PR middle-end/97631 - bogus "writing one too many bytes" warning for memcpy with strlen argument
gcc/ChangeLog:
PR middle-end/97631
* tree-ssa-strlen.c (maybe_warn_overflow): Test rawmem.
(handle_builtin_stxncpy_strncat): Rename locals. Determine
destination size from allocation calls. Issue a more appropriate
kind of warning.
(handle_builtin_memcpy): Pass true as rawmem to maybe_warn_overflow.
(handle_builtin_memset): Same.
gcc/testsuite/ChangeLog:
