* addr2line.c: support debuglink by build_idYusuke Endoh2020-12-111-3/+59
| | | | | | | | | | | | | Currently, addr2line.c supports only one path format of debuglink: "/usr/lib/debug/usr/bin/ruby.debug". However, recent debian packages seem to use another format by build_id: "/usr/lib/debug/.build-id/ab/cdef1234.debug". https://github.com/Debian/debhelper/blob/5d1bb29841043d8e47ebbdd043e6cd086cad508e/dh_strip#L292 https://github.com/Debian/debhelper/blob/5d1bb29841043d8e47ebbdd043e6cd086cad508e/dh_strip#L353 This changeset makes ruby backtrace support the second format.
* Show C backtrace appropriately at core dump for GCC 8 or laterYusuke Endoh2020-12-111-0/+1

Until GCC 7, all function locations are represented by a pair of DW_AT_low_pc and DW_AT_high_pc in DWARF information. But since GCC 8, some functions are split to multiple chunks, which are represented by DW_AT_ranges. DW_AT_ranges are represented as offsets from a base address. According to DWARF specification, it is the base address of the compilation unit, but GCC seems to use zero as default. The function "di_read_cu" in addr2line.c had a comment about the fact. However, the base address wasn't initialized as zero.
