# 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.

# ??? Hack to get -P option used when compiling lib1funcs.asm, because Intel
# assembler does not accept # line number as a comment.

# C++ part of libgcc2, hence it had to be disabled.  Must find some other way
# to support the Intel assembler.
