From 3c6622e22b0e1b2a8ceea6465ea84c6fb8299518 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Mon, 25 Mar 2013 23:21:16 -0700 Subject: binutils: Don't generate .PPC.EMB.apuinfo sections for 64-bit output This can cause issues building ppc64/eabi kernel.

These originate, I think, from the old e500 ABI; in +any case, they are only defined for 32-bit ABIs, and there is a +significant amount of code in bfd/elf32-ppc.c to handle them +appropriately, none of which is in elf64-ppc.c. However, the +assembler can generate them when building 64-bit code for processors +such as e5500 (which uses PPC_OPCODE_E500MC). In such circumstances, +they get generated as PROGBITS rather than NOTE sections, which +reportedly can cause problems in a Linux kernel build. + +Since these sections are only defined in 32-bit ABIs, I think it's +most appropriate to avoid generating them for 64-bit output, which +this patch does. + +Upstream-Status: Backport + +-Khem 2013/03/25 + +From d77411f56a85225e3f7b674e7172c712f6cd61cb Mon Sep 17 00:00:00 2001 +From: Joseph Myers +Date: Fri, 25 Jan 2013 02:02:20 +0000 +Subject: [PATCH] * config/tc-ppc.c (md_assemble): Do not generate + APUinfo sections for 64-bit output. + +--- + gas/ChangeLog | 5 +++++ + gas/config/tc-ppc.c | 3 ++- + 2 files changed, 7 insertions(+), 1 deletion(-) + +diff --git a/gas/config/tc-ppc.c b/gas/config/tc-ppc.c +index fd15bea..0929e52 100644 +--- a/gas/config/tc-ppc.c ++++ b/gas/config/tc-ppc.c +@@ -3249,7 +3249,8 @@ md_assemble (char *str) + + #ifdef OBJ_ELF + /* Do we need/want an APUinfo section? */ +- if ((ppc_cpu & (PPC_OPCODE_E500 | PPC_OPCODE_E500MC | PPC_OPCODE_VLE)) != 0) ++ if ((ppc_cpu & (PPC_OPCODE_E500 | PPC_OPCODE_E500MC | PPC_OPCODE_VLE)) != 0 ++ && !ppc_obj64) + { + /* These are all version "1". */ + if (opcode->flags & PPC_OPCODE_SPE) +-- +1.7.9.5 + -- cgit v1.2.3
