* perf jit: add source line info supportStephane Eranian2016-02-051-0/+610
This patch adds source line information support to perf for jitted code. The source line info must be emitted by the runtime, such as JVMTI. Perf injects extract the source line info from the jitdump file and adds the corresponding .debug_lines section in the ELF image generated for each jitted function. The source line enables matching any address in the profile with a source file and line number. The improvement is visible in perf annotate with the source code displayed alongside the assembly code. The dwarf code leverages the support from OProfile which is also released under GPLv2. Copyright 2007 OProfile authors.
