Notes for libalog - reproducible builds result

Version annotated: 0.6.1-6
Identified issues:
Identifier: ada_gprbuild_gcc_records_temp_paths
Description In the -dbgsym package for an Ada library, the output of
readelf --debug-dump=info /usr/lib/usr/lib/debug/.build-id/*/*.debug
matches
DW_AT_producer GNU Ada -g -gnate[cm]=/tmp/GNAT-TEMP-[digits].TMP
.
The files are created by gprbuild for GCC subprocesses.
The enumeration order varies during parallel builds.
This issue differs from gcc_captures_build_path and cannot be
solved by *-file-prefix-map.
.
Fix: pass -cargs:ada -gno-record-gcc-switches -gargs to gprbuild.
Packages using debian_packaging.mk from gnat>=11.2 require no
intervention.
Identifier: unknown_ada_issue
Description Previously part of build_id_variation_requiring_further_investigation
.
Symptoms are similar to random_order_in_static_libraries.
Not to be confused with timestamps_in_ada_library_information_files,
buildpath_in_binaries_generated_by_ada_compiler,
cflags_recorded_in_ada_ali_files.
