Subject: [PATCH v1 0/6] config file/command line for objdump & addr2line

Allow objdump to be set as a perf config file variable. As previously
objdump was set via the command line, the string was owned by
argv. Now the string must be strdup-ed, so the corresponding logic
needs changing with an annotation_options__init/exit.

Add command line and config file options for addr2line, set in
symbol_conf for convenience. This doesn't allow the setting of
llvm-addr2line due to a bug, but could in the future.

Ian Rogers (6):
  perf annotate: Delete session for debug builds
  perf report: Additional config warnings
  perf annotate: Add init/exit to annotation_options remove default
  perf annotate: Own objdump_path and disassembler_style strings
  perf annotate: Allow objdump to be set in perfconfig
  perf symbol: Add command line support for addr2line path
