-Subject: [PATCH] Fix i686 memchr overflow calculation (BZ#21182)
-
-This patch fixes the regression added by 23d2770 for final address
-overflow calculation.  The subtraction of the considered size (16)
-at line 120 is at wrong place, for sizes less than 16 subsequent
-overflow check will not take in consideration an invalid size (since
-the subtraction will be negative).  Also, the lea instruction also
-does not raise the carry flag (CF) that is used in subsequent jbe
-to check for overflow.
-
-The fix is to follow x86_64 logic from 3daef2c where the overflow
-is first check and a sub instruction is issued.  In case of resulting
-negative size, CF will be set by the sub instruction and a NULL
-result will be returned.  The patch also add similar tests reported
-in bug report.
-
-Checked on i686-linux-gnu and x86_64-linux-gnu.

-	* string/test-memchr.c (do_test): Add BZ#21182 checks for address
-	near end of a page.
-	* sysdeps/i386/i686/multiarch/memchr-sse2.S (__memchr): Fix
-	overflow calculation.
