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. --- elf/dl-load.c | 39 +++++++++++++++++++-------------------- 1 file changed, 19 insertions(+), 20 deletions(-) (limited to 'elf/dl-load.c') diff --git a/elf/dl-load.c b/elf/dl-load.c index 9a6aae6a93..0b752676b7 100644 --- a/elf/dl-load.c +++ b/elf/dl-load.c @@ -238,12 +238,12 @@ fillin_rpath (char *rpath, struct r_search_path_elem **result, const char *sep, if (tmp == NULL) _dl_signal_error (ENOMEM, NULL, "cannot create cache for search path"); - memcpy (tmp, cp, len); - memcpy (tmp + len, _dl_platform, _dl_platformlen); - tmp[len + _dl_platformlen] = '/'; - tmp[len + _dl_platformlen + 1] = '\0'; - dirp->dirname = tmp; + tmp = __mempcpy (tmp, cp, len); + tmp = __mempcpy (tmp, _dl_platform, _dl_platformlen); + *tmp++ = '/'; + *tmp = '\0'; + dirp->machdirstatus = dirp->dirstatus; if (max_dirnamelen < dirp->machdirnamelen) @@ -260,13 +260,11 @@ fillin_rpath (char *rpath, struct r_search_path_elem **result, const char *sep, if (tmp == NULL) _dl_signal_error (ENOMEM, NULL, "cannot create cache for search path"); - memcpy (tmp, cp, len); - tmp[len] = '\0'; + dirp->dirname = tmp; + *((char *) __mempcpy (tmp, cp, len)) = '\0'; if (max_dirnamelen < dirp->dirnamelen) max_dirnamelen = dirp->dirnamelen; - - dirp->dirname = tmp; } dirp->next = all_dirs; @@ -430,12 +428,11 @@ _dl_init_paths (void) _dl_signal_error (ENOMEM, NULL, "cannot create cache for search path"); - memcpy (tmp, relem->dirname, relem->dirnamelen); - memcpy (tmp + relem->dirnamelen, _dl_platform, _dl_platformlen); - tmp[relem->dirnamelen + _dl_platformlen] = '/'; - tmp[relem->dirnamelen + _dl_platformlen + 1] = '\0'; - relem->dirname = tmp; + tmp = __mempcpy (tmp, relem->dirname, relem->dirnamelen); + tmp = __mempcpy (tmp, _dl_platform, _dl_platformlen); + *tmp++ = '/'; + *tmp = '\0'; relem->machdirstatus = unknown; @@ -812,9 +809,10 @@ open_path (const char *name, size_t namelen, if (this_dir->machdirstatus != nonexisting) { /* Construct the pathname to try. */ - (void) memcpy (buf, this_dir->dirname, this_dir->machdirnamelen); - (void) memcpy (buf + this_dir->machdirnamelen, name, namelen); - buflen = this_dir->machdirnamelen + namelen; + buflen = ((char *) __mempcpy (__mempcpy (buf, this_dir->dirname, + this_dir->machdirnamelen), + name, namelen) + - buf); fd = __open (buf, O_RDONLY); if (this_dir->machdirstatus == unknown) @@ -839,9 +837,10 @@ open_path (const char *name, size_t namelen, if (fd == -1 && this_dir->dirstatus != nonexisting) { /* Construct the pathname to try. */ - (void) memcpy (buf, this_dir->dirname, this_dir->dirnamelen); - (void) memcpy (buf + this_dir->dirnamelen, name, namelen); - buflen = this_dir->dirnamelen + namelen; + buflen = ((char *) __mempcpy (__mempcpy (buf, this_dir->dirname, + this_dir->dirnamelen), + name, namelen) + - buf); fd = __open (buf, O_RDONLY); if (this_dir->dirstatus == unknown) -- cgit v1.2.3
