[PATCH 04/17] perf annotate: Rename symbol__annotate() to symbol__disassemble()

Show all headers | View raw

From: Arnaldo Carvalho de Melo <acme@redhat.com>

This function will not annotate anything, it will just disassembly the
given map->dso and symbol.

It currently does this by parsing the output of 'objdump --disassemble',
but this could conceivably be done using a library or an offshot of
the kernel's instruction decoder (arch/x86/lib/inat.c), etc.
