Subject: [PATCH v7 12/28] x86/boot/compressed: annotate data appropriatelly
Date: Wed, 30 Jan 2019 13:46:55 +0100 [thread overview]
Message-ID: <20190130124711.12463-13-jslaby@suse.cz> (raw)
In-Reply-To: <20190130124711.12463-1-jslaby@suse.cz>
Use the new SYM_DATA, SYM_DATA_START, and SYM_DATA_END* macros for data.
Now, the data in the object file look sane:
Value Size Type Bind Vis Ndx Name
0000 10 OBJECT GLOBAL DEFAULT 3 efi32_boot_gdt
000a 10 OBJECT LOCAL DEFAULT 3 save_gdt
0014 8 OBJECT LOCAL DEFAULT 3 func_rt_ptr
001c 48 OBJECT GLOBAL DEFAULT 3 efi_gdt64
004c 0 OBJECT LOCAL DEFAULT 3 efi_gdt64_end
0000 48 OBJECT LOCAL DEFAULT 3 gdt
0030 0 OBJECT LOCAL DEFAULT 3 gdt_end
0030 8 OBJECT LOCAL DEFAULT 3 efi_config
0038 49 OBJECT GLOBAL DEFAULT 3 efi32_config
0069 49 OBJECT GLOBAL DEFAULT 3 efi64_config
All have correct size and type now.
