From e3168ef921b2b0c62e82c87d2c034706f9d0bc35 Mon Sep 17 00:00:00 2001 From: Fangrui Song Date: Wed, 25 Mar 2020 09:42:57 -0700 Subject: [PATCH] powerpc/boot: Delete unneeded .globl _zimage_start commit 968339fad422a58312f67718691b717dac45c399 upstream. .globl sets the symbol binding to STB_GLOBAL while .weak sets the binding to STB_WEAK. GNU as let .weak override .globl since binutils-gdb 5ca547dc2399a0a5d9f20626d4bf5547c3ccfddd (1996). Clang integrated assembler let the last win but it may error in the future. Since it is a convention that only one binding directive is used, just delete .globl.
