Adhemerval Zanella 3abeeec5f4 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.		2017-03-29 09:54:14 -03:00
