Subject: [TESTSUITE]Use memcpy instead of strcpy in testsuite/gcc.dg/memcmp-1.c
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3aebc597181a97c7b064f04d8e8aa30f79c51451;p=gcc.git

[TESTSUITE]Use memcpy instead of strcpy in testsuite/gcc.dg/memcmp-1.c

strcpy will keep reading and writing memory if the string is not terminated
with null character. In this case, it may visit memory beyond the boundary.
