libdw: Search for abstract origin in the correct CU

2023-01-22T00:33:39+00:00

With gcc -flto the abstract origin of an inlined subroutine
could be in a different CU. dwarf_getscopes might return an
empty scope if it cannot find the abstract origin scope. So
make sure to search in the

We also tried to add the origin match in pc_record directly
in the current inlined scope. This always failed, causing
to do a needless traversal, followed by the full CU scan in
dwarf_getscopes. Just always stop the pc_record search and
then do the CU origin_match in dwarf_getscopes.

Do not use relative include paths in library files.

2022-12-20T17:41:05+00:00

Rely on include dirs being set up correctly. Setup libdw AM_CPPFLAGS
to include libebl directory. In libdwfl note that debuginfod.h is a
generated file in the builddir. Only include it in the one file
debuginfod-client.c that really needs it.

libdw: Don't dereference and assign values we are skipping

2022-11-03T12:44:35+00:00

We don't use the FDE address encoding byte, so no reason
to read and store it. Just skip past it.

DW_LLE_GNU_view_pair is used by gcc -gvariable-location-views=incompat5.
As described in http://www.fsfla.org/~lxoliva/papers/sfn/dwarf6-sfn-lvu.txt

libdwfl: add dwfl_report_offline_memory

2022-10-16T15:09:42+00:00

This method allows to read and report ELF from memory instead of opening
a file. That way arbitrary memory can be worked with, e.g. when coming
from a stream without the need to persist.

Another useful application is for fuzzing, because fuzzers might be able
to track accesses to the memory and change the fuzzer input to cover
more edge cases through more targeted input. Hence, add a new function
along with a test case.
