From b11d029b0a093e31ae13e4fade03c7848e8af169 Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Tue, 9 Feb 2016 11:49:48 -0700 Subject: [PATCH] build: Don't redefine 'inline' Actively redefining 'inline' is wrong for C++, where gcc has an extension 'inline namespace' which fails to compile if the keyword 'inline' is replaced by a macro expansion. This will matter once we start to include "qemu/osdep.h" first from C++ files, depending also on whether the system headers are new enough to be using the gcc extension. But rather than just guard things by __cplusplus, let's look at the overall picture. Commit df2542c737ea2 in 2007 defined 'inline' to the gcc attribute __always_inline__, with the rationale "To avoid discarded inlining bug". But compilers have improved since then, and we are probably better off trusting the compiler rather than trying to force its hand. So just nuke our craziness.
