Implementing Library calls

[John Lu <jlu at lsil dot com>]

Hi,

I'm working on a port where a long->float conversion is done
by a library call.  The calling convention requires that the long
be passed in memory.  I have a problem when making a call like:

	long foo;
	printf("%E",((float) foo));
	
All the arguments to printf are passed in memory.  The pointer to the
string is placed in memory, but then it is clobbered by the call to
the long->float conversion, since the long argument is passed in memory.
When I invoke, emit_library_call_value(), for the long->float conversion, 
I've used LCT_CONST and LCT_NORMAL for the libcall_type argument, but 
neither fixes my problem.

Thanks,
John Lu
