Subject: [PATCH v2 0/2] xen/arm: gnttab: macros modifications
Date: Fri, 6 May 2022 11:42:23 +0200 [thread overview]
Message-ID: <20220506094225.181815-1-michal.orzel@arm.com> (raw)
This patch series modifies macros inside xen/arch/arm/include/asm/grant_table.h
to be resistant to static analyzer/compiler warnings about unused-but-set
variables.
The first patch acts as a fix for a gcc warning when -Wunused-but-set-variable
flag is enabled by converting the macro to static inline helper. The
adjacent macro is modified as well. These macros can be converted to inline
helpers as they do not take argument of type struct grant_table which is not
fully defined yet.
The second patch modifies the remaining macros to evaluate all their arguments
and only once.
