*	Fix x86 strncat optimized implementation for large sizes	Adhemerval Zanella	2017-01-03	1	-0/+15
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Similar to BZ#19387, BZ#21014, and BZ#20971, both x86 sse2 strncat optimized assembly implementations do not handle the size overflow correctly. The x86_64 one is in fact an issue with strcpy-sse2-unaligned, but that is triggered also with strncat optimized implementation. This patch uses a similar strategy used on 3daef2c8ee4df2, where saturared math is used for overflow case. Checked on x86_64-linux-gnu and i686-linux-gnu. It fixes BZ #19390. [BZ #19390] * string/test-strncat.c (test_main): Add tests with SIZE_MAX as maximum string size. * sysdeps/i386/i686/multiarch/strcat-sse2.S (STRCAT): Avoid overflow in pointer addition. * sysdeps/x86_64/multiarch/strcpy-sse2-unaligned.S (STRCPY): Likewise.
