From 3167423f079e08f530df30eccad2a467c8ad5014 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 29 Jun 2021 20:33:14 -0400 Subject: [PATCH] sim: use -Wno-error=maybe-uninitialized We have some code tripping this warning, but it depends on the gcc version & optimization levels. We've added some hints to the code so some versions of gcc work better, but still not all. Let's just disable the warning like gdb does. --- sim/ChangeLog | 5 +++++ sim/configure | 1 + sim/m4/sim_ac_option_warnings.m4 | 3 +++ 3 files changed, 9 insertions(+) diff --git a/sim/ChangeLog b/sim/ChangeLog index d63e656cb33..959d3582da1 100644 --- a/sim/ChangeLog +++ b/sim/ChangeLog @@ -1,3 +1,8 @@ +2021-06-29 Mike Frysinger + + * m4/sim_ac_option_warnings.m4: Add -Wno-error=maybe-uninitialized. + * configure: Regenerate. + 2021-06-27 Mike Frysinger * arch-subdir.mk.in: Move TERMCAP and READLINE variables from diff --git a/sim/configure b/sim/configure index 34cd1c9e8a2..3120006e6d5 100755 --- a/sim/configure +++ b/sim/configure @@ -14588,6 +14588,7 @@ build_warnings="-Wall -Wdeclaration-after-statement -Wpointer-arith \ -Wpointer-sign \ -Wno-unused -Wunused-value -Wunused-function \ -Wno-switch -Wno-char-subscripts -Wmissing-prototypes +-Wno-error=maybe-uninitialized -Wdeclaration-after-statement -Wempty-body -Wmissing-parameter-type \ -Wold-style-declaration -Wold-style-definition" diff --git a/sim/m4/sim_ac_option_warnings.m4 b/sim/m4/sim_ac_option_warnings.m4 index 5a0fe304e9c..05c77f1b92d 100644 --- a/sim/m4/sim_ac_option_warnings.m4 +++ b/sim/m4/sim_ac_option_warnings.m4 @@ -35,10 +35,13 @@ if test "${ERROR_ON_WARNING}" = yes ; then WERROR_CFLAGS="-Werror" fi +dnl The options we'll try to enable. +dnl NB: Kept somewhat in sync with gdbsupport/warnings.m4. build_warnings="-Wall -Wdeclaration-after-statement -Wpointer-arith \ -Wpointer-sign \ -Wno-unused -Wunused-value -Wunused-function \ -Wno-switch -Wno-char-subscripts -Wmissing-prototypes +-Wno-error=maybe-uninitialized -Wdeclaration-after-statement -Wempty-body -Wmissing-parameter-type \ -Wold-style-declaration -Wold-style-definition" -- 2.30.2
