From 84b7ca80d79f8cfad36e1ef86ca2d9b355ffccd5 Mon Sep 17 00:00:00 2001 From: Ralph Giles Date: Wed, 4 May 2011 23:19:38 -0700 Subject: [PATCH] Mark valgrind's _qzz_res as unused to silence warnings on gcc 4.6. This applies c11675 by Julian Seward from valgrind trunk (svn://svn.valgrind.org/valgrind/trunk) to rustrt's included copies of memcheck.h and valgrind.h, effectively backporting the fix from the unreleased 3.6.2. The commit simply applies the gcc 'unused' attribute to the relevant declarations. This change allows compilation of the runtime code under gcc 4.6 with -Werror, as the makefile currently requests. --- src/rt/memcheck.h | 8 ++++---- src/rt/valgrind.h | 28 ++++++++++++++-------------- 2 files changed, 18 insertions(+), 18 deletions(-) diff --git a/src/rt/memcheck.h b/src/rt/memcheck.h index bf95491b9b8cf..58480256e19dc 100644 --- a/src/rt/memcheck.h +++ b/src/rt/memcheck.h @@ -184,7 +184,7 @@ typedef /* Do a full memory leak check (like --leak-check=full) mid-execution. */ #define VALGRIND_DO_LEAK_CHECK \ - {unsigned long _qzz_res; \ + {unsigned long _qzz_res __attribute((unused)); \ VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ VG_USERREQ__DO_LEAK_CHECK, \ 0, 0, 0, 0, 0); \ @@ -192,7 +192,7 @@ typedef /* Do a summary memory leak check (like --leak-check=summary) mid-execution. */ #define VALGRIND_DO_QUICK_LEAK_CHECK \ - {unsigned long _qzz_res; \ + {unsigned long _qzz_res __attribute((unused)); \ VALGRIND_DO_CLIENT_REQUEST(_qzz_res, 0, \ VG_USERREQ__DO_LEAK_CHECK, \ 1, 0, 0, 0, 0); \ @@ -207,7 +207,7 @@ typedef are.
