From 4d8015639a750aacd899e293bceeabb15bde9803 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Tue, 5 Feb 2019 18:32:03 -0200 Subject: wcsmbs: optimize wcscpy This patch rewrites wcscpy using wcslen and wmemcpy. This is similar to the optimization done on strcpy by b863d2bc4d. Checked on x86_64-linux-gnu. * wcsmbs/wcscpy.c (__wcpcpy): Rewrite using wcslen and wmemcpy. --- wcsmbs/wcscpy.c | 31 +------------------------------ 1 file changed, 1 insertion(+), 30 deletions(-) (limited to 'wcsmbs') diff --git a/wcsmbs/wcscpy.c b/wcsmbs/wcscpy.c index 636bf6bd01..6fb2969513 100644 --- a/wcsmbs/wcscpy.c +++ b/wcsmbs/wcscpy.c @@ -16,7 +16,6 @@ License along with the GNU C Library; if not, see . */ -#include #include @@ -28,35 +27,7 @@ wchar_t * __wcscpy (wchar_t *dest, const wchar_t *src) { - wint_t c; - wchar_t *wcp; - - if (__alignof__ (wchar_t) >= sizeof (wchar_t)) - { - const ptrdiff_t off = dest - src - 1; - - wcp = (wchar_t *) src; - - do - { - c = *wcp++; - wcp[off] = c; - } - while (c != L'\0'); - } - else - { - wcp = dest; - - do - { - c = *src++; - *wcp++ = c; - } - while (c != L'\0'); - } - - return dest; + return __wmemcpy (dest, src, __wcslen (src) + 1); } #ifndef WCSCPY weak_alias (__wcscpy, wcscpy) -- cgit v1.2.3
