+# conflict with libgcc2.c files.  We used to use __ia64 as a prefix, now
+# we use __ as the prefix.  Note that L_divdi3 in libgcc2.c actually defines
+# a TImode divide function, so there is no actual overlap here between
+# libgcc2.c and lib1funcs.asm.

+# ??? This breaks C++ pragma interface/implementation, which is used in the
