From 6eac171f0624303d944ff1a1ae4d0e3b0a63c800 Mon Sep 17 00:00:00 2001 From: Tom de Vries Date: Fri, 16 Aug 2019 00:25:14 +0200 Subject: [PATCH] [gdb] Make maint info sections print relocated addresses When running gdb.base/compare-sections.exp with -fPIE/-pie, we get: ... print /u *(unsigned char *) 0x00000238^M Cannot access memory at address 0x238^M (gdb) FAIL: gdb.base/compare-sections.exp: read-only: get value of read-only section ... The problem is that that "maint info sections" prints an unrelocated address: ... [0] 0x00000238->0x00000254 at 0x00000238: .interp ALLOC LOAD READONLY \ DATA HAS_CONTENTS ... while the test expects a relocated address. Given that the documentation states that the command displays "the section information displayed by info files", and that info files shows relocated addresses: ... 0x0000555555554238 - 0x0000555555554254 is .interp ... fix this by showing relocated addresses for maint info sections as well.
