+== separate debuginfo conventions ==
+
+We have the existing convention of a debuginfo path, with directories like
/usr/lib/debug wherein we look up individual ELF files' .debug counterpart
file. The old convention is by name (/usr/lib/debug/usr/bin/foo.debug for
/usr/bin/foo with .gnu_debuglink foo.debug). The new convention (tried first)
is by build ID (/usr/lib/debug/.build-id/xx/xxx... in lowercase hex of the
build ID bits), yielding a symlink to the individual .debug file (->
../../usr/bin/foo.debug).
+
+If we go whole hog on DwarfInterObject debug.a format, then we no longer have
individual .debug ELF files to find.
+
+ * Compatibility:
+ For older tools (gdb, crash, etc), have an exploder tool that turns debug.a
back into individual .debug files (with copies in place of interobject refs).
+ * New lookup convention.
+ 1. Could keep .build-id/xx/... symlink convention, but when the symlink is
to an archive, find the ELF member with matching ID.
+ a. Symlink has automagic tie in for RpmDebugInfo to enable {{{yum
install /usr/lib/debug/.build-id/...}}}
+ 1. Just check all of /usr/lib/debug/*/debug.a by that name convention,
match IDs inside (same even by name w/o IDs?)
+ 1. Some new kind of lookup database in /usr/lib/debug/.build-id/something
+ a. Separate ones would be same as */debug.a with internal ID map.
+ b. Consolidated database in /usr/lib/debug needs fiddler tool,
RpmDebugInfo %post magic (or resp. other packaging systems)
+
+ build ID lookup map
+
+Build IDs lend themselves to a sorted table optimized for binary search. A
quick lookup table could be inside each package's debug.a like a
{{{__.SYMDEF}}} pointing to the archive member with the ID. A consolidated
table in a file could point to the archive files by name; putting it like that
makes the symlink hack sound OK.
+
+Lookup table would indicate: number B of bytes in a build ID, number N of IDs
in the table. Then an array of N offsets (archive member offsets or offsets
into a string table), followed by N*B bytes giving the corresponding array of N
B-byte IDs. The arrays are sorted by memcmp ordering of the IDs. Binary
search by ID value is optimal, and the offset fields are aligned regardless of
B.

dwfl_module_addrinfo and @plt entries
Hello, how do I get symbol information for @plt entries? Consider the following case: ~~~ $ objdump -j .plt -S lab_mandelbrot | head lab_mandelbrot: file format elf64-x86-64 Disassembly of section .plt: 2aa0 <_ZN7QWidget4showEv@plt-0x10>: 2aa0: ff 35 62 35 20 00 pushq 0x203562(%rip)# 206008 <_GLOBAL_OFFSET_TABLE_+0x8> 2aa6: ff 25 64 35 20 00 jmpq *0x203564(%rip)# 206010 <_GLOBAL_OFFSET_TABLE_+0x10> 2aac: 0f 1f 40 00 nopl 0x0(%rax) ~~~ Now I report dwfl the above binary at address 0x56360eaff000. Then I try to get information about the address 0x56360EB01AA0 (i.e. at offset 0x2aa0, corresponding to the @plt entry above). dwfl_module_addrinfo returns a NULL string, and offset equals the input address. So, how do I use the dwfl API to also get sym names for @plt entries like in the case above?
