From f5812a7a336fb952d819e4427b9a2dce02368e82 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 30 Jun 2009 11:43:17 -0300 Subject: perf_counter tools: Adjust only prelinked symbol's addresses I.e. we can't handle these two kinds of files in the same way: 1) prelinked system library: [acme@doppio pahole]$ readelf -s /usr/lib64/libdw-0.141.so | egrep 'FUNC.+GLOBAL.+dwfl_report_elf' 278: 00000030450105a0 261 FUNC GLOBAL DEFAULT 12 dwfl_report_elf@@ELFUTILS_0.122 2) not prelinked library with debug information from a -debuginfo package: [acme@doppio pahole]$ readelf -s /usr/lib/debug/usr/lib64/libdw-0.141.so.debug | egrep 'FUNC.+GLOBAL.+dwfl_report_elf' 629: 00000000000105a0 261 FUNC GLOBAL DEFAULT 12 dwfl_report_elf [acme@doppio pahole]$ Now the numbers I got for a pahole perf run are in line with the numbers I get from oprofile.
