From aff689d36d66dd45a59008f3778d3d22e3cfcb9b Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Sat, 21 Apr 2018 12:00:29 -0600 Subject: [PATCH] Add -Wduplicated-cond This adds -Wduplicated-cond to warnings.m4. This caught one bug. I tried adding -Wduplicated-branches as well, but it results in some spurious failures from code like this in cgen.h: #define CGEN_ATTR_TYPE(n) \ struct { unsigned int bool_; \ CGEN_ATTR_VALUE_TYPE nonbool[(n) ? (n) : 1]; } This will trigger a warning if passed n==1, which seems like a perfectly valid thing to do; and there were other issues like this as well.
