From c344675ad267040b1794b0b5d85147a5023c548d Mon Sep 17 00:00:00 2001 From: Ruidong Tian Date: Thu, 14 Dec 2023 20:33:03 +0800 Subject: perf scripts python arm-cs-trace-disasm.py: Set start vm addr of exectable file to 0 For exectable ELF file, which e_type is ET_EXEC, dso start address is a absolute address other than offset. Just set vm_start to zero when dso start is 0x400000, which means it is a exectable file.
