Edit: /usr/lib/rpm/find-debuginfo.sh (20054B)

#!/bin/bash
#find-debuginfo.sh - automagically generate debug info and file list
#for inclusion in an rpm spec file.
#
# Usage: find-debuginfo.sh [--strict-build-id] [-g] [-r] [-m] [-i] [-n]
#			   [--keep-section SECTION] [--remove-section SECTION]
#			   [--g-libs]
#	 		   [-j N] [--jobs N]
#	 		   [-o debugfiles.list]
#	 		   [-S debugsourcefiles.list]
#			   [--run-dwz] [--dwz-low-mem-die-limit N]
#			   [--dwz-max-die-limit N]
#			   [--build-id-seed SEED]
#			   [--unique-debug-suffix SUFFIX]
#			   [--unique-debug-src-base BASE]
#			   [[-l filelist]... [-p 'pattern'] -o debuginfo.list]
#			   [builddir]
#
# The -g flag says to use strip -g instead of full strip on DSOs or EXEs.
# The --g-libs flag says to use strip -g instead of full strip ONLY on DSOs.
# Options -g and --g-libs are mutually exclusive.
# The -r flag says to use eu-strip --reloc-debug-sections.
# Use --keep-section SECTION or --remove-section SECTION to explicitly
# keep a (non-allocated) section in the main executable or explicitly
# remove it into the .debug file. SECTION is an extended wildcard pattern.
# Both options can be given more than once.
#
# The --strict-build-id flag says to exit with failure status if
# any ELF binary processed fails to contain a build-id note.
# The -m flag says to include a .gnu_debugdata section in the main binary.
# The -i flag says to include a .gdb_index section in the .debug file.
# The -n flag says to not recompute the build-id.
#
# The -j, --jobs N option will spawn N processes to do the debuginfo
# extraction in parallel.
#
# A single -o switch before any -l or -p switches simply renames
# the primary output file from debugfiles.list to something else.
# A -o switch that follows a -p switch or some -l switches produces
# an additional output file with the debuginfo for the files in
# the -l filelist file, or whose names match the -p pattern.
# The -p argument is an grep -E -style regexp matching the a file name,
# and must not use anchors (^ or $).
#
# The --run-dwz flag instructs find-debuginfo.sh to run the dwz utility
# if available, and --dwz-low-mem-die-limit and --dwz-max-die-limit
# provide detailed limits.  See dwz(1) -l and -L option for details.
#
# If --build-id-seed SEED is given then debugedit is called to
# update the build-ids it finds adding the SEED as seed to recalculate
# the build-id hash.  This makes sure the build-ids in the ELF files
# are unique between versions and releases of the same package.
# (Use --build-id-seed "%{VERSION}-%{RELEASE}".)
#
# If --unique-debug-suffix SUFFIX is given then the debug files created
# for <FILE> will be named <FILE>-<SUFFIX>.debug.  This makes sure .debug
# are unique between package version, release and architecture.
# (Use --unique-debug-suffix "-%{VERSION}-%{RELEASE}.%{_arch}".)
#
# If --unique-debug-src-base BASE is given then the source directory
# will be called /usr/debug/src/<BASE>.  This makes sure the debug source
# directories are unique between package version, release and architecture.
# (Use --unique-debug-src-base "%{name}-%{VERSION}-%{RELEASE}.%{_arch}".)
#
# All file names in switches are relative to builddir (. if not given).
#

# Figure out where we are installed so we can call other helper scripts.
