# On HP-UX we do not want _fixtfdi, _fixunstfdi, or _floatditf from

# to 80 bit conversions and were done for Linux backwards compatibility.

# We get an undefined main when building a cross compiler because our
# linkspec has "-u main" and we want that for linking but it makes
# LIBGCC1_TEST fail because it uses -nostdlib -nostartup.


# We do not want to include the EH stuff that linux uses, we want to use
# the HP-UX libunwind library.



# Must include -lunwind in the link, so that has the necessary
# DT_NEEDED entry for libunwind.
