#
# These are a few options for reducing the binary size and disk space
# usage.
# - IMPALA_MINIMAL_DEBUG_INFO=true changes the build to produce only
#   minimal debuginfo (i.e. -g1). This has line tables and can do backtraces,
#   but it doesn't include variable information and limits further
#   debuggability. This option reduces the size of binaries by 60+%.
# - IMPALA_COMPRESSED_DEBUG_INFO=true changes the build to compress the
#   debug info with gzip. This significantly reduces the size of the
#   binary without changing the quantity of debug information. The catch
#   is that tools need to support it. gdb is known to support it and
#   the Breakpad scripts have been modified to handle it, but there may
#   be other tools that do not know how to use it. This reduces the size
#   of binaries by 50+%.
# - IMPALA_SPLIT_DEBUG_INFO=true changes the build to put debug info in
#   separate .dwo files for each C++ file. Executables contain metadata
#   pointing to these .dwo files without needing to incorporate the debug
#   information. This allows executables to share a single copy of
#   the debug information. It also reduces link time, as the linker does
#   not need to process the debug info. Tools (including gdb) mostly know
#   how to handle this split debug information.
#
# Due to the major reduction in binary size and broad support in debugging
# tools, compressed debug information is enabled by default.
