re PR rtl-optimization/85376 (wrong code with -Og -fno-dce -fgcse -fno-tree-ccp -fno-tree-copy-prop)
PR rtl-optimization/85376
* simplify-rtx.c (simplify_const_unary_operation): For CLZ and CTZ and
zero op0, if C?Z_DEFINED_VALUE_AT_ZERO is false, return NULL_RTX
instead of a specific value.
* gcc.dg/pr85376.c: New test.
