Subject: [kvm-unit-tests GIT PULL 11/11] s390x: fix inline asm on gcc10
Date: Fri, 31 Jul 2020 11:46:07 +0200	[thread overview]
Message-ID: <20200731094607.15204-12-frankja@linux.ibm.com> (raw)
In-Reply-To: <20200731094607.15204-1-frankja@linux.ibm.com>

From: Claudio Imbrenda <imbrenda@linux.ibm.com>

Fix compilation issues on 390x with gcc 10.

Simply mark the inline functions that lead to a .insn with a variable
opcode as __always_inline, to make gcc 10 happy.
