,10 +80,7 @@ _IO_obstack_xsputn (_IO_FILE *fp, const void *data, _IO_size_t n) obstack_blank_fast (obstack, fp->_IO_write_end - fp->_IO_write_ptr); } else - { - memcpy (fp->_IO_write_ptr, data, n); - fp->_IO_write_ptr += n; - } + fp->_IO_write_ptr = __mempcpy (fp->_IO_write_ptr, data, n); return n; } diff --git a/libio/oldfileops.c b/libio/oldfileops.c index ab4445c..71a2bc2 100644 --- a/libio/oldfileops.c +++ b/libio/oldfileops.c @@ -707,10 +707,10 @@ struct _IO_jump_t _IO_old_file_jumps = JUMP_INIT(seekoff, _IO_old_file_seekoff), JUMP_INIT(seekpos, _IO_default_seekpos), JUMP_INIT(setbuf, _IO_old_file_setbuf), - JUMP_INIT(sync, _IO_file_sync), + JUMP_INIT(sync, _IO_old_file_sync), JUMP_INIT(doallocate, _IO_file_doallocate), JUMP_INIT(read, _IO_file_read), - JUMP_INIT(write, _IO_file_write), + JUMP_INIT(write, _IO_old_file_write), JUMP_INIT(seek, _IO_file_seek), JUMP_INIT(close, _IO_file_close), JUMP_INIT(stat, _IO_file_stat) -- cgit v1.1
