Question about fold C_MAYBE_CONST_EXPR expressions

Hi, I ran into a problem that C frontend (in function build_conditional_expr) creates expression like (C_MAYBE_CONST_EXPR (NULL, x + const)). The inner expression (and its operands) have unsigned int type. After that, the expression needs to be casted to result type which is unsigned short. In t

possibly dead call from slsr_process_phi () to gimple_bb ()

Hi, I am trying to write a WIP patch to warn for dead function calls, and incidentally it caught the following dead call to gimple_bb() from slsr_process_phi () in gimple-ssa-strength-reduction.c: if (SSA_NAME_IS_DEFAULT_DEF (arg)) arg_bb = single_succ (ENTRY_BLOCK_PTR_FOR_FN (cfun)); else
