tree-loop-distribution.c (const_with_all_bytes_same): New function.
* tree-loop-distribution.c (const_with_all_bytes_same): New function.
(generate_memset_builtin): Only handle integer_all_onesp as -1 val if
TYPE_PRECISION is equal to mode bitsize. Use const_with_all_bytes_same
if possible to compute val.
(classify_partition): Verify CONSTRUCTOR doesn't have any elts.
For QImode integers don't require anything about precision. Use
const_with_all_bytes_same to find out if the constant doesn't have
repeated bytes in it.
* gcc.dg/pr56837.c: New test.
* gcc.dg/tree-ssa/ldist-19.c: Don't check for
"generated memset minus one".
