From 44cb2c9fe5dd2aa8b44eb42f34ec786ba21a2731 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Lureau?= Date: Thu, 10 Dec 2020 17:47:42 +0400 Subject: [PATCH] compiler.h: remove GCC < 3 __builtin_expect fallback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since commit efc6c07 ("configure: Add a test for the minimum compiler version"), QEMU explicitely depends on GCC >= 4.8. (clang >= 3.4 advertizes itself as GCC >= 4.2 compatible and supports __builtin_expect too) Signed-off-by: Marc-André Lureau Message-Id: <20201210134752.780923-4-marcandre.lureau@redhat.com> Signed-off-by: Paolo Bonzini --- include/qemu/compiler.h | 4 ---- 1 file changed, 4 deletions(-) diff --git a/include/qemu/compiler.h b/include/qemu/compiler.h index c76281f354..226ead6c90 100644 --- a/include/qemu/compiler.h +++ b/include/qemu/compiler.h @@ -44,10 +44,6 @@ #endif #ifndef likely -#if __GNUC__ < 3 -#define __builtin_expect(x, n) (x) -#endif - #define likely(x) __builtin_expect(!!(x), 1) #define unlikely(x) __builtin_expect(!!(x), 0) #endif
