From 16507dea753527d073f1cfb7200c6612a7fa44aa Mon Sep 17 00:00:00 2001 From: Richard Biener Date: Wed, 24 Nov 2021 15:57:03 +0100 Subject: Remove unreachable returns 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 * 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.
