This removes unreachable return statements as diagnosed by the -Wunreachable-code patch. Some cases are more obviously an improvement than others - in fact some may get you the idea to replace them with gcc_unreachable () instead, leading to cases of the 'Remove unreachable gcc_unreachable () at the end of functions' patch. 2021-11-25 Richard Biener <rguenther@suse.de> * vec.c (qsort_chk): Do not return the void return value from the noreturn qsort_chk_error. * ccmp.c (expand_ccmp_expr_1): Remove unreachable return. * df-scan.c (df_ref_equal_p): Likewise. * dwarf2out.c (is_base_type): Likewise. (add_const_value_attribute): Likewise. * fixed-value.c (fixed_arithmetic): Likewise. * gimple-fold.c (gimple_fold_builtin_fputs): Likewise. * gimple-ssa-strength-reduction.c (stmt_cost): Likewise. * graphite-isl-ast-to-gimple.c (gcc_expression_from_isl_expr_op): Likewise.
