From d73415a315471ac0b127ed3fad45c8ec5d711de1 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Wed, 23 Sep 2020 11:56:46 +0100 Subject: qemu/atomic.h: rename atomic_ to qatomic_ MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit clang's C11 atomic_fetch_*() functions only take a C11 atomic type pointer argument. QEMU uses direct types (int, etc) and this causes a compiler error when a QEMU code calls these functions in a source file that also included via a system header file: $ CC=clang CXX=clang++ ./configure ... && make ../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid) Avoid using atomic_*() names in QEMU's atomic.h since that namespace is used by . Prefix QEMU's APIs with 'q' so that atomic.h and can co-exist. I checked /usr/include on my machine and searched GitHub for existing "qatomic_" users but there seem to be none. This patch was generated using: $ git grep -h -o '\/tmp/changed_identifiers $ for identifier in $(%q$identifier%g" \ $(git grep -I -l "\<$identifier\>") done I manually fixed line-wrap issues and misaligned rST tables.
