From 9e6f803254cbf3f5f491775debdc6593c3329da8 Mon Sep 17 00:00:00 2001 From: Andreas Sandberg Date: Wed, 11 Feb 2015 10:23:24 -0500 Subject: base: Add compiler macros to add deprecation warnings Gcc and clang both provide an attribute that can be used to flag a function as deprecated at compile time. This changeset adds a gem5 compiler macro for that compiler feature. The macro can be used to indicate that a legacy API within gem5 has been deprecated and provide a graceful migration to the new API. --- src/base/compiler.hh | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/base') diff --git a/src/base/compiler.hh b/src/base/compiler.hh index b1fea055c..1a104dd87 100644 --- a/src/base/compiler.hh +++ b/src/base/compiler.hh @@ -80,6 +80,8 @@ # define M5_VAR_USED __attribute__((unused)) # define M5_ATTR_PACKED __attribute__ ((__packed__)) # define M5_NO_INLINE __attribute__ ((__noinline__)) +# define M5_DEPRECATED __attribute__((deprecated)) +# define M5_DEPRECATED_MSG(MSG) __attribute__((deprecated(MSG))) #endif #if defined(__clang__) -- cgit v1.2.3
