2020-11-27perf probe: Change function definition check due to broken DWARFMasami Hiramatsu2-4/+19
Since some gcc generates a broken DWARF which lacks DW_AT_declaration attribute from the subprogram DIE of function prototype. (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97060) So, in addition to the DW_AT_declaration check, we also check the subprogram DIE has DW_AT_inline or actual entry pc.

2020-11-27perf probe: Fix to die_entrypc() returns error correctlyMasami Hiramatsu1-0/+8
Fix die_entrypc() to return error correctly if the DIE has no DW_AT_ranges attribute. Since dwarf_ranges() will treat the case as an empty ranges and return 0, we have to check it by ourselves.
