From c02332052959e4213a59ce0ff40354f51506103a Mon Sep 17 00:00:00 2001 From: Mark Wielaard Date: Wed, 6 Jul 2011 23:07:51 +0200 Subject: [PATCH] Silence sys/sdt.h comparison of unsigned expression < 0 is always false. Some arm g++ setups would complain about the wchar_t "signedness detection": sys/sdt.h:102: error: comparison of unsigned expression < 0 is always false jistone said: "((T)(-1) < 1)" would still get the right boolean value, and shouldn't trigger range errors like "unsigned is never < 0". --- includes/sys/sdt.h | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/includes/sys/sdt.h b/includes/sys/sdt.h index f7e1360..0a9fd40 100644 --- a/includes/sys/sdt.h +++ b/includes/sys/sdt.h @@ -77,7 +77,7 @@ struct __sdt_type #define __SDT_ALWAYS_SIGNED(T) \ template<> struct __sdt_type { static const bool __sdt_signed = true; }; #define __SDT_COND_SIGNED(T) \ -template<> struct __sdt_type { static const bool __sdt_signed = ((T)(-1) < 0); }; +template<> struct __sdt_type { static const bool __sdt_signed = ((T)(-1) < 1); }; __SDT_ALWAYS_SIGNED(signed char) __SDT_ALWAYS_SIGNED(short) __SDT_ALWAYS_SIGNED(int) -- 1.7.3.4
