Subject: [PATCH] perf annotate: Allow whitespace between insn operands
Date: Mon, 12 Jun 2023 16:00:26 -0700 [thread overview]
Message-ID: <20230612230026.3887586-1-namhyung@kernel.org> (raw)
The llvm-objdump adds a space between the operands while GNU objdump
does not. Allow a space to handle the both.
In GNU objdump:
Disassembly of section .text: here
|
ffffffff81000000 <_stext>: v
ffffffff81000000: 48 8d 25 51 1f 40 01 lea 0x1401f51(%rip),%rsp

ffffffff8100000c: 48 8d 3d ed ff ff ff lea -0x13(%rip),%rdi
In llvm-objdump:
