Subject: [Cocci] [PATCH v4 12/14] parsing_c: parser: cpp_other end attributes production
Date: Fri,  5 Jun 2020 19:13:20 +0530	[thread overview]
Message-ID: <20200605134322.15307-13-jaskaransingh7654321@gmail.com> (raw)
In-Reply-To: <20200605134322.15307-1-jaskaransingh7654321@gmail.com>

Add a production for a macro call in the cpp_other rule of Coccinelle's
C parser. This parses the following C code from Linux v5.6-rc7
successfully:

  arch/x86/kernel/irq_64.c:

	DEFINE_PER_CPU_PAGE_ALIGNED(struct irq_stack, irq_stack_backing_store) __visible;
