# The binutils c++filt program wants to know whether underscores are
# stripped or not.  It uses this information to choose a default.
# This information is duplicated in the symbol_leading_char field of
# the BFD target vector, but c++filt does not deal with object files
# and is not linked against libbfd.a.  It is not terribly important
# that c++filt get this right; it is just convenient.

#  Make sure that the left side always has two dashes.  Otherwise you
#  can get spurious matches.  Even for unambiguous cases, do this as a
#  convention, else the table becomes a real mess to understand and maintain.
