Subject: [PATCH 12/12] efi: make const array 'apple' static
Date: Thu,  8 Mar 2018 08:00:20 +0000	[thread overview]
Message-ID: <20180308080020.22828-13-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20180308080020.22828-1-ard.biesheuvel@linaro.org>

From: Colin Ian King <colin.king@canonical.com>

Don't populate the const read-only array 'buf' on the stack but instead
make it static. Makes the object code smaller by 64 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
   9264	      1	     16	   9281	   2441	arch/x86/boot/compressed/eboot.o

After:
   text	   data	    bss	    dec	    hex	filename
   9200	      1	     16	   9217	   2401	arch/x86/boot/compressed/eboot.o

(gcc version 7.2.0 x86_64)
