From faedc380129501bdd7f669bf14e9c7ee3e7a2feb Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Fri, 24 Jul 2020 15:49:01 -0700 Subject: powerpc/64s: allow for clang's objdump differences Clang's objdump emits slightly different output from GNU's objdump, causing a list of warnings to be emitted during relocatable builds. E.g., clang's objdump emits this: c000000000000004: 2c 00 00 48 b 0xc000000000000030 ... c000000000005c6c: 10 00 82 40 bf 2, 0xc000000000005c7c while GNU objdump emits: c000000000000004: 2c 00 00 48 b c000000000000030 <__start+0x30> ... c000000000005c6c: 10 00 82 40 bne c000000000005c7c Adjust llvm-objdump's output to remove the extraneous '0x' and convert 'bf' and 'bt' to 'bne' and 'beq' resp. to more closely match GNU objdump's output. Note that clang's objdump doesn't yet output the relocation symbols on PPC.
