PR tree-optimization/83075 - Invalid strncpy optimization
gcc/ChangeLog:
PR tree-optimization/83075
* tree-ssa-strlen.c (handle_builtin_stxncpy): Avoid assuming
strncat/strncpy don't change length of source string.
gcc/testsuite/ChangeLog:
PR tree-optimization/83075
* gcc.dg/tree-ssa/strncat.c: New test.
* gcc.dg/tree-ssa/strncpy-2.c: Same.
